System Features

This feature provides the station user with the capability of entering anaccount code for both incoming and outgoing calls. The entry may beforced (which applies only to outgoing calls) or optional. Forced accountcodes can be applied to either all calls or to toll calls only. This option isset in the system database.

Forced Account Code requirement is designated by the station’sprogrammed parameters. If an account code is required, the user will beprompted for account code entry after the last destination digit has beendialed. The call will be processed after the account code has beenentered.

If account code entry is optional, the user may enter the code during a callby using either an Account Code access key or the Account Code accesscode. When using an access key, the user presses the Account Codeaccess key and enters the required account code. When using theAccount Code access code, the user presses the hookswitch orConference/Transfer key to hold the current call, enters the Account Codeaccess code, and then enters the required account code.

A station that requires Forced Account Code entry can access unrestrictedtrunk groups without the entry of an account code.

If either an on-hook or off-hook camp-on is initiated by a station user whohas entered an account code, the system will retain the code until thecamp-on is canceled or until the call is completed. The station user doesnot have to re-enter the account code when the connection is established.

A station user may enter any number of account codes during a call;however, only the last valid entry will be recorded on the Station MessageDetail Recording (SMDR) record. All account codes in a system must beof the same length.

Calls prefixed by "911" or "800" are always considered toll-free and do notrequire account code entry.

System FeaturesACCOUNT CODE/VERIFIABLE PERCEPTION 4000

The Account Code/Verifiable feature allows account codes to be verifiedwithin the system. Both forced and optional account codes may beselected for verification. With forced account codes, calls will be allowedonly if the entered account code is valid. Verifiable account codes applyonly to outgoing calls.

The system may be programmed to automatically verify account codesthat are entered on a forced basis after dialing a destination, or on anoptional basis during a call. Actual account code entry is performed via theuse of a designated Account Code feature access key or code.

Forced Entry After the Destination Number:Stations may be configured as forced account code stations by an M&Acommand. If account code entry is mandatory, the user will receive recalldial tone following entry of the last digit of the destination number, andmust enter an account code to continue the call. When the account code isentered, the system will check the code against the codes listed in thedatabase. If a match is found, the user will receive success tone, and thecall will be placed. If an invalid account code is entered, the user willreceive reorder tone, and the call will not be placed.

Optional Entry During a Call:A station user may override the initial account code entry by enteringanother account code during a call. If the system Account Code Verifiablefeature is set, the new account code will then be verified against thoselisted in the database. If a match is found, then the account code will beregistered within the system.

When using a feature access key for optional account code entry, the entryprocedure is completely transparent to the distant party. The station usersimply presses the Account Code feature access key and enters theappropriate destination number. If the entered account code is acceptedby the system, then the Account Code key's LED will go out after theaccount code is entered. If the entered code is not accepted, then theAccount Code key's LED will flash red. In either case, there will be nointerruption to the existing conversation.

When using a feature access code for optional account code entry, theuser must ask the existing caller to wait while the account code is beingentered. The user then presses the Conference/Transfer key, enters theAccount Code feature access code, listens for recall dial tone, enters theappropriate account code, and then waits for success tone. Once successtone times out, the user will be reconnected to the held call. If an invalidaccount code is entered, the user will receive reorder tone for a briefperiod and will then be reconnected to the call.

An invalid account code will not be recorded by SMDR. Account codesmay be overridden as many times as required. However, only the lastverifiable account code entered will be printed on the SMDR printout;invalid account codes are not included in the SMDR bit stream.

System Features

Trunk-ended announcement machines are used in conjunction withAutomatic Call Distribution (ACD), Uniform Call Distribution (UCD), VacantNumber Intercept, and other intercept treatments to provide recordedannouncements. Any util ized announcement machine must be aStart/Stop Arrangement type machine.

Each Start/Stop Arrangement type announcement machine has one ormore channels, which are each used to record and transmit a differentmessage. Each channel can be assigned to a trunk port via Maintenanceand Administration (M&A) commands. A number of calling parties can besimultaneously connected to the same dedicated announcement port toreceive a pre-recorded message.

If programmed in the database, an incoming call will be automaticallyconnected to a customer-provided recorded announcement machine, andthe caller will hear the appropriate recorded announcement.

Different voice announcements can be specified for different interceptconditions. Once indicated in the system database, an intercepted call willbe automatically routed to the appropriate announcement. The followingcalls are usually routed to an announcement machine to receive aprerecorded message:� Incoming DID calls that attempt to reach a vacant number or a

permanently-restricted station.� Incoming calls that have waited in an ACD/UCD queue for over a

specified period.� Incoming calls that have been intercepted and cannot be completed.

APPLICATION PROCESSORS PERCEPTION 4000

The PERCEPTION® 4000 system can connect to external processors toprovide additional features and system data analysis. These externalprocessors are known as Application Processors. Currently, thePERCEPTION 4000 system supports three types of ApplicationProcessors—the PERCEPTION 4000 Automatic Call Distribution/Management Information System (ACD/MIS), Station Message DetailAnalysis (SMDA), and Voice Mail. Each application processor is connectedto the PERCEPTION 4000 system via an RS-232-C port and is supportedby the MISC card.

Automatic Call Distribution (ACD), a feature of the PERCEPTION 4000system, is the most cost-effective method for distributing large volumes ofincoming calls to call centers. The calls are served in the order of arrivaland are evenly distributed among the ACD agents.

The PERCEPTION 4000 Automatic Call Distribution/ManagementInformation System (ACD/MIS) is an external application processor whichreports information regarding ACD feature operation. ACD/MIS receivesACD agent and group data from the PERCEPTION 4000 system andorganizes the data into real-time status displays and historical reports.These then enable the end-user to maximize the efficiency andproductivity of the ACD operation.

Further information about the ACD/MIS application processor can befound in the ACD and ACD/MIS General Description, ACD Agent UserGuide, ACD and ACD/MIS Supervisor’s Guide, ACD/MIS Administrator’sGuide, and ACD/MIS Installation and Maintenance Manual.

Station Message Detail Analysis (SMDA) is a customer-provided externalapplication processor which is a comprehensive call accounting package.SMDA is designed to collect call records in real-t ime from thePERCEPTION 4000 system, compute their cost, and store them for futurereference. Upon user command, the SMDA system analyzes the storedcall records and generates reports. The types of reports may varydepending on the equipment selected; however, four types of reports areusually available: Cost Allocation, Cost Control, Trunk Traffic, andAdministration.

Cost Allocation reports typically include Chronological Call Reports,Immediate Printout Reports, Call Detail by Extension, Call Detail byExtension for an Extension Group, Call Summary by Extension for anExtension Group, Call Detail for an Account Number, Call Summary byAccount Number, etc.

Cost Control reports generally contain reports for Most Expensive Calls,Longest Calls, Call Detail for a Selected Call Number, etc.

Trunk Traffic reports typically include Call Summary Reports by TrunkGroup, by Area Code, by Office Code, by Cost Type, etc.

Typical Administration reports that are available include Telephone

For detailed information regarding SMDA options and operations, refer todocumentation supplied by the manufacturer of the utilized SMDAequipment.

The use of a voice mail system provides an electronic method of sendingand receiving messages that is void of the problems associated withtraditional messaging techniques (misplaced notices, unreceivedmessages, etc.). A voice mail system provides voice messagingcapabilities that can be accessed from any Dual-tone Multi-frequency(DTMF), push-button telephone. When used properly, voice mail is apowerful tool to improve communications, control communications costs,and increase internal information flow.

A feature-rich voice messaging system provided by Toshiba is available ina variety of sizes to meet customers' varying requirements. This systemcan be integrated with the PERCEPTION 4000 system to provide userswith voice mail sending options, integrated message notification,automatic attendant services, and flexible call routing. Integration with thePERCEPTION 4000 system is performed through a standard RS-232-Clink.

For customers who prefer to utilize their present voice mail system, thePERCEPTION 4000 system supports the Bell Communications ResearchSimplified Message Desk Interface (SMDI), Technical Reference TR-TSY-000283, Issue 1, July 1985. Voice mail systems which support thisinterface can be integrated with the PERCEPTION 4000 system, to obtainenhanced message notification and retrieval features. Since SMDI is notenforced as an industry standard, each vendor's implementation of theinterface may vary. Toshiba has tested the SMDI implementation of manyvoice mail systems. For information on the results of these tests, or todetermine the compatibility of a particular voice mail system, consult yourToshiba sales representative. SMDI is an optional feature of thePERCEPTION 4000 system.

The integration of a voice mail system with the PERCEPTION 4000system provides station users with designated voice "mailboxes," in whichmessages can be left and then retrieved. Station users can forward theirstation's calls to the directory number of the voice mail system, on eitheran all calls, no answer, or busy/no answer basis. When a call is forwardedto a mailbox, the caller will hear the user's personal greeting and will thenbe able to leave a message. Users can also leave or retrieve voice mailmessages by directly calling the directory number of the voice mailsystem.

When a message is left in a station user's mailbox, that station's MessageWaiting key LED or Message Waiting light will light to indicate the waitingmessage. Display telephones will also indicate the waiting messagethrough a message on the Liquid Crystal Display.

The retrieval of voice mail messages can be initiated by simply pressing a

System FeaturesPERCEPTION 4000 AUTOMATIC CALL DISTRIBUTION

Automatic Call Distribution (ACD) allows a large number of calls to arelated group of stations (agents) to be distributed for more efficient callhandling. Stations that are members of ACD groups can be any Toshibadigital or electronic telephone, or any 500/2500 standard telephone.Because of the helpful display information available through ACDoperation, display telephones are recommended for agent stations.

Each ACD group has an assigned pilot number, to which all ACD calls aredirected. A call to the ACD group pilot number will be distributed to anavailable agent in the group. A call can also be routed to an ACD groupthrough programmed inward routing.

Each ACD group is identified by its ACD group pilot number. The ACDagents within a group are identified by their ID codes (which do not conflictwith the system’s numbering plan). An ACD agent can move from oneagent position to another by logging into the system with his/her ID code.The system accumulates the statistics against the ID code instead ofagainst the physical position of a certain telephone.

A supervisor can be assigned for each ACD group. The supervisorystation can be any Toshiba digital or electronic telephone; however,PERCEPTION 4000 20-key digital telephones are highly recommended forthis application because of the telephones' enhanced display capabilities.

An ACD supervisor oversees ACD operation and can provide assistanceto agents. Supervisors also have the option of monitoring customer/agentconversations (a monitor tone may be provided through systemprogramming). With the addit ion of an external Automatic CallDistribution/Management Information System (ACD/MIS) applicationprocessor, a supervisor's CRT terminal can be used to provide helpfulinformation regarding ACD agent status and performance. Reports canalso be generated via a system-connected printer, to provide informationthat can be used to streamline ACD operation for maximum efficiency.Additional details regarding ACD/MIS capabilities can be found in thePERCEPTION 4000 ACD/MIS General Description.

One overflow destination may be assigned for each ACD group. Thisdestination can be either another ACD group or a UCD group. If theoverflow destination is an ACD group, overflow will occur when there is anidle agent in the assigned overflow group. If the overflow destination is aUCD group, overflow will occur regardless of whether there is an idleagent in the assigned overflow group. Calls in an ACD queue will overflowwhen their overflow timers expire. When overflowed to the overflow group,a call will be removed from the call waiting queue. If the assigned overflowgroup is busy, the call will stay in the original queue and will retry again.

AUTOMATIC CALL DISTRIBUTION PERCEPTION 4000

The system may automatically place an ACD agent into an “After CallWork” mode after the agent disconnects from an ACD call. This After CallWork time applies to both incoming and outgoing calls on the ACD line.While in this mode, the agent is unavailable for ACD calls. The agent canexit After Call Work mode either manually or by waiting for the designatedAfter Call Work time period to elapse. Once After Call Work mode isexited, the agent will once again be available for calls.

When all agents have logged out of an ACD group or are unavailable, callscan be routed to a predefined answering position. When the number ofcalls placed to an ACD group reach a threshold limit, all subsequent callswill be redirected to the predefined overflow destinations. Each ACD groupcan be assigned one After Shift answering position. This can be anotherACD group, a Uniform Call Distribution (UCD) group, a Station Huntinggroup, an individual attendant or attendant group, another station, or avoice mailbox. An ACD group will remain in After Shift Service mode untilat least one agent in the group becomes available.

The PERCEPTION 4000 system offers two different algorithms for CallDistribution: Next Available-First and Most Idle-First. Only one algorithmcan be selected and applied on a system level. As calls arrive to an ACDgroup, they will be automatically distributed as instructed by the selectedmethod.

If programmed to do so, calls in queue wil l receive recordedannouncements and/or music. Announcements can be programmed toplay at certain time intervals. Each ACD group can have its own uniqueannouncement and music pattern.

Dialed Number Identification Service (DNIS) is a service provided by theserving Central Office that assigns different 800 numbers to a specificPBX trunk group. This is more efficient than assigning a single 800number to the trunk group and also provides agents with helpful incomingcall identification information. DNIS allows the different 800 numbers (ortheir corresponding service names) to display on an agent's displaytelephone, assisting the agent in answering calls appropriately. In an ACDenvironment, DNIS helps maximize trunk usage and optimize ACD agentcall handling capabilities.

Each ACD group has a queue in which incoming ACD calls wait to beanswered. As agents become available, the calls in queue are served on aFirst-in/First-out (FIFO) basis. If programmed to do so, calls which havenot been answered within a certain time period can overflow to anotherACD or UCD group. While waiting in queue, callers may hear recordedannouncements and/or music.

Priority Queuing allows the system administrator to assign priority levels toincoming ACD calls entering an ACD queue. If all ACD agents are busyand a call must wait in queue, the system will identify the queuing priorityof the call and position it among calls already queued. External callers areassigned priority levels based on the utilized trunk group. Internal callers

are assigned a unique priority determined by their station's assignedqueue priority level. DNIS 800 numbers are assigned unique prioritytreatments which can be programmed to override assigned ACD trunkgroup prioritization. (Refer to the Dialed Number Identification Servicefeature for detailed information on DNIS Priority Queuing.) Priority levelsare numbered from 1 to 16, with 1 being the highest priority level. Callswith the same priority level are unloaded from the queue on a first-in/first-out basis as the agents become available.

Calls in the ACD queue which receive Priority Queuing treatment may beprogrammed to advance to a higher priority position in the queue if the callis not answered within a predetermined period of time. The call will beplaced at the end of the queue priority position to which it advances. Thepriority of a call may be advanced only once during the call's time in anACD queue, and the priority will not be increased if the call has alreadyreached the highest queue priority level.

ACD agents can use headsets to ease ACD call handling. When aheadset is used with a PERCEPTION digital telephone, headset operationcan be controlled via programmed feature access keys. Refer to theHeadset Operation station feature for operational information.

An ACD agent can utilize all features that are ordinarily available to thetelephone being used as an agent station, plus the following additionalfeatures:

A display telephone that is assigned as an ACD agent will display thenumber of calls that are currently waiting in queue to be answered bymembers of the ACD group. This information helps agents determinewhen calls need to be handled more quickly or if additional agents need tologin to handle calls.

Agents can manually exit After Call Work mode by pressing the ACD WorkMode Cancellation (CANC) access key, by waiting for the designated AfterCall Work time period to elapse, or by pressing the ACD line key. In thelatter case, dial tone is given so that the agent may originate another call.Once After Call Work mode is exited, the agent will once again beavailable for calls.

While in an idle or talk state, ACD agents can call their group supervisorfor assistance by pressing the ACD Assistance (ASST) access key. If thisis done in the talk state, then an agent can initiate a three-way conferenceby pressing the Conference/Transfer (CONF/TRNS) key. If the supervisorposition is busy, the agent can initiate either an off-hook or on-hook camp-on. If the supervisor is busy, the agent can use the Camp-on Transferfeature to camp a held call onto the ACD supervisor line.

When an ACD agent position is in the Automatic Answer mode, thesystem will provide an audible burst of tone before automaticallyconnecting an incoming ACD call.

AUTOMATIC CALL DISTRIBUTION PERCEPTION 4000

An ACD agent may originate a call or access a feature from the ACD linewhile logged into an ACD group. The ACD line must be idle with no calls inqueue. Autodial and Speed Calling are supported for call origination viathe ACD line. All dialing privileges and feature access are subject to theClass of Service and Outdialing Restrictions (DRL, FRL, and QPL)assigned to the agent ID code.

Intra-group Call Pickup allows ACD agents to answer ACD calls that ringat other stations within their own ACD group. To answer a ringing call, theagent simply presses the ACD Intra-group Call Pickup (ACDP) access keyand then enters the ID number of the ringing agent telephone. Each agentID number is associated with two flags that are assigned in the systemdatabase. One flag allows/denies a station to pick up calls, while the otherallows/denies a station's calls to be picked up.

An ACD agent can login to an ACD group by pressing the ACD Log (LOG)access key and dialing the group number, followed by the agent'sidentification (ID) code. As soon as an agent logs into the system, he/sheis considered available for incoming ACD calls. An agent can logout at anytime by pressing the LOG access key again.

ACD agents can login to their ACD group from any standard or multi-linetelephone which is not a member of their own ACD group. While beingused as an ACD station, a telephone's prime line becomes a dedicatedACD line. Any other lines on the device remain unaffected and calls canbe originated from those lines. An ACD agent can login to any telephoneby accessing the station's prime line, dialing the remote login access code,and entering his/her ACD group number and agent ID code.

This feature allows an agent to make his/her telephone temporarilyunavailable for ACD calls, without having to logout of the ACD group.When in the Unavailable Mode, the agent is unable to either originate orreceive calls on the ACD line. The agent can activate this feature bypressing the ACD Status (STAT) access key or by entering the ACDUnavailable access code.

In an ACD/MIS environment, ACD agents can enter call identificationcodes, referred to as Work Units, to indicate the nature of ACD calls. WorkUnit codes may be entered during either incoming or outgoing calls. WorkUnits can represent such things as calls to/from a certain company or callsregarding a certain account. Any entered Work Units are statisticallycompiled in the ACD/MIS reports.

An assigned ACD supervisor can access all features that are ordinarilyavailable to a station, plus additional ACD group supervisory andassistance capabilities. These additional capabilities are as follows:

If the supervisor position is idle when an Assistance Call arrives, thesupervisor’s LCD will display “ASSIST PLEASE,” together with the callingagent's name and ID code. If the supervisor's line is busy when theassistance call arrives, the supervisor will hear call waiting tone.

An ACD supervisor will receive an audible alarm indication when the ACDcall queue's upper threshold has been exceeded. The audible alarm willsound until the supervisor presses the ACD Alarm (ALRM) access key.The ALRM key's associated LED will remain flashing until the queue sizereturns to below the lower threshold level.

An ACD supervisor can be allowed to tap into a conversation that exists onan agent's ACD line. Agent Monitoring is available for both incoming andoutgoing calls. Monitored agents can belong to the supervisor's assignedgroup or to other ACD groups. If activated, a three-way conference will beestablished with a one-way, listen-only path for the supervisor. Prior tobeing monitored, an agent can receive an optional low-frequency warningtone. (Certain states may have regulations regarding the monitoring ofcalls without the knowledge of the parties involved. Prior to performing anymethod of call monitoring, these regulations should be identified andfollowed.)

ACD supervisors can answer ACD calls both within their own group andwithin other groups. To answer an ACD call within their own group,supervisors simply press the ACD Intra-group Call Pickup (ACDP) accesskey and enter the agent ID code that applies to the ringing station. Toanswer a call that is ringing at an ACD agent station in another ACDgroup, supervisors press the ACD Inter-group Call Pickup (INTP) accesskey and enter the ACD group number, followed by the agent ID code thatapplies to the ringing station. Supervisors can always pick up a ringingagent call in their group or in another agent group, regardless of theagent's pickup allow/deny status.

An ACD supervisor can login to an ACD group by pressing the ACD Log(LOG) access key and entering a 2-digit ACD group number, followed by apassword and the pound (#) sign. As soon as the supervisor logs in,he/she is available for agent assistance calls and can access ACDsupervisory features. To logout, the supervisor simply presses the LOGkey again.

An ACD supervisor can use his/her supervisory station to log out either anindividual agent or all the agents in his/her ACD group.To log out an agentor agent group, the supervisor presses the Remote Logout (RLOG)access key and then enters the appropriate ACD agent or agent grouplogout code. Autodial (ADL) keys can be programmed with agent IDcodes for use during Supervisor Remote Logout. Individual agents orgroups may be logged out while they are in the busy or idle state. If anagent is in the busy state when remote logout is requested, the agent willbe placed in a "Logout Pending" state and will be logged out when theagent's status is returned to idle.

The display includes thegroup numbers, agent names, agent ID codes, agent type (dedicated,traveling), equipment number (of the agent's station), and the PrimeDirectory numbers of the stations where the agents are logged in. Thisfeature provides a convenient visual means of locating traveling agents.

This feature also provides the supervisor with a means, in addition toSupervisor Remote Logout, of logging out an individual agent or all theagents in an ACD group.

When the PERCEPTION 4000 ACD/MIS application processor is utilized,an ACD group supervisor can request a variety of supervisory reports anddisplays regarding ACD call activity. Supervisors receive displays on adata terminal CRT screen. The CRT unit connects to either an IntegratedData Interface Unit (DIU-I) or a Stand-alone DIU (DIU-S) that is associatedwith the supervisor's station.

When using an ACD/MIS system and a CRT screen, an ACD groupsupervisor can request and receive on-line status displays and reports ofACD group activity. The displays and reports consist of the followinginformation:� Agents logged in and their availability� Agents' cumulative work load and performance since having logged in� Current queue size� The waiting time of the longest-waiting call� ACD groups’ call handling abilities� Warning displays for service level degradation� ACD historical statistics reports

Data regarding ACD can be output from the PERCEPTION 4000 systemto a connected ACD/MIS application processor. Repor ts can begenerated, noting information such as ACD call activities, ACD agentstatus, and ACD queue activities.

Refer to the PERCEPTION 4000 ACD Agent User Guide, ACD andACD/MIS Supervisor’s Guide, and ACD/MIS Administrator’s Guide fordetailed information regarding ACD and ACD/MIS operations.

ACD pilot numbers (not agent or supervisory lines) can be designated asCall Forward termination points. An ACD line key is reserved exclusivelyfor ACD call activity, although an ACD line can be used for call originationif the line is idle and there are no ACD calls currently in queue. An ACDline can also be used to call a third party (for consultation purposes) afterplacing an ACD call on Consultation Hold ("soft hold").

System FeaturesCLASS OF SERVICE PERCEPTION 4000

Class of Service (COS) defines which features and call facilities can beaccessed by each PERCEPTION 4000 station, attendant console, anddata interface unit. Each device has its own assigned COS level, whichallows or denies access to system, station, and data features, as well asoutgoing trunks. Each incoming TIE or DISA trunk group is also assigneda Class of Service.

The PERCEPTION 4000 system supports 64 Classes of Service. EachCOS definition can be applied during various times of the day or week,allowing different calling needs to be accommodated. Each station,attendant console, data device, or trunk can be assigned to up to fourdifferent COS levels for various times of the day or week. Holidays canalso be indicated in the system database, so that any necessary callingallowance/denial changes can be applied on these days.

Class of Service is automatically checked whenever a call is initiated or anaccess code is dialed. If allowed by its COS definition, a device will bepermitted to access the requested feature. If the feature is denied, theattempted call will receive intercept treatment (reorder tone, voiceannouncement, or attendant) and will not be permitted to access thedesired feature.

An authorization code may be used to temporarily override a device'sassigned COS. When an authorization code is used, the enhanced callingprivileges will apply only for the duration of the current call. Once the call isterminated, the device's original COS will be reinstated.

System Features

The PERCEPTION 4000 supports the use of a Coordinated NumberingPlan in a networking environment. This is one of the various types ofnetworking supported by the system. Refer to the PERCEPTION 4000Networking and Uniform Numbering Plan system feature descriptions foradditional networking information.

With a Coordinated Numbering Plan (CNP), each station in the networkhas its own unique directory number. All directory numbers are of thesame length and are not duplicated in any other networked system. Thisarrangement allows station users to easily place calls to other stationswithin the network, since all station-to-station call routing (either direct ormulti-stage) is transparent to the user.

The transparent dialing aspect of CNP is accomplished by the use ofsteering digits. These digits are assigned to the TIE trunk groups thatconnect the various systems (switches) in the network. The first one or twodigits of each station directory number represent the steering digits of thetrunk group that is required to initially route a call out of the originatingsystem. When a station user dials a station directory number, the systemof which the user is a member, recognizes the steering digits andaccesses the appropriate trunk group. Once the correct trunk group isseized, the digits are sent to the terminating switch.

If the station resides in this switch, the call will then be completed to thecalled station. If not, then this switch will recognize the prefix digits of thestation number or steering digit and then select the appropriate trunkgroup needed to route the call. After the trunk group is seized, the systemwill send the digits on to the next switch. This process will continue untilthe digits are sent to the switch in which the called station resides. Thisswitch will then connect the caller to the appropriate station.

Each unique steering digit sequence (usually one or two digits) can onlybe assigned to one trunk group in each switch. This designates a specifictrunk group to be used for each unique call route. Each trunk group,however, can have multiple steering digit sequences assigned to it,allowing the trunk group to be used to route calls to various locations.

A CNP is arranged through software programming in the various systemscontained in the network. Once a CNP has been properly arranged, astation user can dial a station within any of the networked systems bysimply dialing the desired station directory number (usually four or fivedigits). The calling party's system will then select the appropriate TIE trunkgroup on which to route the call, based on the steering digits of the dialedstation number. The system will then send all dialed digits over thenetwork and additional call routing will be performed by other requirednetwork switches.

Forced Account Code entry is not required for CNP calls.

CNP calls are not checked by Outdialing Restrictions.

System FeaturesDATA SWITCHING PERCEPTION 4000

Data Switching through the PERCEPTION 4000 system utilizes thesystem's telephone lines for data transmission. Data can be transmittedand accessed from data devices, including a personal computer, dataterminal, modem, printer, or host computer. Using the PERCEPTION 4000system for data switching also provides data users with calling featuressuch as Data Speed Calling, Least Cost Routing, and Data Port Hunting.

The necessary digital interface for data transmission through thePERCEPTION 4000 system is provided by using either of twoPERCEPTION 4000 data interface units. The Integrated Data InterfaceUnit (DIU-I) resides inside the base of a PERCEPTION 4000 proprietary10-key (HDT2010S) or 20-key (HDT2020SD) digital telephone, while aStand-alone Data Interface Unit (DIU-S) is a separate unit that can beused with a computer, terminal, printer, or modem.

The use of a DIU-I enables a digital telephone user to performsimultaneous voice and data calls. When a DIU-I is used, the digitaltelephone's keys, LEDs, and LCD displays can be used for data calls. Asan option, a computer or ASCII terminal can be connected to the digitaltelephone, so that data calls can be made through keyboard dialing. Whenusing this option, Toshiba's user-friendly software interface, the UserCommand Interface (UCI), is used to place data calls. Throughout datacall setup, helpful displays appear on the CRT screen of the connectedcomputer or terminal.

UCI is also used when placing calls from a computer or terminal that isconnected to a DIU-S. This is ideal in situations where a telephone is notrequired at the site of the data device. A DIU-S can also be used with astand-alone printer and is used for modem pooling, which allows a numberof stations to share modems for the sending and receipt of data calls.

To place a data call from a PERCEPTION 10-key or 20-key digitaltelephone, the user simply presses the data line key and dials thedestination number. If desired, Data Speed Calling can be used toeliminate lengthy dialing procedures. An incoming data call can beanswered by pressing the ringing data line key.

When accessing a modem pool to place a data call, the station user canrequest a specific modem by entering a modem pool access code,entering the number of the desired modem pool, and then dialing thedestination number. If an individual modem is not specified, then a modemwithin the default modem group that is assigned to the calling data station,will be accessed.

To place data calls via UCI, the proper hardware and softwarearrangements must first be made. A computer or ASCII terminal with aCRT screen is required and is connected, via an RS-232-C cable, either toa digital telephone with a DIU-I or to a DIU-S. In order for datatransmission to occur, the following operating details must be properly

System FeaturesDATABASE ADMINISTRATION (M&A) PERCEPTION 4000

The Maintenance and Administration (M&A) functions of thePERCEPTION 4000 system enable system administrators andcraftpersons to communicate with the system to perform all necessarydatabase updates, diagnostics, and reporting. All M&A functions areperformed through the use of an ASCII terminal connected to an M&A porton the PERCEPTION 4000 system (RS-232-C connection). Each M&Acommand allows access to specific database attributes or system controlparameters.

The PERCEPTION 4000 system performs a number of automaticmaintenance functions to maintain uninterrupted system operation. Theseinclude fault detection and identification, redundant-side switchover, andautomatic shutdown. Many of these procedures can also be initiatedmanually. Display and report information regarding the location of asystem fault can be requested through M&A commands. Local tests canalso be performed to verify proper telephone or data device operation.Switchovers and shutdowns can be performed manually through switcheson the status display area of the Top Unit of the System Stack. Refer to theRedundancy, Remote Maintenance, and System Shutdown Proceduresystem features for further information regarding these aspects of M&A.

PERCEPTION 4000 M&A provides the following operating conveniences:

� Man-Machine Interface—The Man-Machine Interface (MMI) is thePERCEPTION 4000 system's M&A interface which provides userswith a user-friendly method of maintaining the system. To ease M&Aoperation, MMI provides users with a variety of help messages, whichcan be accessed at any stage of M&A programming. MMI also allowsthe use of timesaving data entry procedures, such as rangeprogramming and abbreviated programming operations.

� Security Access—There are four separate M&A security levels, whicheach have their own assigned capabilities. The four M&A levels, indescending order of their access capabilities, are: manufacturer level(Toshiba access only), vendor/distributor level; end-user level; andtenant level. The tenant level can be divided into up to 32 separatenon-hierarchical groups of capabilities. Capabilities within thesegroups can overlap. Every operation in an M&A command belongs toa particular category of information, which is assigned to one or moreof the security levels. An M&A user can access a particular level ofM&A through the use of a security code.

� Local/Remote Access—An M&A terminal is connected to thePERCEPTION 4000 system via the Input/Output (I/O) port on the backof the cabinet. The M&A terminal can be located either locally near thePERCEPTION 4000 system, or remotely. Remote access isparticularly beneficial for customers with multiple PBX sites, sinceM&A tasks can be performed from a single location. Communicationwith the PERCEPTION 4000 system can be provided by DirectDistance Dialing, Leased Line, or some other comparable facility,through a standard modem.

Dialed Number Identification Service (DNIS) is an optional serviceavailable from various long distance carriers, which optimizes trunk usageand provides helpful call identification information to answering parties.DNIS involves 800-numbers and is typically related to the use of AutomaticCall Distribution (ACD) groups, although some applications use DNIS forindividual answering positions.

DNIS allows multiple 800-numbers to ring into the same trunk group. Thisapplication differs from the traditional usage of 800-numbers, whichprovides a one-to-one association between 800-numbers and trunkgroups. Traditionally, each individual 800-number is assigned to its owntrunk group, often resulting in a large number of trunks. In such a situation,many of these trunks are often under-used, with the majority of calls beingrouted over trunks corresponding to the most commonly-called800–numbers. This arrangement requires a significant up-front charge forthe large number of required trunks, which are often used inefficiently.With DNIS, instead of having a single trunk group for each 800-number, acentral office assigns a group of trunks which can be used for multiple800–numbers. These trunks are universal and are selected as needed toaccommodate various 800-number calls. The flexibility of these trunkshelps protect against unequal trunk usage and provides a morecost–efficient method of call routing.

When an 800-number is dialed, a central office selects one of theuniversal DNIS trunks and dials the distant end (e.g., the PERCEPTION4000 system). The central office sends part of the dialed digit string to thePERCEPTION 4000 system, which is then matched in the systemdatabase as a programmed Listed Directory Number. At this point, the callcan be routed appropriately within the system. In the digit identificationprocedure. the system can correlate the received digits with DNIS nameidentification labels which have been programmed in the PERCEPTION4000 system database. These DNIS names will then appear at displaytelephones (or attendant consoles) whenever 800-number calls arereceived. This allows DNIS 800-number calls to be instantly identified andhandled appropriately.

After an 800-number is dialed and the required digits are received by thePERCEPTION 4000 system, the system will search the system databasefor a Listed Directory Number (LDN) which matches the received digits.The call can then be routed to the programmed destination associatedwith the LDN. A DNIS destination can be an ACD or UCD group pilotnumber, a hunt group pilot number, an attendant console/attendant group,an individual station, an announcement device, or a system night bell.Each DNIS 800-number can have up to three route choices for each of thesystem's four defined time zones.

Each 800-number can be assigned its own unique priority level so thatincoming calls to different 800-numbers will receive different calltreatments. This allows calls to certain 800-numbers to advance to the

front of an ACD queue for quicker call handling. Priority attributes that areassigned to individual 800-numbers through DNIS Priority Queuing enableeach of these numbers to receive its own type of treatment. DNIS PriorityQueuing can be used in an ACD environment in conjunction with the ACDPriority Queuing feature.

The ACD Priority Queuing feature prioritizes incoming ACD callsaccording to the trunk groups over which they arrive. Since DNIS800–numbers share a common trunk group, ACD prioritization does notspecify unique treatments for each 800-number. Instead, entire trunkgroups are prioritized.

The priority assignments of DNIS 800-numbers can be programmed tooverride any assigned ACD trunk group prioritization. DNIS priorityattributes are carried with an incoming 800-number call throughout callrouting. This allows a DNIS call to terminate at a non-ACD destination andbe transferred with its priority attributes intact. A DNIS call whichterminates at an attendant console or a non-ACD station will not take onthe priority of the attendant or station when call transferring or forwardingoccurs.

When assigning priority levels to 800-numbers, each number can beassigned an ACD priority level, a priority timer, an advanced ACD priority,and an overflow number. The ACD priority level indicates which level ofpriority a specific 800-number call will receive. Priority levels arenumbered from 1 to 16, with level 1 being the highest level. The prioritytimer indicates how long the call will wait at this priority level beforeadvancing to its next priority level. The advanced ACD priority specifiesthe advanced priority level (1 ~ 16). This is the final priority level which acall can reach before being overflowed. The overflow number indicates theoverflow destination of a call that has remained at the advanced prioritylevel for longer than the priority timer allows. The assignment of thesevarious priority attributes provides a great deal of flexibility when assigningthe priority treatments for different 800-numbers.

DNIS 800-number digit strings which are received by the PERCEPTION4000 system from a central office, can be correlated with DNIS names forincoming call identification purposes. DNIS names are assigned in thesystem database and can each consist of up to 14 alphanumericcharacters. Assigned names will be displayed at any display telephone orattendant console which receives a DNIS call. As an alternative, thereceived DNIS number, together with three digits of an assigned DNISname can be displayed at a receiving display telephone/attendant console.DNIS name/number information will be carried with a call throughout calloperations such as recall, call transfer, call forward, or conference.

System FeaturesPERCEPTION 4000 DIALED NUMBER IDENTIFICATION SERVICE

Information regarding the usage of DNIS 800-numbers and DNIS trunkscan be requested through ACD/MIS operations, as well as by using thePERCEPTION 4000 Traffic Measurement and Station Message DetailRecording (SMDR) features. By using specific ACD/MIS procedures, thenumber of calls to each DNIS number can be reported. SMDR will listDNIS numbers as incoming calls to the system. Traffic measurement willmeasure the amount of traffic on the DNIS trunk group. Individual DNIS800-number information is not specified in traffic measurement reports.

Direct Inward System Access (DISA) numbers can be assigned to DNIStrunk groups.

DNIS trunk groups must have their own assigned vacant number interceptposition, alternate vacant number intercept position, and received CO digitlength. DNIS trunks can be either analog, digital, or T1 types. Trunksignaling can be either DID, E&M, or Loop TIE signaling.

A DNIS call that is received by the PERCEPTION 4000 system and is notidentified in the system's database as a valid DNIS number, will be routedto the system's assigned vacant number intercept position. If this positionis unavailable, the call will be routed to the alternate vacant numberintercept position.

When routing a DNIS call to an off-premises destination, thePERCEPTION 4000 system will verify programmed trunk-to-trunkconnection and outdialing restriction information to ensure that the call ispermitted.

A DNIS call that is routed to an off-premises destination may not maintainall of its original characteristics, such as its DNIS name and its DNISqueuing priority level.

System FeaturesDID/CCSA PERCEPTION 4000

Direct Inward Dialing (DID) allows incoming calls on DID and CommonControl Switching Arrangement (CCSA) trunks to bypass the attendantand directly ring a station.

For an incoming call on a DID or CCSA trunk to bypass the attendant andreach a specific station, the last two to five digits of the trunk directorynumber must correspond with the station number. In order for the finaltranslated number to match an internal PBX station number, the systemcan add and/or delete up to five leading digits to/from the digits sent by thecentral office.

If an incoming DID or CCSA trunk call encounters a busy station, the callerwill receive busy tone. If a system flag is set in the system database toallow camp-on to all DID/CCSA trunk groups, then the caller will beautomatically camped-on to the called party. When Camp-on occurs, thecalling party will hear ringback tone and the called party will hear callwaiting tone. At this point, the called party can access the call by using theSwap feature.

DID calls to stations with Do Not Disturb registered will receive busy tone.

Both Automatic Call Distribution (ACD) and Uniform Call Distribution(UCD) pilot numbers can be accessed through DID numbers. Attendantconsole directory numbers and Station Hunting group pilot numbers canalso be reached through DID trunks.

System FeaturesPERCEPTION 4000 DIRECT INWARD ROUTING

Direct Inward Routing routes incoming trunk calls, other than Direct InwardDialing (DID), Direct Inward System Access (DISA), or incoming TIE trunkcalls, to different destinations based on the time of call arrival andattendant availability.

To define the time zones for call routing, the system administrator sets upa Time Based Inward Routing Table, which may have an entry for eachday of the week and an entry for holidays. Each entry can be divided intofour sections, corresponding to the four time zones. There are three routechoices associated with each time zone. The three route choices areconfigured hierarchically, with Route Choice #1 as the primary destination.Four sets of these route choices can be assigned to each trunk group orindividual trunk; one for each time zone. When a call is received, thesystem consults this Time Based Inward Routing Table to determine thetime zone that is currently in effect, and routes the call to the destinationthat corresponds to the effective time zone.

Each trunk group or individual trunk can have different routing instructionsfor each of the time zones. DISA trunks and incoming TIE trunks do notrequire routing definitions.

An incoming call will camp-on to a busy station that it has attempted toreach, if the station is not assigned with any Call Forward or StationHunting arrangement. The recipient of the camp-on will be notified by aCall Waiting tone and can retrieve the call by using the Swap feature.

A caller to a station that has Do Not Disturb activated will receive ringbacktone, but camp-on will not be allowed.

Incoming calls can be assigned to terminate at:� An attendant group.� An Automatic Call Distribution (ACD) group pilot.� External destinations via Speed Calling numbers, resulting in Trunk-to-

Trunk connections.� A Station Hunting group pilot.� An individual attendant.� An individual station.� An unassigned destination, so that an incoming trunk call will not be

System FeaturesDIRECT INWARD SYSTEM ACCESS PERCEPTION 4000

Direct Inward System Access (DISA) provides direct access to certainPERCEPTION 4000 features and facilities, such as trunks, paging, etc.,from a remote location. A caller outside the system must use a Dual-toneMulti-frequency (DTMF) sending telephone to access PERCEPTION 4000features. Features activated by hookflash cannot be accessed via DISA.The DISA trunk can be an incoming or bothway CO trunk or a DirectInward Dialing (DID)/Common Control Switching Arrangement (CCSA)trunk. Any number of CO trunks can be marked as DISA trunks. The DISAfeature, however, is not available for TIE trunks.

An outside caller can access DISA by dialing the listed directory numberassociated with the DISA trunk, waiting for internal dial tone when thesystem answers the call, entering any required security code, and thenwaiting for a second dial tone. After this procedure, the caller can accessinternal PBX features and outgoing facilities. The particular features andfacilities that can be accessed depends on the the Class of Service andcalling restrictions assigned to the seized DID/CCSA trunk.

An outside caller can call from a DID/CCSA trunk, by dialing the directorynumber associated with the DISA trunk and waiting for dial tone. Dial tonewill be provided only if the digits sent match one of the DISA directorynumbers that is listed in the DISA table associated with the DID/CCSAtrunk group. If dial tone sounds, the caller can then enter any requiredsecurity code and wait for a second dial tone. At this point, the caller canaccess internal PBX features and outgoing call facilities. The particularfeatures and facilities that can be accessed depends on the the Class ofService and calling restrictions assigned to the seized DISA trunk.

All trunk groups related to DISA must have a defined Class of Service(COS), Destination Restriction Level (DRL), Facility Restriction LevelProfile (FRLP), Queue Priority Level (QPL), and Dial 0 Destination .

A security code may be required for a caller to access the PBX. Thesecurity code is used to access any of the system's DISA trunks, whetherthey are CO or DID/CCSA related. Each defined security code has acorresponding ID code that is recorded in the system's Station MessageDetail Recording (SMDR) record, whenever the security code is used by astation user. This helps ensure the integrity of each security code. If aninvalid security code is entered, the system will provide a reorder tone andthe call will not be listed in the SMDR record.

If a DISA user makes a Trunk-to-Trunk call, two SMDR records will becreated—one for the incoming call, and the other for the outgoing call.

DISA trunks can only perform off-hook Camp-ons; on-hook Camp-ons arenot allowed. DISA calls to stations that have Do Not Disturb registered willreceive busy tone. Camp-on is not allowed in this situation.

Distinctive ringing is used to differentiate between the various types ofincoming calls. Immediate ringing is used to prevent lengthy delays prior tothe start of the ring cycle.

There are three distinctive ringing patterns. The selection of the correctringing pattern is based on the type of call origination. The three differentringing patterns coincide with the following call types:� Station-to-station calls.� Incoming calls from an external source, such as direct trunk calls or

trunk calls directed by an attendant.� Camp-on callbacks and recalls.

Emergency calls from a station to an attendant will ring as station calls.However, if programmed to do so, these calls will ring at full volume to thecalled attendant console.

Emergency Calling alerts an attendant in an emergency situation. Thereare four levels of emergency calling, which can each be assigned todifferent types of emergency calls. Each level is represented by a numberwhich follows the format of a directory number. The first two emergencycalling levels (1 and 2) have the highest answering priorities in the systemat any time. Levels 3 and 4 can be assigned as desired in the call priorityscheme. Emergency calls can be programmed to ring an individualattendant console or an attendant console group.

If programmed within the system database, emergency calls will ring thecalled attendant console at full volume. This will immediately alert theattendant of the emergency situation.

To initiate an emergency call, the station user simply dials an emergencycode.

When using a station hotline that is assigned for Emergency Calling only,the user simply picks up the handset or presses the hotline key.

Each level of emergency calls must be assigned its own emergency code,attendant answering priority, and answering destination. Each level alsohas its own assigned message which will display on an attendant consolewhen emergency calls are placed.

System FeaturesEQUAL ACCESS DIALING PERCEPTION 4000

Equal Access Dialing allows the PERCEPTION 4000 to accept longdistance carrier access codes (10XXX) which specify the desired carrierfor long distance calling.

After dialing the direct trunk access code, the station user has the optionof specifying a long distance carrier by entering an Other Common Carrier(OCC) access code (10XXX). After entering this code, the user can enterthe desired directory number. The directory number must follow theStandard North American Dialing Plan. If the station is allowed EqualAccess Dialing service, the call will be outpulsed. If the station is notallowed Equal Access service, reorder tone will be returned to the stationuser.

When Least Cost Routing (LCR) is used, the system will automaticallychoose a long distance carrier based on preprogrammed LCR information.In this case, the necessary Equal Access codes will be automaticallyinserted by the system so that the call can be placed over the necessarycarrier. Digits added through LCR can represent any 10XXX OCC accesscode.

System FeaturesGENERAL RECALL TREATMENTS PERCEPTION 4000

By generating recalls, the PERCEPTION 4000 automatically recovers callsthat would otherwise be lost or mishandled.

A recall occurs whenever a call:� Has been placed on Consultation Hold, and the holding station

becomes idle.� Has been placed on Call Hold, and has timed out.� Has been transferred to a ringing station, and has timed out.� Has been camp-on transferred to a busy station, and has timed out.� Has been parked, and has timed out.

There are two types of recalls: immediate recalls and delayed recalls. AConsultation Hold recall is an immediate recall. In this case, the held callimmediately recalls to a station once that station hangs up or becomesidle. The held call will recall to the line on which it was recently held. Adelayed recall includes a Call Hold recall, Call Park recall, UnscreenedTransfer recall, or Camp-on Transfer recall. In these situations, a recall willoccur after a predefined timeout period elapses. A Call Hold recall willrecall to the line on which it was recently held, while all other types ofdelayed recalls will ring the recalled station’s prime line.

The recalling party may be a station or a trunk. In either case, if the stationbeing recalled is idle, the recalling party will receive ringback tone, and therecalled station will ring. When the recalled station answers, the twoparties will be connected, and a normal two-way conversation will beestablished.

Recall timers are set in the system database. Internal call recalls willterminate at the station being recalled. Internal recalls will not beforwarded or routed to another destination. Trunk call recalls will follow therouting priorities as specified in their trunk group definition. A recall that isdirected to an unavailable attendant will be re-routed to a system nightbell.

Recalls are not affected by Call Forward, Do Not Disturb, or StationHunting operations. If any of these features are active at a recalled station,recalls will still terminate at that station.

The Intercept Treatments feature allows incoming calls to an invaliddestination to be rerouted to another destination. Intercept Treatment willalso be applied whenever a call is denied due to a station's assignedClass of Service, Facility Restriction Level, or Destination RestrictionLevel. The PERCEPTION 4000 system supports three types of InterceptTreatments—Tone Intercept, Voice Announcement Intercept, andAttendant Intercept.

Tone Intercept is the system's default intercept treatment. If this treatmentis used, a caller will hear reorder tone when a call cannot be completed.

Voice Announcement Intercept is optional and requires a customer-supplied announcement machine. If used, a caller will hear ringback tone,followed by a recorded voice message.

Attendant Intercept can be used to route calls to an attendant console.This type of intercept is effective only when the system is in the attendedmode. If selected, the caller will hear ringback tone while waiting in queuefor the attendant.

System FeaturesISDN PRIMARY RATE INTERFACE PERCEPTION 4000

The Integrated Services Digital Network (ISDN) is the multi-purpose digitalnetwork that represents the future of communications technology. TheISDN concept envisions a worldwide standard for voice and datatransmission, utilizing an open-system protocol that is independent of anyone vendor. The standards for this protocol are currently being establishedby the International Telegraph and Telephone Consultative Committee(CCITT).

ISDN utilizes two different types of channels for communication. Bearer(B-) channels provide the 64 Kbps digital communication links in thenetwork. Data (D-) channels carry call control and call-related informationfor the B-channels.

The PERCEPTION 4000 system supports the Integrated Services DigitalNetwork Primary Rate Interface (ISDN PRI). The Primary Rate Interfaceutilizes 23 B-channels which carry voice, data, image, etc. at 64 Kbps, andone D-channel which performs signaling and call control at 64 Kbps (23B+D transmission). The Primary Rate Interface is typically used to connecta PBX system to another PBX, to a host computer, and/or to longdistance/network services.

The ISDN Primary Rate Interface (PRI) is an option of the PERCEPTION4000 system, which comforms to the AT&T specification. This enablesISDN users to interface with AT&T ISDN services such as MEGACOM 800and the AT&T Software Defined Network. Through the use of adjunctequipment, the system can also interface with non-AT&T ISDN services,which are served by other (non-AT&T) types of central office and tollcenter equipment.

The ISDN features that are available to PERCEPTION 4000 system usescan be grouped into the following categories, which are each described inthe following paragraphs:� ISDN Network Service Access� Call-by-Call Service Selection� Call Identification� Non-Facility Associated Signaling

The PERCEPTION 4000 system supports the following services for ISDNvoice and modem data calls.

A group of ISDN PRI B-channels (channel group) can be flexibly assignedso that a channel can be utilized by various ISDN services on an as-needed basis. This eliminates the need for dedicated channelassignments, and provides a more thorough usage of ISDN PRI channels.The PERCEPTION 4000 system will automatically select an availablechannel within the channel group, on a call-by-call basis, and utilize thechannel for the required ISDN service (MEGACOM WATS, MULTIQUEST,etc.).

The various channels in an ISDN PRI channel group can be flexiblyassigned to different ISDN services through database programming. Eachservice is assigned a minimum and maximum level, indicating theminimum and maximum number of channels within the channel group thatcan be utilized for that particular service. This guarantees a minimum levelof access for that particular service. To further enhance the channel-sharing capability of the PERCEPTION 4000 system, minimum andmaximum levels can be altered for different times of the day (see Figure1). Such assignments accommodate applications which require thatcertain types of calls be placed at certain hours. For example, morechannels could be allocated for voice services during the day, and morechannels could be allocated for data services at night when data switchingis more likely to occur.

As an option, ISDN PRI channel groups can also be assigned to specificISDN services. In this case, each dedicated channel group will only beused for its assigned service and Call-by-Call Service Selection will notapply. As with non-dedicated channel groups, dedicated channel groupscan have assigned minimum and maximum levels to control the use ofchannels during certain time periods.

ISDN services (MEGACOM 800, etc.) can be flexibly assigned within a channel group to allow channels to be used by multiple services. Each ISDN service can have its own assigned minimum and maximum channel allocation levels.

Minimum and maximum channel allocation levels can be assigned differently for different time periods. In this example, the minimum level of channels to be allocated for a particular ISDN service is indicated by the size of the service's related channel grouping. For example, for Time Zone 1, a minimum level of four channels is allocated for MEGACOM 800 service.

ISDNPRI

An ISDN PRI interface can support either dedicated ISDN service, Call-by-call Service Selection, or both.

Each ISDN service is assigned to a specific trunk group (TGN). In the depicted application, trunk group 1 (TGN1) is assigned to MEGACOM 800 service, TGN2 is assigned to OUTWATS Band service, TGN3 is assigned to the AT&T Software Defined Network (SDN), and TGN4 is assigned to MEGACOM service.

Each TGN is associated with a specific channel group (through database programming). A TGN’s assigned ISDN service will utilize the channels in its associated channel group for voice and data calls.

Each channel group can contain up to 47 B-channels. These channels can all use the same D-channel for call control and signaling (Non-Facility Associated Signaling). In the depicted application, 23 B-channels (which are divided into three different channel groups) utilize the same D-channel (Channel Number 24).

Each ISDN service (TGN) can have programmed minimum and maximum channel allocation levels which determine how many channels will be used for that particular service. Different minimum/maximum levels can be programmed for each of the system’s four predefined time zones.

minimum/maximum channel allocation levels are noted for the Call-by-CallService Selection channel group. These assignments indicate how manychannels (minimum and maximum levels) will be used for each trunkgroup's associated service (Software Defined Network or MEGACOM).While all channels within dedicated service channel groups are assignedto the same ISDN service, minimum and maximum channel allocationlevels can be set to limit user access to channels during certain timeperiods. For example, a maximum level of channel groups can be set atzero to prevent any channels from being accessed.

As previously noted, ISDN B-channels can be used differently duringdifferent times of the day or week. The flexibility exists whether Call-by-Call Service Selection is used or if channel groups are dedicated tospecific ISDN services. The usage of each channel group is determinedby programming minimum and maximum channel allocation levels, and byconfiguring Service Usage Allocation Plans.

� Minimum Channel Allocation Level—Each ISDN PRI trunk group(which is assigned to a specific ISDN service) is assigned a minimumnumber of channels through system programming. This assignmentindicates the number of channels within the trunk group's associatedchannel group, which will always be available for the trunk group'sassigned ISDN service.

� Maximum Channel Allocation Level—Each ISDN PRI trunk group isalso assigned a maximum number of channels through systemprogramming. This figure determines the maximum number ofchannels within the trunk group's associated channel group, which canever be used for the trunk group's assigned ISDN service.

� Service Usage Allocation Plans—Each ISDN PRI channel groupcan utilize B-channels differently according to the time of day or day ofweek. Four separate allocation plans can be devised, with each planutilizing up to four different predefined system time zones. Eachchannel group is assigned to a specific allocation plan throughdatabase programming. Allocation plans incorporate minimum andmaximum channel allocation level settings so that channels can beused for certain ISDN services during certain time periods, whenincreased access is necessary.

ISDN PRI enables the transmission of helpful call identification informationbetween call parties. Display telephone users can be provided withcalling/called party identification information, enabling them to answer callsappropriately. Call identification information also enables calls to beidentified more clearly in call reports (e.g., SMDR). Calling/called partyidentification information is associated with a call until it is completed. Thisenables identification information to stay with a call throughout suchfeature operations as Call Pickup, Call Park, Call Hold, and Three-wayCalling.

The ISDN PRI trunk group can be designated through programming totransmit the telephone number of the calling party to the distant end. Thenumber that is presented will be either the station's assigned Direct InwardDialing (DID) directory number or the predefined Listed Directory Number(LDN) of the utilized PRI trunk group.

A classmarked station user can override the PRI trunk group transmissionof Calling Party Number (CPN) information, through the Calling PartyNumber Privacy Option feature. This enables the station user to enter afeature access code to prohibit transmission of CPN. Likewise, a PRI trunkgroup that has been programmed not to transmit CPN information can beinstructed to send CPN through the entrance of a separate feature accesscode. CPN Transmission or blockage can be controlled on a call-by-callbasis by entering the appropriate feature access code.

If desired, certain ISDN PRI trunk groups can be programmed so that theywill never send CPN information to the distant end. In this case, theprogrammed trunks are "barred" from sending CPN, and users cannotoverride this designation.

ISDN PRI trunk groups can be programmed to display incoming call partyidentification information. This information will appear at displaytelephones that are used in a PERCEPTION 4000 environment, enablingstation users to answer calls appropriately. Displayed identificationinformation can be of various types, depending on the programming ofeach trunk group. Each of these display options is depicted in Figure 3and is described as follows:

� Display Trunk Group Name: This option will display the name of theutilized trunk group, as programmed in the PERCEPTION 4000system database (e.g., MEGACOM). Trunk group names can consistof up to 14 characters.

� Display Called Party Number: This option will display the calledparty number of an incoming call. For DNIS calls, this will be the DNISnumber that is sent to the PERCEPTION 4000 system from theCentral Office. Each displayed called party number can consist of upto 13 characters and will be preceded by "#" for clarification.

� Display Calling Party Number: This option will display the number ofthe calling party. Each calling party number can consist of up to 14characters.

� Display DNIS Name: This option is available only for Dialed NumberIdentification Service (DNIS) trunk groups. When selected, this optionwill display the name of the DNIS trunk group which corresponds tothe DNIS number received from the central office. Each DNIS namecan consist of up to 14 characters.

When selected, this option willdisplay the calling party number in the left-hand area of the telephonedisplay, and the first three characters of the DNIS name in theright–hand display area. Each display can consist of up to 14characters and a blank space will always appear between calling partynumber and DNIS name information.

The B-channels on two different ISDN Primary Rate Interface (IPRI) circuitcards can be controlled by the same D-channel for ISDN signaling. Thispermits up to 47 B-channels to be controlled by the D-channel that isserviced by the ISDN Primary Rate Controller (IPRC) circuit card (seeFigure 4).

PERCEPTION 4000 station users can access ISDN PRI trunks to placeoutgoing voice or data calls, by using either of the following two methods:

� Direct Access: To access an ISDN PRI trunk group directly, a userdials the trunk group's associated trunk group access code. ThePERCEPTION 4000 system will then search for an availableB–channel in the trunk group' associated channel group. If a channelis available, the call will be placed and the user will hear ringback tone.If a channel is not available, the user will hear busy tone and can trythe call again later. Channel selection, based on trunk group/ISDNservice type is completely transparent to the ISDN user.

� Indirect Access: When placing a call via Least Cost Routing or withina network which utilizes either a Coordinated or Uniform NumberingPlan, an ISDN PRI trunk may be selected automatically by thePERCEPTION 4000 system. The automatic selection of an ISDN PRItrunk is determined by the programmed routing tables in the systemdatabase.

Incoming ISDN calls will be automatically routed by the PERCEPTION4000 system to destinations that have been assigned in the systemdatabase. Routing is based on the trunk group (ISDN service) over whicheach ISDN call arrives. Destinations for ISDN calls can be programmed asan ACD or UCD group pilot number, a hunt group pilot number, anattendant console/attendant group, an individual station, anannouncement device, or a system night bell. Different routing patternscan be assigned for each of the system's four defined time zones.

Each ISDN trunk is assigned through database programming to supportone of the following three termination modes. An ISDN trunk's definedtermination mode enables the PERCEPTION 4000 system to recognizethe necessary information to route an ISDN call appropriately.

System FeaturesLEAST COST ROUTING PERCEPTION 4000

When programmed correctly, Least Cost Routing (LCR) provides a meansof utilizing the most economical calling routes. LCR can be programmedso that outgoing calls are routed over specific trunks during specific timesof the day, during the week, or on holidays. When used, the system willattempt to place a call over one of the least expensive routes. Only if theseroutes are unavailable, will more expensive routes be accessed. If desired,a warning tone can be programmed to sound whenever an expensiveroute is about to be accessed. Individual stations can also be preventedfrom accessing the more expensive routes, through programmed stationrestrictions.

When LCR is used, the system processes calls by means of Network DigitAnalysis, Time Based Routing, Route Selection, Queuing, and DigitTranslation. When the database has been configured properly, LCR willroute calls in the most economical available manner.

Network Digit Analysis examines a dialed number digit-by-digit,determines the end of dialing, and divides the dialed digits into categories.As long as the number conforms to the dialing rules, the call is allowed tocontinue. As soon as enough digits are collected, the LCR route patternselection process will begin.

The end of dialing can be detected by two methods. One of these methodsinvolves the system's examination of digits as they are entered. In thiscase, the system examines the entered digits and establishes the totalnumber of digits that needs to be entered. The second method involvesthe use of a timeout period. In this case, the system automatically waits fora designated time period after each digit is dialed. If no additional digitsare dialed before this time period elapses, the system assumes thatdialing is complete. When this second method is used, a pound (#) signcan be entered to inform the system of dialing completion.

Time Based Routing uses programmed time zone tables to determine thespecific routing table to be used for a call. The system accomplishes thisby first determining the currently-active time zone table, based on thecurrent time and day of the week. The system then compares the enteredcall digits to the codes that have been assigned in the currently-active timezone table. The call will then be routed over the appropriate route.

After a routing table is selected, the system selects a route within thattable. Each route choice defines a trunk group, a long distance carrier(optional), a Facility Restriction Level (FRL), and digit translationinstructions (optional). Up to eight different routes may be defined,beginning with the most economical and ending with the most expensive.If a more expensive route is selected, the user can be provided with anexpensive route warning tone.

In order for a caller to use a specific route, that route's assigned FRL mustbe one of the FRLs (routes) defined in the caller’s Facility Restriction LevelProfile (FRLP).

System FeaturesPERCEPTION 4000 LEAST COST ROUTING

LCR Queuing is dependent on the calling station’s or trunk's QueuingPriority Level (QPL). Each station, attendant console, data station, andTIE/DISA trunk in the system is assigned a QPL ranging from 1 to 8, with1 having the highest priority, and 8 having the lowest priority.

A new call is placed in the queue according to the caller’s QPL. If a highpriority call attempts to camp-on to a queue that is full, the system willremove the last call in the queue to accommodate the high priority call. Formultiple calls having the same QPL, calls will be placed in queue on aFirst-in/First-out (FIFO) basis.

After the route selection program has exhausted all possibilities for routinga call, the system will initiate Camp-on. If a trunk becomes idle at any timeduring this sequence, the call will be processed immediately.

LCR Queuing is only used if the QPL flag is set in the system database. Ifthis designation is not made, then calls will be queued on a FIFO basis.

Digit Translation modifies the dialed digits in order for a call to be sentthrough central offices or other PBX systems. Digit Translation isprogrammed in the system database and allows the system toautomatically perform any of the following functions:� Add an Equal Access Carrier code.� Add, delete, replace, or retain the toll prefix.� Add, delete, or retain the area code.� Define prefix digit strings.� Define suffix digit strings.

To access LCR, a station user simply obtains internal dial tone, enters anLCR access code, and dials the desired destination number.

Each station, trunk, or attendant that can originate calls must be assignedwith a Facility Restriction Level Profile (FRLP) and a Queue Priority Level(QPL). LCR calls can be restricted by both Destination Restriction Level(DRL) and FRL, or by FRL alone.

A caller who places an emergency call, a hotline call, or a call that isforwarded to an off-premises destination, will not receive a warning tone ifthe call is being routed over a more expensive route.

The LCR access code can be included as part of a Speed Calling numbersequence.

The system allows specific Direct Inward Dialing (DID) or Common ControlSwitching Arrangement (CCSA) numbers to be assigned as listeddirectory numbers. An incoming DID or CCSA call to one of thesenumbers will be automatically intercepted by an attendant or otherspecified answering position.

If the incoming numbers match any of those that are listed in the trunkgroup’s Listed Directory Number (LDN) table, the system will sendringback tone and will connect the caller to the specified attendant oranswering position. If the LDN destination is busy, the caller will hear busytone. If a system flag has been set in the system database for allDID/CCSA trunk groups to receive Camp-on, then the caller will receiveringback tone and the called station will hear call waiting tone. At thispoint, the called party can access the new call by using the Swap feature.

LDN calls receive the same routing options as normal CO trunks.

LDN route choices can be defined by any of the four time zones that aresupported by the system.

Each DID/CCSA trunk group can be assigned to one LDN table, which candefine up to 32 DID/CCSA LDNs. Each LDN is associated with a specificrouting destination. The routing destination can vary according to the timeof day or day of week, by assigning time of day/day of week schedulechanges in the system database.

The PERCEPTION 4000 system provides a variety of methods for leavingand receiving messages. Callback Messaging allows messages to be sentand received via feature access key or code, and is available to all stationtypes. PERCEPTION 4000 proprietary 20-key digital telephones(HDT2020SD) can also send and receive predefined text messages viathe telephone's soft keys and Liquid Crystal Display. Additionally, the useof a system-connected voice mail application processor is available tothose stations with associated voice mailboxes.

PERCEPTION 4000 HDT2020SD telephones can receive up to four textand/or callback messages plus one voice mail notification. All other stationtypes can receive one callback message plus one voice mail notification. Avoice mail notification represents any number of individual messages thathave been left in a voice mailbox.

Any telephone in the PERCEPTION 4000 system can send callbackmessages, as long as the receiving station has the ability to receivemessages. A callback message can be registered either by pressing apredefined Message Waiting key (digital and electronic telephones), or byentering a Message Waiting access code.

When a message is left at a station, that station's Message Waiting keyLED or Message Waiting light will light to indicate the waiting message.The LED/light will also light when a message has been left in the station'svoice mailbox. Standard analog telephones with or without a messagewaiting light will also receive stutter dial tone to indicate that a message iswaiting. To retrieve a message, a station user can simply press theMessage Waiting key (or enter a Message Waiting access code if using astandard telephone). If a voice mail message has been registered, thesystem will automatically route the user to the voice mail system. At thispoint, the user can enter his/her mailbox and retrieve the voice mailmessage(s). After voice mail messages have been retrieved, the user canhang up and then press the Message Waiting key again (or enter theMessage Waiting access code again) to call back any party that registereda callback message at the telephone.

PERCEPTION 4000 HDT2020SD users also have the option of scrollingthrough messages left at their telephone. By pressing the MSG soft key,message indications will appear on the telephone's display, allowing theuser to skip, cancel, or return each message. Callback messages will notethe name, extension, time, and number of call attempts associated witheach message. A voice mail indication will note that messages exist in thestation's mailbox. A voice mail message display indication can becanceled through soft key operation; however, each individual voice mailmessage must be canceled from within the voice mail system.

Once all messages have been successfully retrieved or canceled from atelephone, the system will extinguish the telephone's Message WaitingLED or light.

System FeaturesPERCEPTION 4000 MULTIPLE CONSOLE OPERATION

Attendant consoles in the PERCEPTION 4000 system are assigned toattendant console groups. This allows incoming calls to be shared amongvarious attendants. If desired, certain types of trunk calls can be assignedto be routed to specific consoles in an attendant group.

The PERCEPTION 4000 system can have up to 30 assigned attendantconsoles, which can be assigned, in any arrangement, to attendantconsole groups. Each attendant console can be assigned to only oneattendant console group. A directory number can be assigned to theattendant console group as well as to each individual attendant. Eachconsole that is part of an attendant console group, shares the call loadpresented to that group's directory number.

In a multiple console environment, a station user can access an attendantgroup by dialing the group's directory number. The call will be routed to thenext available attendant in the group. A station user can also dial a specificattendant console by dialing the console's individual directory number.

As an alternative to dialing an attendant or attendant group directorynumber, a station user can enter the Universal Attendant access code("0"). When entering this code, the call will be automatically routed to theattendant group that is assigned to the calling station in the systemdatabase.

Different types of incoming calls can be assigned to specific attendantconsoles or attendant groups, through database programming. Calls thatarrive on certain trunks can also be assigned to be routed to an alternativeanswering point.

An unanswered incoming trunk call that is transferred from an attendant toan internal destination, will recall the attendant. If the transferred call wasserved by an available attendant within an attendant group, the call willrecall either the next available console in the group, or the transferringattendant, as determined by database programming.

When a member of an attendant group is placed in Position Busy mode,attendant group calls will be distributed among the other consoles withinthe group. Calls to an individual attendant console that is in Position Busymode, will be routed according to the console's internal call routingchoices or according to the incoming trunk's routing choices.

Incoming trunk or station calls can be transferred to members of the sameattendant group or to members of different attendant groups.

The Outdialing Restrictions feature allows each station to be individuallydenied from placing certain types of outgoing calls.

Possible restrictions are area code restriction, area/office code restriction,exceptional allowance and exceptional denial, international restriction, andtoll restriction.

This allows or denies calls to specific area codes.

This allows or denies calls to specific office codes within specified areacodes.

These are defined for each Destination Restriction Level (DRL)/TrunkRestriction Group (TRG) combination, and are used to provide exceptionsto the normal restrictions provided by area code restriction, area/officecode restriction, and other restriction types.

This allows or denies calls to specific country codes.

This denies calls to destinations that are outside the toll-free calling zonethat applies to the trunk group being used.

When a station user dials a destination number (using either Least CostRouting or Direct Trunk Group Access), the system will analyze theentered digits and check the appropriate restriction table(s). If the call isallowed, the user will be connected to a trunk, and the call can becompleted. If the call is denied, the user will receive reorder tone or otherintercept treatment, and the call will not be completed.

The following information must be assigned in the system database beforeany outgoing call can be placed:� Each station must be assigned a Destination Restriction Level (DRL).� Each trunk group must be assigned to a Trunk Restriction Group

(TRG) and must also be assigned a “home area code” to which thetrunk group terminates.

� The relationship between the DRL and TRG must be defined, and theoutgoing capability must be allowed by DRL/TRG.

� The ability for a station to originate calls and to access at least onetrunk group must be defined in the station's Class of Service (COS).

Calls placed via Autodial, Last Number Redial, Save and Repeat, orSpeed Calling are analyzed by Outdialing Restrictions. The system alsoanalyzes a station's COS to determine whether or not calls placed viaDirect Trunk Group Access are allowed.

System FeaturesPERCEPTION 4000 NETWORKING PERCEPTION 4000

A PERCEPTION 4000 system can network with other remotely-locatedsystems via analog or digital trunking. Systems that are part of aPERCEPTION 4000 network can be other PERCEPTION 4000 systems,STRATA or PERCEPTIONe&ex systems, and/or other compatible PBXsystems.

Network arrangements can be simple or highly sophisticated. A basicnetworking arrangement uses TIE trunks and Cut-through Dialing,enabling users to access stations in other networked systems by dialingtrunk access codes. More sophisticated networks can uti l ize aCoordinated Numbering Plan (CNP) or Uniform Numbering Plan (UNP) toprovide easy and convenient dialing between networked systems. APERCEPTION 4000 system can also be used as a main, satellite, ortributary system within a very large network environment, such as anElectronic Tandem Network.

A networking arrangement utilizing Cut-through Dialing requires TIE trunksto connect the networked systems. To call a station in another system, astation user simply dials the trunk access code for the trunk group neededto route the call, and then dials the desired station number. If a networkcontains tandem switches for call routing, multiple dialing steps may berequired. In such an arrangement, callers wait for dial tone after accessingeach system that must be accessed to route a call. After receiving dialtone, additional digits can be dialed.

In a networking arrangement that utilizes a Coordinated Numbering Plan(CNP), the station numbering plans of all networked systems arecoordinated with each other. Station directory numbers are assigned sothat all numbers contain the same amount of digits, and so that no onedirectory number is duplicated. The first one or two digits of each stationdirectory number represent the "steering digits" that are used to select theappropriate TIE trunk group for call routing. Each steering digit sequenceis assigned to a certain trunk group, so that whenever a directory numbercontaining the sequence is dialed, the system will automatically route thecall over a trunk within the required trunk group. After selecting the propertrunk, the system sends the entire station directory number to the distantswitch. At this point, the call is either routed to an internal station or, if theswitch is a tandem switch, is routed back out over the network.

The station numbering plan of each networked system must becoordinated with the numbering plans of other systems in the network.Each unique steering digit sequence can be assigned to only one specifictrunk group. This ensures that the trunk group will be selected wheneverthat particular digit sequence is dialed. Each trunk group, however, canhave multiple steering digit sequences assigned to it, allowing a singletrunk group to be used to route calls to various locations.

CNP provides completely transparent call routing to station users. There isno need to enter specific trunk access codes, since they are embedded in

station directory numbers. Additionally, there is no need to performmultiple dialing steps when calls are routed through tandem switches.

A Uniform Numbering Plan (UNP) routes inter-system station calls bymeans of Least Cost Routing (LCR). Different switches within the samenetwork do not have to share the same numbering plan for stationnumbers. Instead, numbers can be translated by the PERCEPTION 4000system to interface with the other networked switches. Digits can be addedor deleted to achieve appropriate dialing addresses. Each switch isidentified by a unique Location Code, which is used to inform the systemwhich routing patterns may be used to route calls, and which digits need tobe translated.

To make an inter-system station call via UNP, a caller enters a NetworkAccess Code (1 to 3 digits) and dials the desired network number. ThePERCEPTION 4000 system then checks its own Location Code by usingNetwork Digit Analysis and, if allowed, the call is sent to the distant end. Ifan invalid access code has been entered, the calling party will hearreorder tone. If all trunks are busy, the call will be camped-on to the TIEtrunk group or will be routed as assigned in the system database.

Forced Account Code entry is not required for CNP or UNP calls.

CNP and UNP calls are not checked by Outdialing Restrictions; however, ifdesired, UNP can be restricted by Facility Restriction Level (FRL) andFacility Restriction Level Profile (FRLP) assignments.

UNP Location Codes are recorded in the Station Message DetailRecording (SMDR) records.

System FeaturesPOWER FAILURE TRANSFER PERCEPTION 4000

The Power Failure Transfer feature automatically connects selected trunksto selected standard telephones so that calls can still be initiated andreceived in the event of a power failure. When power is restored, systemdata will reload and Power Failure stations and trunks will automatically bereturned to normal service.

Multiple Power Failure Transfer Units (PFTUs) can be used toaccommodate a desired number of reserved Power Failure stations. Either500 (pulse) and/or 2500 (tone) type telephones can be used as PowerFailure stations.

When the PFTU detects a loss of power, it automatically connects bothwayCO trunks to selected analog stations, thereby bypassing the PBX. Theseanalog stations then have the capacity to place and receive calls during afacility power failure.

When one of these selected stations is taken off-hook, the user will hearcentral office dial tone instead of PBX dial tone. The user can then initiatean outgoing call simply by dialing the destination number. A Least CostRouting (LCR) access code or direct trunk group access code does notneed to be entered.

System FeaturesPERCEPTION 4000 REDUNDANCY

The PERCEPTION 4000 system can be configured for redundancy toprovide backup hardware units in case of a component failure. Systemscan be set so that a transfer to backup components wil l occurautomatically whenever a malfunction occurs.

A redundant system has both shelves of the Modular Common ControlUnit (MCCU) occupied by common control cards and power supply units.Ordinary system operation utilizes those components located in the topMCCU shelf (CCA). In the event of a component malfunction, operation istransferred to those units located in the backup bottom shelf (CCB).

Redundancy can also be applied to Modular Line/Trunk Units (MLTU),through the provision of additional Line/Trunk Power Supply Units(LPWUs) and Line/Trunk Building Units (LBIUs). This arrangementprovides a backup power supply for line/trunk operations, and alsomaintains MLTU communication with the MCCU.

A system's backup components can be set to operate on either a hot orcold standby basis. In a hot standby arrangement, the "Mode" switch onthe system operation panel (located on the Top Unit of the System Stack)is set to "AUTO." In this case, a transfer of system control occursautomatically if there is a component failure in CCA. A failure in an MLTUpower supply unit or LBIU will automatically activate the operation of theMLTU backup components. The transfer of system control from the activeside to the standby side takes about 35 seconds, depending on systemconfiguration. During this time, existing two-way conversations and ringingcalls will be retained; however, new calls cannot be initiated.

In a cold standby arrangement, the PERCEPTION 4000 is set foroperation on one system side—either CCA or CCB. The "Mode" switch onthe system operation panel can be set for either "A" or "B" operation.

The cold standby option allows a system manager to do maintenance onone system side while the other side is in operation. While mostmaintenance and administrative functions can be performed while thesystem is operating, certain situations may render that one system side bedeactivated while work is being performed.

During the brief period when a transfer of system control is beingperformed, dial tone will not be available, feature access will not beallowed, and only the following types of calls will be retained:� On-going two-way conversations� Ringing calls� Recalls

PERCEPTION 4000 Maintenance and Administration (M&A) functions canbe performed from a remote location. This is particularly beneficial forcustomers with multiple PBX sites, since M&A tasks can be performedfrom a single location.

To perform M&A functions from a remote location, the technician can diala dedicated modem. Modem access can also be achieved through a calltransfer to the modem location through standard inward routingprocedures. After accessing the modem, the remote M&A terminal has thesame capabilities of a local terminal. Just as when using a local console,password entries are required to enter the system.

The communication protocol for remote M&A is asynchronous, full-duplex,odd/even/no parity (depending on configuration) with a transmission speedof 300 to 9600 BPS.

The PERCEPTION 4000 system must have an associated customer-provided automatic answer modem. The remote M&A user must have anASCII terminal.

System FeaturesSPEED CALLING PERCEPTION 4000

Speed Calling allows a station user to call selected numbers by means ofan abbreviated dialing sequence. The system supports two types of SpeedCalling—System Speed Calling and Group Speed Calling. Both attendantsand station users can access System Speed Calling, while Group SpeedCalling is reserved for station members that belong to designated groups.Speed Calling capabilities can also be assigned to TIE and DISA trunks,as well as to data stations. Refer to the Data Speed Calling data featurefor information regarding Speed Calling access from data stations.

Both System Speed Calling and Group Speed Calling can addressinternal and external voice/data destinations. Both Speed Calling typescontain lists of number sequences that are automatically dialed whenevertheir representative Speed Calling "index number" is dialed. The indexnumber represents the location of a number sequence within the SpeedCalling list. Up to 1,000 numbers can be assigned to the System SpeedCalling list, while each Group Speed Calling list may contain up to 10numbers.

To access System Speed Calling, the station user presses the SystemSpeed Calling access key (SYSD) or enters the System Speed Callingaccess code, and then enters the 3-digit index number for the desireddestination. Display stations will indicate the entered index number.

Attendants can access System Speed Calling to perform Non-delayedStraightforward Completion for a restricted station. To dial a number in theSystem Speed Calling list, the attendant presses the System SpeedCalling (SYSD) access key or enters the System Speed Calling accesscode, and then enters the index number for the desired destination. Afterdialing is complete, the attendant can pass the call to the requestingstation user.

To access Group Speed Calling, the station user presses the GroupSpeed Calling (SC-G) key or enters the Group Speed Calling accesscode, and then enters the 1-digit index number for the desired destination.Display telephones will indicate the entered index number.

Speed Calling is not available during Power Failure Transfer. However,since all Speed Calling numbers are stored on the hard disk, they will beavailable once power is restored.

A Speed Calling number may be programmed to contain only the leadingdigits for the desired destination number. In such cases, the systemexpects the calling party to dial the remaining digits from the dialpad.

Account Codes may be used or required when Speed Calling is used, justas with any other type of external call origination.

Any trunk restrictions assigned through a station's Class of Service, orthrough Trunk Group Access Control, apply to Speed Calling operation.

Speed Calling may be directed to use the Least Cost Routing (LCR)

The System Shutdown Procedure prevents any physical damage to thePERCEPTION 4000 system that may be caused by extremetemperatures. The procedure is automatically initiated by the system whenan overheat condition occurs. A shutdown will also occur whenever apermanent power failure or switchover (and/or IPL) failure is detected.

The system contains six heat sensors that continually measure systemtemperature. Two of these sensors regulate fan activation anddeactivation; two regulate the activation of a temperature alarm; and tworegulate a system shutdown. When the temperature inside the systemcabinet reaches 185° F (85° C), the system will automatically shut down.As soon as a system shutdown occurs, the system's disk head isprotected in order to prevent the disk drives from damage and to protectthe integrity of the program or data on disk storage. Power Failure Transferfacilities, if utilized, will then be activated in order to maintain the minimumservice needed.

A system shutdown will also occur when a power failure condition isdetected. The system is considered to be experiencing a power failurecondition when the normal operation DC voltage drops below -38V or risesabove -57V. Upon reaching either of these voltage levels, the system willshut down immediately. Power Failure Transfer facilities will then beactivated.

Each Power Failure Transfer Unit (PFTU) provides immediate connectionof up to eight preselected trunk lines to designated standard telephones.Multiple PFTUs can be used to support the desired number of reservetelephones.

The T1/DS-1 Interface, operating at 1.544 MBPS, provides thePERCEPTION 4000 with 24 multiplexed, 64 KBPS, digital channels forsimultaneous two-way voice or data transmission. In order to provide theabove capabilities, the PERCEPTION 4000 T1/DS-1 digital trunk interfacecomplies with requirements defined by the industry for the Digital SignalLevel One (DS-1) service. It also provides an economical alternative forany networking environment by replacing the numerous TIE trunks thatwould otherwise be necessary for connection. Additionally, the T1/DS-1Interface gives the PERCEPTION 4000 the capability to connect to:� A digital central office.� An analog central office via a channel bank.� Another PERCEPTION 4000 system.� A PBX from a different manufacturer, which provides the standard

T1/DS-1 interface.

When connected to a central office or a public network, a Channel ServiceUnit (CSU), which is usually line-powered by the network, is required. ACSU is also required when connecting the PERCEPTION 4000 system toanother PBX system if the connecting distance is more than 650 feet. Thisapplies when connecting to either another PERCEPTION 4000 system oranother PBX type. If the connecting distance is less than 650 feet, a CSUis not required when connecting to another PERCEPTION 4000 system. Ifanother type of PBX is used, a CSU may or may not be required,depending on the type of PBX used.

The PERCEPTION 4000 T1/DS-1 Interface supports two types of clocksynchronization. The system's internal clock can act as a master clockreference for a private network, or the system can act as a slave to a clockreference provided by either the public or a private network. Wheneverthere is more than one T1/DS-1 trunk installed in the system, only onetrunk will provide the clock synchronization signal.

T1/DS-1 Interface channels are accessed as with any other trunk. Theindividual channels are multiplexed together for transmission, sent out overthe public or a private network, and then separated back into distinctchannels at the distant end. Different facilities such as CO, DID, FX, TIE,or WATS trunks can be emulated on the T1/DS-1 interface.

System FeaturesTIME OF DAY/DAY OF WEEK SCHEDULE CHANGES PERCEPTION 4000

To achieve maximum efficiency, calls may be routed to differentdestinations based on the times that they arrive. The Direct InwardRouting feature of the PERCEPTION 4000 allows incoming calls to berouted to different places based on time of day, day of week, or holidays.Each day of the week can be segmented into four unique time zones; eachwith a different inward routing pattern. The assigned time zones also applyto Least Cost Routing operation and Class of Service assignments.

Inward routing patterns are specified in the system database throughMaintenance and Administration (M&A) commands. Schedulespecifications are recorded in the system's Time Based Inward RoutingTable. This table has an entry for each day of the week and an entry forholidays. Each day can be divided into up to four sections, which eachcorresponds to a unique time zone. Each time zone may contain adifferent set of routing instructions.

When a call arrives, the system checks the Time Based Inward RoutingTable to determine the time zone that is currently in effect. The call willthen be routed to the destination that corresponds to that time zone.

Based on the time of day, day of week, or holiday, calls to certain directorynumbers (Listed Directory Numbers) may also receive time-based routing.Through alterations to the Time Based Routing Table, the system willapply intercept treatment when these calls arrive.

The Time Based Routing Table is continually checked by thePERCEPTION 4000 whenever a call is placed via Least Cost Routing.This allows the system to route calls over different routes in accordancewith time-based trunk cost reductions.

A device's Class of Service assignment can be programmed to varyaccording to the time of day, day of week, or holiday. This allowsindividuals' special calling requirements to be accommodated.

The PERCEPTION 4000 system is compatible with a variety of telephonetypes. These devices include proprietary PERCEPTION 4000 digitaltelephones (the HDT2010S and HDT2020SD), Toshiba electronictelephones, and Toshiba 2000 series DKT digital telephones. Standardsingle-line, 500/2500 analog telephones can also be used with the system.

The ability to use these various telephone types enables Toshibatelephone system customers to upgrade to the PERCEPTION 4000system and still retain their existing telephones. This may result in aconsiderable cost savings since such equipment does not need to bereplaced. The variety of system-compatible telephones is also veryconvenient when constructing Automatic Call Distribution groups. Whilethe HDT2020SD telephone is recommended for ACD supervisor positions,(because of its high-level display capabilities), any system-compatibletelephone can serve as an ACD agent position.

The specific electronic and DKT telephone models that are compatiblewith the PERCEPTION 4000 system are noted in Table 1. This table alsoindicates which data interface units can be used with the system. Asmentioned, the PERCEPTION 4000 system also has its own proprietarytelephones (not listed in Table 1).

System FeaturesTOSHIBA TELEPHONE COMPATIBILITY PERCEPTION 4000

Specific physical differences between the PERCEPTION 4000 digitaltelephones and the Toshiba electronic/digital telephones are often relatedto feature operational differences or feature availability. The primarydifferences between these telephone types are noted as follows:

SOFT KEY OPERATIONPERCEPTION 4000 HDT2020SD digital telephones contain sixstate–driven soft keys. The functions of these keys vary according to thecurrent state of the telephone and the current state of the connectedstation or trunk. PERCEPTION 4000 HDT2010S digital telephones andToshiba electronic/DKT digital telephones do not contain soft keys. Thesetelephones, however, can be used to access some soft-key relatedfeatures, through flexible key operation.

LIQUID CRYSTAL DISPLAYThe PERCEPTION 4000 HDT2020SD digital telephone contains a 4x30character Liquid Crystal Display (LCD), which is used to convey a largeamount of information to the station user. The display area indicates thecurrent time and date, calling/called party information, call duration figures,advisory and predefined text messages, and soft key labels. ThePERCEPTION 4000 HDT2010S digital telephone does not contain adisplay area. Toshiba electronic and DKT digital telephones are availablein various models with and without displays. Those telephones whichcontain a display have a smaller display area than the HDT2020SD (2x16character), and typically indicate a condensed version of the informationthat is displayed on the HDT2020SD telephone.

LED INDICATIONSPERCEPTION 4000 HDT2010S/HDT2020SD digital telephones andToshiba DKT digital telephones all contain dual-color (red/green) LEDs toindicate feature and line usage. Toshiba electronic telephones containsingle–color LEDs. LED color schemes and flash rates that apply tofeatures may vary between telephones, due to these physical differences.LED operation for the various telephone types has been carefullyengineered to covey necessary call information to the station user.

FIXED KEYSThe PERCEPTION 400 HDT2010S and HDT2020SD digital telephones,as well as Toshiba DKT digital telephones each contain eight fixed keys forcommonly-used station features. These keys are Speaker, Microphone,Volume Up/Down Control, Message Waiting, Conference/Transfer, LastNumber Redial, and Hold. Toshiba electronic telephones contain four fixedkeys: Speaker, Microphone, Conference/Transfer, and Hold.

FLEXIBLE KEYSThe PERCEPTION 4000 HDT2020SD telephones contain 20 flexible keyswhich can be programmed for line or feature access. The HDT2010Stelephone contains ten flexible keys. Toshiba electronic and digitaltelephones are available in various display/non-display models whichcontain either ten or 20 flexible keys.MODE, PAGE, AND SCROLL KEYS


1-79


Toshiba electronic and DKT digital display telephones each contain threekeys, located near the display, which are labeled Mode, Page, and Scroll.These keys are used in STRATA and PERCEPTIONe&ex systemenvironments to prompt various types of display information. These keyshave no function in a PERCEPTION 4000 system environment.

The various telephones that can be used with the PERCEPTION 4000system require different circuit cards. PERCEPTION 4000 digitalHDT2010S/HDT2020SD telephones (with or without Integrated DataInterface Units) require a single port of a 16-port Digital Service TerminalInterface (DSTI) card. Toshiba electronic telephones each utilize one portof an 8-port Electronic Telephone Interface (EKTI) card. Toshiba DKTdigital telephones each utilize one port of an 8-port Digital TelephoneInterface (DKTI) card. Standard 500/2500 telephones each utilize one portof a 16–port Basic Standard Telephone Interface (BSTI) card. The BSTIcard can also support other types of equipment which require an analogline interface, such as dictation machines and answer bell devices.



System Features

TRAFFIC MEASUREMENT PERCEPTION 4000

The Traffic Measurement feature provides the statistics needed to monitorthe effectiveness of the system and to determine whether the system isover-configured, under-configured, or of proper traffic balance. Suchmeasurements involve a number of parameters, including call attempts,completed calls, traffic intensity, congestion, and average holding time.Feature initialization, activation, and deactivation are accomplished viaMaintenance and Administration (M&A) commands.

There are 16 time zones in the system, with each time zone being onehour long. Measurements are activated and deactivated based on thepredefined time zones. Beginning and ending times of a time zone mustbe at hourly quarters (e.g., 9:00, 9:15, 9:30, or 9:45). Overlapping betweenthe time zones is not allowed.

The use of system Traffic Measurement and reporting involves theprogrammed definition of traffic monitoring information, actual trafficmeasuring, and the reporting of measured information.

Before traffic measuring can occur or reports can be generated, thesystem administrator must define monitoring information in the systemdatabase. Through M&A commands, the administrator can define timezones, measurement objects, measurement periods, and repor tspecifications.

Once assigned by the system administrator, the activities of any or all ofthe following items can be simultaneously measured by the system. � Attendant group� Bothway trunk group� DID trunk group� Incoming trunk group� Outgoing trunk group� System total traffic

Measurement statistics are compiled at the end of each specified timeperiod or as requested on a real-time basis. Once reports have beenoutput, the statistics in the report buffer are cleared. However, if reportsare requested on-demand by a system administrator, the statistics will beretained in the buffer and the normal report generation schedule will notbe affected.

System FeaturesPERCEPTION 4000 TRUNK HUNTING

When an outgoing trunk group is accessed either directly or via Least CostRouting (LCR), the system automatically searches for an idle trunk withinthat group. A caller will receive busy tone only when all trunks within thecalled trunk group are busy. Trunk Hunting applies to data calls as well asvoice calls.

The PERCEPTION 4000 supports two hunting methods:� Distributed Hunting—the system begins hunting from the last hunted

trunk and searches through the list in a circular manner until a trunk islocated.

� Terminal Hunting—the system begins hunting at the first trunkmember and searches through the list to the last trunk member in thelinear sequence. The first idle trunk in the linear sequence will beseized, with the search ending at the last member.

Trunk groups, trunk member order, and trunk hunting methods are definedin the system database. Feature operation is automatic once allparameters are defined.

Trunk Hunting begins when a trunk group access code is entered, eitherdirectly or by Speed Calling, and all restrictions have been checked. If anidle trunk is found, then the trunk is seized and Trunk Hunting ends.However, if no trunk in the accessed group is available, busy tone will beprovided. The caller may either hang up to disconnect the call, wait to hearCamp-on success tone, or manually activate the Camp-on feature tocamp-on to the desired trunk group. Once Camp-on is successfullyactivated, the call will enter the trunk group waiting queue.

Once a routing table is identified, the first trunk group that is listed in therouting table will be accessed, and Trunk Hunting will begin. Hunting willend when an idle trunk is located. If all trunks are busy within the trunkgroup, the system will begin to search the next trunk group listed in thesame routing table.

System FeaturesUNIFORM CALL DISTRIBUTION PERCEPTION 4000

Uniform Call Distribution (UCD) provides a means of distributing a largenumber of calls to a group of stations (UCD group members). Whenever aUCD group pilot number is called or when a call is routed to a UCD groupthrough Direct Inward Routing, the system will route the call to the nextavailable group member.

Each UCD group is identified by its UCD group pilot number. Eachindividual UCD group member station is identified by its own extensionnumber.

Each UCD group has a queue in which incoming UCD calls wait for anavailable group member. As the members become available, the calls inqueue are served on a First-in/First-out (FIFO) basis. If programmed, thecalls can overflow to a UCD or Automatic Call Distribution (ACD) group ifthey have not been served within a predefined time interval. While waitingin queue, the callers may hear recorded announcements and/or music-on-hold, as programmed in the system database.

Calls are distributed to UCD group members on a Next Available-Firstbasis. When a call arrives at a UCD group, it will be automaticallydistributed to the first available group member.

After a predetermined time interval, calls in queue will receive recordedannouncements and/or music. Each UCD group can be assigned, viaMaintenance and Administration (M&A) commands, with a uniqueannouncement and music pattern.

One overflow destination is allowed per UCD group. Overflow will occur ifthere is an idle member in the assigned overflow group. When the overflowoccurs, the first call in queue will be removed from the queue and routedto the overflow group. If the assigned overflow group is busy, the call willstay in the original queue and will retry again. Any additional calls waitingin the same queue will not overflow until the first call has successfullyterminated to the assigned overflow group.

This feature allows a UCD group member to be temporarily unavailable forincoming calls. The member can activate this feature by pressing the UCDaccess key or by entering a feature access code.

UCD pilot numbers can be assigned as Direct Inward Dialing (DID) orListed Directory Numbers (LDN). If a DID/LDN/DISA call is routed to aUCD queue, the answer supervision signal can only be transmitted to thecentral office after the call has been answered by a UCD group member oran announcement machine.

System Features

The PERCEPTION 4000 system suppor ts the use of a UniformNumbering Plan in a networking environment. This is one of the variousnetworking options available to the system. Refer to the CoordinatedNumbering Plan and PERCEPTION 4000 Networking system features forfurther information.

The Uniform Numbering Plan routes inter-system station calls by means ofLeast Cost Routing (LCR). Different systems (switches) within the samenetwork do not have to share the same numbering plan for stationnumbers. Instead, numbers can be translated by the PERCEPTION 4000system in order to route calls to other networked switches. Digits can beadded or deleted to achieve appropriate dialing addresses.

Each switch in a UNP network environment is identified by a uniqueLocation Code, which is used to inform the system which routing patternsmay be used to route calls, and which digits need to be translated. Thisarrangement provides completely transparent dialing to the network user.The system does all of the necessary digit manipulation to access theproper switch and telephone device.

To make an inter-system station call via UNP, a caller enters a NetworkAccess Code (1 to 3 digits) and dials the desired network number. ThePERCEPTION 4000 system then checks its own Location Code by usingNetwork Digit Analysis and, if allowed, the call is sent to the distant end. Ifan invalid access code has been entered, the calling party will hearreorder tone. If all trunks are busy, the call will be camped-on to the TIEtrunk group or will be routed as assigned in the system database.

Forced Account Code entry is not required for UNP calls.

UNP calls are not checked by Outdialing Restrictions; however, if desired,UNP calls can be restricted through Facility Restriction Level (FRL) andFacility Restriction Level Profile (FRLP) assignments.

UNP Location Codes are recorded in the Station Message DetailRecording (SMDR) records.

The routing of UNP calls over the least expensive call facilities isdependent on the proper configuration of Least Cost Routing.

System Features

The Simplified Message Desk Interface (SMDI) provides the means ofinterfacing voice messaging system products with the PERCEPTION 4000system. PERCEPTION offers two SMDI protocols:

SMDI InterfaceSoftware option SFT-Rel 1.0 SMDI conforms to Bell CommunicationsResearch (Bellcore) specification TR-TSY-000283, Issue 1, July 1985.This option allows voice messaging equipment supporting the Bellcorespecification to operate with the PERCEPTION 4000.

The voice messaging equipment and the PERCEPTION 4000 system areinterconnected directly through a full-duplex RS-232C serial link. This linkis used to transmit control messages between the PBX and the voicemessaging equipment.

Data transmission over the serial link is performed Least Significant Bit(LSB) to Most Significant Bit (MSB). All characters are standard 7-bitASCII characters. The VMS port data transmission parameters are asfollows:� Baud Rate 1200 baud� Data Bits 7� Parity Even� Frame Start One start bit� Frame Stop One stop bit

PBX to voice messaging equipment messages supported by the VoiceMessaging/SMDI interface are as follows:� Directly Dialed Call to voice messaging equipment� All Calls Forwarded to voice messaging equipment� Busy Line Forwarded to voice messaging equipment� Line Not Answered Forwarded to voice messaging equipment

Voice messaging equipment to PBX messages supported by the VoiceMessaging/SMDI interface are:� Turn on Message Waiting Indicator for Line� Turn off Message Waiting Indicator for Line

For customers who prefer to utilize their present voice mail/voiceprocessing system, the PERCEPTION 4000 system supports the BellCommunications Research (Bellcore) Simplified Message Desk Interface(SMDI), Technical Reference TR-TSY-000283, Issue 1, July 1985. Voicemail systems which support this interface can be integrated with thePERCEPTION 4000 system to obtain enhanced message notification andretrieval features. Since SMDI is not an industry standard, each vendor'simplementation of the interface may vary. Toshiba has tested the SMDIimplementation of many voice mail systems. For information regarding theresults of these tests, or to determine the compatibility of a particular voicemail system, consult your Toshiba sales representative. SMDI is anoptional feature of the PERCEPTION 4000 system.

Station FeaturesPERCEPTION 4000 AUTOMATIC ANSWER

Automatic Answer allows a PERCEPTION digital telephone or electronictelephone station user to answer internal calls via their speakerphone,without pressing the prime line appearance key or manually activating thespeakerphone. Automatic Answer applies to calls that ring a station'sprime line and/or intercom line(s).

A telephone with a designated ACD agent line can also receive calls tothat line via Automatic Answer. In this case, calls can be either internal orexternal.

To activate Automatic Answer, the station user presses the AutomaticAnswer (AUTO) access key from any call state. Display telephones willmomentarily display the message “AUTO ANSWER.” After featureactivation, the station's microphone and speaker will be automaticallyactivated if either an internal call terminates at the station’s prime orintercom line, or an internal/external call terminates at the station's ACDagent line. The station user will hear a tone and can then either pick up thetelephone handset or continue the conversation through the speaker. Tocancel the feature, the user simply presses the AUTO key a second time.

When a station user places a call to a station registered with AutomaticAnswer, a tone will be sent to the called station, alerting the recipient andplacing the called station in speakerphone mode. At this point, thereceiving station (display telephone) will indicate the name and extensionnumber of the internal calling party. External calls to ACD agent lines willbe indicated through displayed trunk numbers.

The following types of calls to prime or intercom lines will not be subject toAutomatic Answer. These calls will directly ring the called station:� Terminating incoming trunk calls such as DID, DIT, and TIE calls� Recalls—Camp-on Callbacks, Call Park Recalls, or Call Hold Recalls� Transferred trunk calls

The following types of calls to ACD agent lines will not be subject toAutomatic Answer, and will directly ring the called station:� Recalls—Camp-on Callbacks, Call Park Recalls, or Call Hold Recalls

Automatic Answer can be activated while a telephone is in either an idle,ringing, or talk state. If the feature is activated while a call is in progress,Automatic Answer will apply to the next incoming internal prime line orintercom call, or the next internal/external ACD agent call.

Automatic Answer can be canceled while a telephone is in either an idle ortalk state. If the feature is canceled while a call is in progress, the next callto the station will ring as a normal call.

The ability of a station to automatically answer calls on prime and/orintercom lines is determined by separate station attribute assignments.

Station FeaturesPERCEPTION 4000

Call Forward allows calls placed to a station, including Direct InwardDialing (DID) and TIE calls, to be automatically redirected to apredetermined internal destination or off-premises location.

PERCEPTION 4000 supports three types of Call Forward, allowing calls tobe forwarded based on certain conditions. Calls can be forwarded oneither an All Calls, No Answer, or Busy/No Answer basis. In order for astation user to access any of these Call Forward types, the station must beallowed access through its assigned Class of Service (COS).

To register Call Forward—All Calls, No Answer, or Busy/No Answer on adigital or electronic telephone, the station user presses the desired CallForward access key (or enters the appropriate Call Forward access code).If the requested feature is available, the Call Forward key's LED will flashand display telephones will display "ENTER DESTINATION." The usermay then dial the desired destination directory number. If registration issuccessful, the LED will light solid. If the requested Call Forward feature isdenied at the station or if a destination number has been misdialed, theLED will flash red.

Once Call Forward is registered at a Toshiba electronic or digital displaytelephone, the LCD display screen will provide an indication of CallForward registration. Information shown on the first line of the display willinclude the Call Forward type (All Calls, No Answer, or Busy/No Answer)and the destination party's name and number. This information will remainon the display as long as the station is in the idle state. The ACDinformation display will override the Call Forward display when the agentlogs in.

To cancel Call Forward, the station user simply presses the activated CallForward access key (extinguishing the key's corresponding LED) or dialsthe Call Forward Cancellation access code. If the cancellation issuccessful, the user will hear success tone. It is not necessary to cancelone type of Call Forward before activating another type, since eachregistration overrides the last entry.

For multi-line stations, Call Forward will apply only to calls to the station'sprime directory number. Calls which terminate at any of the station's otherlines will remain available for answering.

When a PERCEPTION 4000 proprietary 20-key digital telephone(HDT2020SD) user places a call to a station that has Call Forwardregistered, the calling station will display the name and number of thecalled station, together with the message “FORWARDED” or "NOANSWER." The telephone will also indicate the name and number of thestation to which the call is forwarded.

To access Call Forward—All Calls, No Answer, or Busy/No Answer from astandard telephone, the station user takes the telephone off-hook, listensfor dial tone, enters the appropriate Call Forward access code, dials the

desired destination directory number, and then hangs up. If feature accessis unsuccessful due to misdialing or Class of Service restrictions, the userwill hear reorder tone. Reorder tone will also be heard if an invaliddestination is detected by the system.

To forward calls to an off-premises location, the station user uses thesame procedures used for internal forwarding and forwarding cancellation.Call Forward to the off-premises location will be denied if the forwardingstation is restricted from calling the specified destination.

Calls can be forwarded twice. If a station has Call Forward—All Callsregistered, and a call has already been forwarded twice before reachingthat telephone, that telephone will ring.

There is no limit to the number of stations that can forward calls to a singlestation. If two stations forward to each other, they will each receive theirown calls.

A station that has been registered as a Call Forward destination can call,camp-on, or perform a camp-on transfer to the forwarding station.

If a station with Call Forward registered is dialed directly, then the systemwill attempt to forward a call regardless of a pre-assigned station huntingarrangement. The system will also attempt to forward a call beforeallowing a camp-on to a busy destination.

Recalls and camp-on callbacks will not be forwarded. If a camp-on isinitiated from a station with Call Forward registered, a camp-on callbackwill recall to that station.

Intercom calls are not forwarded along with regular station calls. Incomingintercom calls to a station that has its prime line forwarded, will stillterminate and ring at the station.

An unanswered station that is registered with Call Forward—No Answer orCall Forward—Busy/No Answer will still receive voice calls. Voice calls willnot be forwarded. If a calling party returns a voice call to ringing, then thecall will be routed to the Call Forward destination after the preprogrammedNo Answer time-out period elapses.

A station’s outgoing call capabilities are not affected by the activation ofthe Call Forward feature.

When a station user calls a station that is forwarded, the user has theoption of using either Callback Messaging or Predefined Text Messaging.When used, a message will be registered at the called station, not theforwarded-to destination.

Station FeaturesCALL HOLD PERCEPTION 4000

Call Hold allows a station to place a call in a hold state and then hang upor initiate a call on another line. This feature differs from the ConsultationHold ("soft hold") state in that the originating station cannot initiate anyother feature or call on the same line being used for the held call.

PERCEPTION digital and electronic telephone users can initiate either a"hard hold" or an "exclusive hold" by using the fixed HOLD key on thetelephones. Hard Hold allows a held call to be retrieved by any stationcontaining an appearance of the line on which the call is held. ExclusiveHold restricts call retrieval to the station initiating the hold.

Standard telephone users can initiate a "hard hold" by using the telephonehookswitch or Tap key and entering a Call Hold access code.

Parties who are placed on hold will hear either Music-on-Hold or quiettone, depending on PERCEPTION 4000 system configuration.

To place a call on "hard hold" from a PERCEPTION digital or electronictelephone, the station user simply presses the HOLD key. The LEDcorresponding to the line on which the call is held will flash to indicate theheld call. Other telephones with that same line appearance will alsoindicate the held call through a flashing LED. To retrieve the call from anyof these line appearances, the station user simply presses the flashing linekey.

To place a call on "exclusive hold," the user presses the HOLD key twice.In this case, the station initiating the hold will indicate the held call througha flashing LED, while other line appearances will indicate that the line is inuse, through a solid LED. The initiating station can retrieve the held call bypressing the flashing line key. The call will not be retrievable from anyother line appearance.

After a call has been placed on either hard or exclusive hold at aPERCEPTION digital or electronic telephone, the initiating party can hangup his/her telephone. Calls placed on hold will recall the station whichinitiated the hold, after a predetermined time period has elapsed. Therecall can be answered only at the station which initiated the hold.

To place a call on "hard hold" from a standard telephone, the station userpresses the telephone hookswitch or Tap key, and enters the Call Holdaccess code. The user can then either hang up or remain off-hook. Toretrieve the held call, the station user simply presses the hookswitch orTap key. If the user hangs up after initiating Call Hold, the held party willrecall after a predetermined time period. The user can answer the recall bysimply taking the telephone off-hook.

If a held party hangs up before the call is retrieved, the party attempting toretrieve the call will hear dial tone.

Station FeaturesPERCEPTION 4000PERCEPTION 4000 CAMP-ON

The Camp-on feature allows a caller who encounters a busy station ortrunk group to wait, either on- or off-hook, for the party or trunk group tobecome available. When using an off-hook camp-on, the caller simplywaits off-hook for the called party or trunk group to become idle. Whenusing an on-hook camp-on, the caller can hang up and will receive acamp-on callback once the called party or trunk group is available. Astation user can camp-on to a trunk group that has been accessedthrough Least Cost Routing, in order to maintain economical call routingduring busy calling periods.

An off-hook camp-on has priority in the system over an on-hook camp-on.

Camp-on queue size is programmable via an M&A command.

After reaching a busy station or trunk group (a station cannot camp-on to aringing line), a station user can camp-on to the busy station/trunk group bywaiting off-hook for busy tone to change to success tone. Multi-linetelephone users can also perform a camp-on by using a preprogrammedfeature access key. PERCEPTION 4000 proprietary 20-key digitaltelephone (HDT2020SD) users have the additional option of pressing theCAMP soft key to initiate a camp-on. When this soft key is pressed,success tone will sound to indicate that camp-on has been activated. Atthis point, the user can either remain off-hook, or can hang up and wait fora camp-on callback.

With an on-hook station camp-on, a callback will occur when both thecalling and called stations are idle. The system will ring the calling stationfirst, and once the station user answers, the system will ring the calledstation. If the station that initiated the camp-on does not answer a camp-on callback within a predefined period of time, ringing will stop and thecamp-on will be canceled.

With an on-hook trunk group camp-on, a callback will occur when both theinitiating station and a trunk within the trunk group are idle. In thissituation, the system will seize the available trunk and will ring the initiatingstation. When the call is answered, the answering party will hear PBX dialtone and will hear the previously-dialed digits being outpulsed. If thestation is not answered within a predefined period of time, the ringing willstop and the system will make two more callback attempts.

To cancel an on-hook camp-on, station users can either press a Camp-onCancellation access key or enter a Camp-on Cancellation access code.

While waiting for a camp-on callback, a station user can make additionalcalls. The callback will not occur until the station’s prime line is idle. Allcallbacks will r ing the station’s prime line, regardless of the lineappearance that was used to initiate the camp-on.

When a station user has initiated an off-hook camp-on and then placedanother call, the user can drop this second call without hanging up bypressing the Release (RLS) key. This will prevent a camp-on callback fromringing the initiating station, and will allow the station user to place anothercall.

DESCRIPTION

OPERATION

2-17Addendum -December 1993


A camp-on callback can only be answered at the station from which it wasinitiated. A callback cannot be accessed via Call Pickup or from asecondary line appearance.

A camp-on callback will not be forwarded. If a station that has initiated acamp-on has Call Forward registered, the callback will still ring the station.

A camp-on callback will override Do Not Disturb. If a station that hasinitiated a camp-on has Do Not Disturb registered, the callback will stillring the station.

When calling a station that has Do Not Disturb activated, the caller willhear busy tone. In this situation, camp-on will not be allowed. Busy tonewill not change to success tone and the CAMP soft key option will notappear on PERCEPTION 4000 proprietary 20-key digital telephone(HDT2020SD) displays.

A station cannot camp-on to an Automatic Call Distribution (ACD) orUniform Call Distribution (UCD) pilot number. However, a station cancamp-on to an individual UCD member.

Only off-hook camp-ons can be performed from a private line. Stationusers cannot camp calls onto a private line. An attendant, however, canuse Camp-on Transfer to camp an incoming call onto a private line.

The PERCEPTION 4000 system will perform any registered Call Forwardor assigned Station Hunting before attempting camp-on.

Calls placed from a hotline, or via Autodial, Last Number Redial, or SpeedCalling can be camped-on to a busy station or trunk group in the samemanner as other call types.

Each station can initiate only one camp-on (either station or trunk) at atime. If an incomplete camp-on is not manually canceled, it will beautomatically canceled by the system after a predetermined time period.

When transferring a call to a busy station, a station user can use Camp-onTransfer to camp the call onto the busy destination.

Message Waiting Indications inform a station user that another party hasregistered a message at the station or in the station's associated voicemailbox. The PERCEPTION 4000 system provides two Message WaitingIndication options for standard, analog single-line (500/2500) telephones.If a 500/2500 telephone has a built-in message waiting indicator lamp, thePERCEPTION 4000 system will light this lamp when a message isregistered. If the telephone is not equipped with an indicator lamp, thesystem can provide "stutter dial tone" when a message has beenregistered and the station user goes off-hook. A telephone equipped witha message waiting indicator lamp will receive both types of indication. Inorder for an analog station to receive a Message Waiting indication, thestation must be assigned in the system database as a message waitingtelephone (i.e., the telephone must be assigned as "ANMW").

A station user can register a message at a 500/2500 telephone throughthe use of either a designated feature access key or access code. Oncethe message is registered, the station will be informed of the waitingmessage through one or both of the two types of message waitingindications. Depending on the system configuration, an indication mayalso be given whenever a message has been left in the station'sassociated voice mailbox. The two types of message waiting indicationsare described below:

� For 500/2500 Sets with Message Waiting Indicator Lamp:When a message is registered a a 500/2500 telephone (or when amessage has been left in the station's associated voice mailbox), thestation's message waiting indicator lamp will light. To respond to themessage indication, the user takes the telephone off-hook and dialsthe Message Waiting Return access code.

� For 500/2500 Sets without Message Waiting Indicator Lamp:When a message is registered a a 500/2500 telephone (or when amessage has been left in the station's associated voice mailbox), thestation user will hear stutter dial tone when taking the telephoneoff–hook. To respond to the message indication, the user dials theMessage Waiting Return access code.

After a station user enters the Message Waiting Return access code, thePERCEPTION 4000 system will automatically route the user to either theassociated voice mail system or to the station which registered themessage, depending on the nature of the message. If the messageresides in the station's associated voice mailbox, the system will route theuser to the voice mail system. Once the system is accessed, the user canlisten to, cancel, or save messages by following the voice mail systemoperating procedures. If the message has been left by a station, thePERCEPTION 4000 system will instead attempt to call back theregistering station. If a 500/2500 telephone receives both voice mailmessages and a message from another station (Callback Message), thePERCEPTION 4000 system will always attempt to call the voice mailsystem first. If, after retrieving voice mail messages, either the station's

Message Waiting indicator lamp is still lit, or stutter dial tone is still heard,it indicates that a callback message has also been registered at thestation. To respond to this message the user enters the Message WaitingReturn access code a second time. The system will then route the user tothe station which registered the message.

A 500/2500 telephone can receive one voice mail message indication andone Callback Message indication. A voice mail message indication canrepresent any number of registered voice mail messages.

Message Waiting indications will be retained until the voice mail system orregistering station (or both) is/are called back. As an alternative toanswering messages, a user can cancel a message waiting indication byentering the Message Waiting Cancellation access code. The entrance ofthis code will clear any callback message as well as an indication that isassociated with voice mail messages. Actual voice mail messages will notbe canceled. These messages must be canceled via voice mail systemoperational procedures.

A 500/2500 telephone must be equipped with an indicator lamp in order toreceive a visual message waiting indication. Additionally, each of thePERCEPTION 4000 system's Modular Line/Trunk Units (MLTUs) thatsupports 500/2500 telephones with indicator lamps MAY need to beequipped with a MWPU card. This card supplies additional power which isused to light message waiting indicator lamps. Consult your authorizedToshiba dealer to determine if your system requires this additionalhardware.

No special hardware is required for the audible stutter dial tone indication.

The prime line and logical lines on a Toshiba electronic or digital multi-linetelephone allow the telephone user to place and/or receive more than onecall at a time; however, the lines are essentially unrelated for other callprocessing operations. If a call is placed to the prime line of a multi-buttontelephone and the line is busy, the call will receive busy treatment even ifthere are idle logical lines available on the telephone.

The Multi-line Hunting feature allows a relationship to be establishedbetween the telephone's prime line and up to seven logical lines, bydefining the lines as a "rotary group" in the system database. This rotarygrouping provides the capability to hunt for an idle line within the rotarygroup, to forward all lines within the group at the same time, and toregister Do Not Disturb for all lines within the group.

Member lines of a rotary group must all appear on the same telephone.ACD lines, intercom lines, hotlines, private lines, and secondaryappearances may not be members of a rotary group.

MULTI-LINE HUNTINGWhen a call is placed to any rotary group member line and the desired lineis busy, the system will search the rotary group for an idle line. If an idleline is found, the call will ring and may be answered by the called party. Ifall rotary group lines are busy, the call will receive the busy-phoneappropriate treatment.

FORWARDINGWhen Call Forward (Call Forward/All Calls, Call Forward/Busy, or CallForward/No Answer) is activated for the telephone's prime line, all logicallines in the rotary group receive Call Forward treatment as follows:

� Call Forward/All Calls— A call to any of the rotary group's memberlines will be forwarded to the registered destination without ringing thetelephone.

� Call Forward/Busy — Call Forward/Busy will have no effect unless allrotary group member lines are busy. If all rotary group lines are busy,the call will be immediately forwarded to the registered destination.

� Call Forward/No Answer — A call to a busy line in the rotary groupwill cause the system to search the group for an idle line. When an idleline is found, the call will ring that line. If the call is not answered withinthe no-answer timeout period, the call will be forwarded to theregistered destination.

DO NOT DISTURBWhen Do Not Disturb is activated for the telephone's prime line, Do NotDisturb will also apply to all logical lines in the rotary group.

UNIVERSAL CALL DISTRIBUTIONA rotary group member line may be a member of a UCD group.

CAMP-ONWhen all member lines of a rotary group are busy, a caller can establishcampon (either offhook or onhook) to the entire rotary group. When amember line becomes idle, the the system will ring the line and provideringback tone (for an off-hook camp-on) or callback (for an on-hook camp-on) to the initiating station.

If a station with a rotary group initiates an on-hook camp-on, and the lineis busy when callback is sent, the system will search the rotary group foran idle line to complete the callback.

CALL WAITINGWhen a call camps on to a busy rotary group, the active line will receive acall waiting indication.

CALL MESSAGINGWhen calling another station whose prime line is assigned to a rotarygroup, a station user can leave a message. If the call hunts to one of therotary lines, the message will still be recorded on the station's prime line.

SECONDARY APPEARANCESA rotary group member line may have secondary appearances on othertelephones.

SMDRWhen a call is recorded for any member of a rotary group, the prime line'sDN will be recorded.

A PERCEPTION 4000 HDT2010S/HDT2020SD digital telephone user canadjust the pitch and volume of the telephone's ringer. Pitch adjustmentenables a user to alter the ringer's pitch so that it can be identified fromother telephones ringing within a certain area. Volume adjustment enablesa user to alter the ringer's volume level to fit specific call environments.

Both pitch and volume adjustments can be made when a telephone is idle.To alter the ringer's pitch, the user first enters the Program Mode bypressing the designated Program Mode access key. At this point, the usercan then press one of the digits 1 ~ 4 on the telephone dialpad in order tospecify the desired pitch level. When one of these dialpad keys is pressed,the telephone will ring at the key's corresponding pitch level for as long asthe key is pressed. This provides the user with an audible indication of theselected pitch level. The user can press any of the digits 1 ~ 4 as manytimes as desired, however, the last selected pitch will remain in memory.After exiting Program Mode, any new incoming calls will ring at theselected pitch level.

To alter the volume of the telephone's ringer, the user presses the VolumeUp/Down Control keys that are located to the left of the dialpad. Wheneither of these keys is pressed, the telephone will ring at an increasing ordecreasing level. Once the desired volume level is reached, the user stopspressing the keys. Any new incoming calls will ring at the selected volumelevel.

In the event of a system redundancy switchover or a local power loss (e.g.,the telephone is unplugged), the telephone's ringer pitch and volumelevels will reset to their default levels.

The adjustment of a PERCEPTION 4000 digital telephone's ringer pitchand volume levels can only be made when the telephone is idle. Whileinvolved in a call, Program Mode cannot be activated. Also, during this callstate, Volume Up/Down Control keys are used to control the handsetvolume level.

The Trunk Verification from Station feature is basically a Maintenance andAdministration-type feature which allows individual outgoing CO trunkcircuits to be verified from a station. This is useful for troubleshootingpurposes. Stations can be any system-compatible telephone: aPERCEPTION 4000 digital telephone; a Toshiba electronic or DKT digitaltelephone; or a standard 500/2500 telephone.

To verify a trunk, the station user enters the Trunk Verification accesscode, and then enters the trunk equipment number. Depending on thestatus of the trunk, the user will receive busy tone (if the trunk is busy) ordial tone (if the trunk is idle). Once dial tone is heard, the user may placecalls over the CO trunk. Stations that are equipped with an LCD displaywill display will provide an indication of trunk status.

The Trunk Verification from Station feature does not allow the user tobreak into or override a busy trunk; the user may only verify the status ofthe trunk.

Access to the Trunk Verification from Station feature is subject to Class ofService (COS) restrictions.

Trunk Verification from Station is not applicable to DID or PRI trunks.

During trunk verification, the trunk being verified cannot be placed on anytype of hold (Consultation hold, hard hold, exclusive hold, etc.).

An attendant cannot interrupt Trunk Verification from Station featureoperation by breaking into either the station performing the operation orthe trunk being verified.

The Emergency Calls feature allows emergency incoming calls to behighly visible at the attendant console so that they can receive high prioritytreatment.

There are four levels of Emergency Calls. Call types assigned to the firsttwo levels are given the highest incoming call priority. Call types that areassigned to emergency levels 3 and 4 can be assigned a particular priorityin the system database.

Once originated, an emergency call will ring all selected attendants thatare not in the Position Busy mode. If the attendants are idle, theemergency call will be assigned using normal call assignment rules. If theattendants are busy, one of the consoles will be selected automatically bythe system, lighting an Incoming Call Identification (ICI) key on the consoleand alerting the attendant that an emergency call has arrived.

Consoles can be assigned to receive maximum level ringing indications forincoming emergency calls. In this case, a console's preset ringing volumelevel is ignored, and an emergency call will ring at maximum level for theduration of the call.

Emergency calls will display a distinctive emergency message which isdefinable at the system level by the system administrator. (EachEmergency Call level may be assigned with a unique destination andmessage.) The source directory number, location of the calling station,name of the station user, and emergency type will also be listed on theelectroluminescent (EL) display.

Emergency calls do not appear at only specific attendant groups, but aredirected to all consoles in the system.

This eliminates the need for the data user tospecify a modem or modem pool when dialing. This feature applies to alldata calls.

Data destination numbers are assigned to modem pools through databaseprogramming. Numbers are listed in the High-usage Data Destinationtable. Once programmed, a data user can utilize Automatic Modem PoolSelection by simply accessing a data line and dialing the desired datadestination number. Once dialed, the system will check the database tableand select a modem from the assigned modem pool. The call will thenproceed as a regular data call.

If a dialed data destination number is not assigned to a specific modempool, then the system will search for an available modem in the defaultmodem pool that is assigned to the dialing station.

If a data user specifies a specific modem prior to dialing a data destinationnumber that is assigned to a modem pool, the manual selection willoverride Automatic Modem Pool Selection.

Data destination numbers can be assigned to Autodial keys. A data linecan be specified when programming these keys. If a dialed number isassigned to a modem pool, then the system will automatically select amodem from this group.

To override Automatic Modem Pool Selection, a modem can be specifiedin an Autodial sequence.

If a data destination number that is assigned to a modem pool is dialed,the dialing station will retain that number for later access through DataLast Number Redial. When using this feature, the system wil lautomatically access the modem pool that is assigned to the redialednumber.

When using Data Speed Calling, Automatic Modem Pool Selection willapply if the dialed data number is assigned to a specific modem pool. Ifthe number is not assigned to a modem pool, then a modem within thedialing station's default modem pool will be accessed.

Data Authorization allows a station user to temporarily change a station'scalling privileges. By entering a specific data authorization code, thestation user can temporarily alter the station's Class of Service (COS),Destination Restriction Level (DRL), Facility Restriction Level Profile(FRLP), and Queuing Priority Level (QPL).

Only one author ization code may be entered dur ing a call. Allauthorization codes in a system must be of the same length.

The system administrator must set up an Authorization Code Table (ACT)which contains a COS, DRL, FRLP, and QPL definition for each validauthorization code.

An authorization code is entered via different methods, depending on thetype of device used. To enter an authorization code via keyboard dialingand the User Command Interface (UCI), the user simply has to enter“AUTH” via the terminal keyboard and will then be prompted for therequired entries. To enter an authorization code via a PERCEPTION 10-key (HDT2010S) or 20-key (HDT2020SD) digital telephone, the userpresses the Data Line key, presses the Authorization Code (AUTH) accesskey (or enters the Authorization Code access code), enters theauthorization code itself, and then dials the desired destination number.

The actual authorization code that is entered for a call will not be displayedon the Liquid Crystal Display (LCD) of display telephones. Thesetelephones will only display messages indicating Data Authorizationfeature activation. Any authorized change in a station's calling capabilitiesexists only for the duration of the data call, with previous attributesrestored after the call is terminated. The entered authorization code isvalid for one call only; it must be re-entered for each subsequent call.

DATA INTERFACE UNIT PERCEPTION 4000

A data interface unit (DIU) provides the access point of attachmentbetween data communication devices, such as data terminals or hostcomputers, and the PERCEPTION 4000 system. The system iscompatible with both the Integrated Data Interface Unit (DIU-I) and theStand-alone Data Interface Unit (DIU-S). Both models are supported bythe DSTI digital line card.

The DIU-I resides inside of a PERCEPTION 10-key (HDT2010S) or 20-key(HDT2020SD) digital telephone. This allows data calls to utilize thetelephone's LEDs, Liquid Crystal Display (LCD), ringer, dialpad, andfeature keys. Voice and data calls can be performed simultaneously viaone pair of wires, using the "2B + D" transmission format (two 64 KBPS B-channels and one 16 KBPS D-channel).

The DIU-S is designed for users who need data service only. It can beconnected to a personal computer, printer, modem, or host computer, andcan also be used in constructing modem pools.

In addition to the above distinctive characteristics, the two different DIUmodels share the following common attributes:� Asynchronous operation� Data Communications Equipment (DCE)/Data Terminal Equipment

(DTE) interface� EIA RS-232-C interface� Half- and full-duplex operation

� DIU Indicators—The status of the DIU-S is indicated by the LED and abuzzer.

� Test Key and Test Mode Definition—The manual TEST key is used toactivate/deactivate local testing of the DIU-S, which assists introubleshooting problems with the data communication interfacebetween the DIU and the attached device.

� Control Signaling—DIU-Is use the 2B+D format over a single twistedpair; both voice and data control signaling share the common D-channel. DIU-Ss use the 1B+D format; only the data control utilizesthe D-channel.

� Data Transport Protocol—Data transport between DIUs takes placeover the B-channel.

� RS-232-C Interface—The DIU card provides an RS-232-C femaleconnector, enabling DCE operation. However, under properconfigurations and crossed RS-232-C cables, the DIU may emulatethe DTE operation required for modem pooling.

� DIU Operation Modes—DIUs interface to data devices in twooperating modes: the COMMAND mode which supports the UserCommand Interface (UCI), and the DATA TRANSFER mode.

� DIU Operating Parameters—DIU parameters are set up viaMaintenance and Administration (M&A) commands. All selections arechecked by software control to ensure consistency with otherparameters. The parameters involved are:�� Asynchronous Mode�� Half-/Full-duplex operation�� DCE/DTE Emulation

External data calls can share the same trunks as voice calls so that LeastCost Routing (LCR) applies. This can significantly reduce calling costs insystems that have moderate-to-heavy outgoing data traffic.

LCR for data calls shares the same access codes and numbering systemas those used for voice calls, with the following exceptions:� Data Call by Name—Names can be translated into a string of digits,

including the LCR access code.� Modem Selection—The particular type of modem can be selected for

an outgoing data call.� Class of Service (COS) and Restriction—Specific COS assignments

and restriction must be assigned to data stations. For integrated voiceand data users, the data COS assignments and restriction can bedifferent than those for voice.

DATA LEAST COST ROUTING PERCEPTION 4000

DESCRIPTION


PERCEPTION 4000 uses the Distributed Data Port Hunting method tosearch for an idle data port within a Data Port Hunting group. A Data PortHunting group is a pool of data ports with similar functions and compatiblecharacteristics. The system administrator is responsible for defining theData Port Hunting groups, the order of members in each group, and thepilot number of each group.

To access this feature, the station user simply dials the desired Data PortHunting group's pilot number. Since each data port within a Data PortHunting group has its own directory number (DN), a station user canaccess a data port by dialing either the data port’s specific DN or itshunting group pilot number. Note that hunting will not occur if the dialeddata port is not a member of a Data Port Hunting group. Pilot numbers ofData Port Hunting groups can be programmed into the Data Speed Callinglist.

Distributed Hunting starts as soon as the pilot number is dialed. Huntingstarts from the data port which immediately follows the port that was lastconnected to a call. The system continues to search down the list until anidle data port is found.

Data calls to Data Port Hunting group members can be made via the UserCommand Interface (UCI). When using UCI, users can access datastations and Data Port Hunting group pilot numbers by using the Data CallBy Name feature. If the Data Call By Name feature is used to access pilotnumbers, the system administrator must also assign specific names totheir associated pilot numbers.

If a PERCEPTION 20-key digital telephone (HDT2020SD) places a datacall to a Data Port Hunting group, the telephone will display the directorynumber of the hunted data port.

Data Speed Calling allows data users to call selected numbers by meansof an abbreviated dialing sequence. Data connections can be establishedvia Speed Calling from a computer or terminal keyboard or from aPERCEPTION 10-key (HDT2010S) or 20-key (HDT2020SD) digitaltelephone.

Access codes for internal stations, trunk groups, Least Cost Routing(LCR), and external modems can be included in the Speed Callingnumber.

Data Speed Calling can be either system-wide (System Speed Calling) orassigned on a group basis (Group Speed Calling). The System SpeedCalling list is shared by all PERCEPTION 4000 voice and data stations,whereas a Group Speed Calling list is shared by only a group of specifiedvoice and data stations.

System Data Speed Calling is programmed through Maintenance andAdministration (M&A) commands. The list is shared by all voice and datastations. To access System Data Speed Calling, the data user presses theData Line key on the PERCEPTION digital telephone, presses the SpeedCalling (SYSD) access key (or enters the Speed Calling access code),and then enters the Speed Calling index number. The Speed Calling indexnumber refers to the location of a specific number sequence in the Systemor Group Speed Calling number listing. Speed Calling can also beaccessed via the User Command Interface (UCI). (Refer to thePERCEPTION 4000 Data Interface User Guide for detailed information.)

Group Data Speed Calling numbers are also programmed by the systemadministrator via the M&A console. Group Data Speed Calling is activatedin the same manner as System Data Speed Calling; however, the calleddestination number must be assigned to a Group Speed Calling numberlisting which the station user can access. A user can access only thosenumber listings assigned to his/her Speed Calling group(s).

The Data Speed Calling feature can be used as part of the data call setupprocedure.

Speed Calling numbers are checked whenever appropriate in the routingprocess, according to the calling data station’s Class of Service (COS),Destination Restriction Level (DRL), Facility Restriction Level (FRL),and/or Queuing Priority Level (QPL).

Modem Pooling allows data stations to share modems for sending andreceiving data over trunks. This eliminates the need for each user or trunkto have its own separate modem. The PERCEPTION 4000 system alsosupports Automatic Modem Pool Selection which allows commonly-useddata numbers to be assigned to a specific modem pool, so that a modemwill automatically be selected whenever those numbers are dialed. (Referto the Automatic Modem Pool Selection data feature for additionalinformation.)

Modem pools must be configured by the system administrator viaMaintenance and Administration (M&A) commands. Members of eachmodem pool must share the same communication characteristics such asdata speed, transmission mode, data call direction mode, etc.

Modem pools can be accessed by PERCEPTION 10-key (HDT2010S) and20-key (HDT2020SD) digital telephones, and by keyboard dialing via theUser Command Interface (UCI). A modem pool can also be accessed froma modem located outside the system. In this case, the remotely-locatedmodem pool will be automatically connected to the designated datatermination point through Inward Routing. A modem from the datatermination point's default modem pool will be selected.

Outgoing modem calls can be initiated via Manual Dialing, Autodial, Callby Name, Last Number Redial, or Speed Calling. If only the Direct TrunkGroup Access/Least Cost Routing access code and destination number isentered, when placing a data call from a data station, then the High-usageData Destination table in the system database will be searched. If a matchis found, the modem pool indicated in the table for the dialed number willautomatically be used for the call. If a match is not found, the defaultmodem pool assigned to the data station in the system database will beused.

A modem pool can also be specified during dialing. To select a modempool other than the default, the data user simply presses the Data Linekey, enters the Modem Pooling access code and the number of thedesired modem pool, and then dials the desired destination number.

Modem call clearing can be initiated by the data station user by pressingthe Data Line key or the BREAK key, by entering a "Disconnect" commandto UCI, or by powering down the data terminal. A modem call is alsocleared whenever the connected distant modem is placed on-hook. Whenthis occurs, Data Carrier tone is no longer received by the other end, andthe call will be disconnected.

In addition to placing data calls directly from a PERCEPTION 10-key(HDT2010S) or 20-key (HDT2020SD) digital telephone with an IntegratedData Interface Unit (DIU-I), data users can perform data call operationsfrom a computer or terminal keyboard via the User Command Interface(UCI). UCI is Toshiba's user-friendly proprietary data command language,which provides step-by-step call processing display information on acomputer or terminal CRT (Cathode Ray Tube) screen.

Any ASCII computer or terminal with a CRT screen may be used for UCIoperation. Any PERCEPTION digital telephone with a DIU-I, or any Stand-alone Data Interface Unit (DIU-S) can be connected to the CRT screenunit so that UCI can be accessed.

The first step necessary to access UCI is to define the voice and dataports in system software. This is accomplished through Maintenance andAdministration (M&A) commands. Data details must also be assigned bothin the PERCEPTION 4000 system database and on the connected ASCIIterminal, so that aspects such as automatic speed, parity, stop-bit, anddata-bit detection abilities coincide. With this completed, the CRT can beconnected to a PERCEPTION digital telephone with a DIU-I, or to a DIU-S, via an RS-232-C cable.

Once all software coordination and cabling is performed, UCI can beaccessed by pressing the carriage return key on the connected ASCIIterminal keyboard. This will automatically signal the PERCEPTION 4000system of all details pertaining to data calls made from that terminal(automatic speed, data-bits, etc.), and will bring up the UCI prompt so thatdata calls can be made.

Once UCI is accessed, data users can enter alphanumeric commandsequences via the keyboard of the ASCII terminal, and can monitor theprogression of data calls (or activation of data features) from displaymessages on the CRT screen. As information is entered and processed,the screen denotes the called destination's number and name, the statusof the called destination, and various help messages. Each user commandconsists of a command code, which may or may not be followed by anyrequired parameter fields.
