1.1 Introduction

The 7302 ISAM is a frame based Digital Subscriber Line Access Multiplexer (DSLAM), that is, a Digital Subscriber Line (DSL) access multiplexer which is based on a frame forwarding architecture in a packet aggregation network.

General Network Topology

Figure 1-1 shows the basic network topology:

Figure 1-1 General network topology

User Side

At the user side, each 7302 ISAM terminates DSL links and a limited number of FE or GE links.

It is possible to connect subtending DSLAMs to the FE/GE links at the user side in:

• cascading mode: a chain of 1 subtending ISAM per ISAM• star mode: multiple subtending ISAMs per ISAM• ring mode (except when there is a ring behind a Hub-ISAM).

Figure 1-2 shows the cascading topology.

Network Side

At the network side, the 7302 ISAM terminates GE or FE links. The following configurations are possible:

• Connected to one or more Ethernet SwitchesThe Ethernet links can be connected to one or more Ethernet Switches. These Ethernet Switches forward the frames over the Ethernet based aggregation access network until they reach the IP Edge Router or BRAS of the corresponding Network Service Provider (NSP). At the IP Edge Router or BRAS, the frames enter the IP backbone of the NSP.

• More than one FE/GE link (link aggregation)In case of more than one FE or GE, Ethernet link aggregation is used.

• Directly connected to an IP Edge RouterThe 7302 ISAM can be connected directly to the IP Edge Router or BRAS. The Ethernet aggregation network is reduced to one or more parallel Ethernet links.

Note: A link is a term which is used to refer to the physical layer of an interface of the 7302 ISAM, for example, an ADSL link, an Ethernet link.



1.2 System Architecture

GeneralThe figure below shows the general functional architectures of the 7302 ISAM.

Figure 1-3 7302 ISAM Functional Architecture

The system consists of a Gigabit Ethernet switch fabric, that bridges or routes user, subscriber control and network management traffic between:

• on the subscriber side:a set of subscriber line interfaces and a number of sub-tending interfaces towards other, hierarchically subordinate DSLAM systems.

• on the network side:one or more Network Termination (NT) interfaces.

7302 ISAM SubsystemsThe 7302 ISAM is composed of the:

• ISAM Access termination Control and Management (IACM) subsystem This subsystem:

• contains the control functions of the 7302 ISAM on the NT board.• provides management interfaces on the NT board to the outside worlds and control

interfaces towards other boards (LT boards, NT I/O board).• contains the LT boards.• contains the NT I/O board.

SHub Subsystem

The Service Hub (SHub) subsystem multiplexes the Ethernet frames into a reduced set of network links (that is, aggregates traffic from / to subscriber interfaces on one or a limited number of network uplinks).

The SHub subsystem is integrated in a NT board. Figure 1-4 shows the connections of the LT shelf with the SHub subsystem. The SHub subsystem provides 24 FE/GE ports:

• 16 ports are used for connecting to each LT board• one port used for internal purposes (ECNT-A only)

• seven external ethernet ports with an optical, electrical FE or GE interface, which can be used for network uplinks, subtending links (aggregation of traffic from or to other DSLAMs) or Ethernet subscriber links.These seven ports are physically available:

• three on the Network Termination (NT) board itself• four on the NT I/O board.

1.4 ISAM with integrated Voice-band services

The ISAM with integrated Voice-band services (ISAM-V) provides support of POTS and ISDN services and connection to Next Generation Voice Networks (NGVN) via Voice over IP (VoIP).

Network ArchitectureFigure 1-5 shows the position of the ISAM-V in the NGVN.

Figure 1-5 Network Architecture

• The ISAM-V acts as an Access Media Gateway (MG) and connects the legacy NarrowBand (NB) user interfaces (Plain Old Telephone Services (POTS) and Integrated Services Digital Network (ISDN)) to the NGVN.

• The ISAM-V supports:• mixed configurations, where the NB user interfaces and MG Interface are integrated

in the same node• centralized configurations, where the MG Interface is located in a hub node and the

NB user interfaces in remote nodes.• The trunk MG links the NGVN with a Legacy network.• The softswitch is responsible for call control and charging, and communicates

with the MGs:• via the Media Gateway Control (MEGACO) protocol (ETSI RFC 3525 / ITU-T

H.248) for POTS• via the SIGTRAN Control protocol for ISDN

Note — H.248.16 (XDD Buffering) is also supported

Basically, XDD buffering is used in order not to lose digits when after matching with a valid dialplan the user still continues dialling. When XDD buffering is active, detected digits are kept in IVPS in a buffer as a digit string up to a timer expiration or when a new matching with the current valid dialplan happens.

APC

APC is the Voice Service Manager for Alcatel Access Nodes. It provides a full abstraction of the underlying technology used to provide the service with the following main features:

• Voice subscriber provisioning and line testing for individual subscribers or a set of subscribers that allows fast deployment of the network

• Open interfaces to OSS that eases massive deployment of the service, preventive and customer-on-call line testing and subscriber information alignment with OSS.

5530 NA

The 5530 NA is in charge of the PSTN line Testing functionality, which includes electrical measurements in the voice band to test the loop, testing of the POTS line termination, and testing of the POTS terminal equipment.

Management Interface

The management interface between the VEM and the IVPS offers a SNMP v1 protocol. There is also a direct interface (SNMPv1) between the APC and the IVPS.

The IVPS board is not equipped with a CT interface.



Product ArchitectureThe ISAM Voice Package architecture is that of the ISAM with the addition of voice services, which translates into the addition of three boards:

• one server board: IVPS, which is the VoIP gateway for ISAM-VNote: the IVPS is plugged in an LT position, but performs server functions.

• two LIM boards:• POLT board, providing POTS interface connectivity• BALT board, providing ISDN Basic Access (ISDN BA) interface connectivity

Architecture View

The following applies for the ISAM-V product architecture:

• ISAM-V nodes are connected to an EMAN• An ISAM-V node integrates either:

• the server card, IVPS, performing the signaling and OAM functions of the GW• a number of NB LTs cards (POLT-A and BALT-A) performing the media functions• both types together

• MEGACO and SIGTRAN signaling and external voice service OAM are terminated at IVPS

• Internal control and signaling communication between IVPS and NB LTs uses XLES protocol.

• IVPS card is located into a hub node• From the voice service point of view, one IVPS can control several ISAM-V

cascading nodes (up to 4 levels) with a number of NB LT cards as well as several ISAM-V distributed nodes (i.e. accessible via a common EMAN) with a number of NB LT cards

• All User Port in one NB LT are controlled from the same IVPSNote: Although it is not a system constraint, the network deployment should be planned so that all user ports in one shelf are associated to/ controlled by only one IVPS. This is recommended for two different reasons:

• simplest network architecture with an easier operation• to keep compatibility with further features in order to limit the bandwidth/number

of calls per shelf• The different traffic flows related to voice service are isolated into different

VLANs which are defined over the EMAN and in the ISAM SHub:• Voice VLAN:

RTP traffic and XLES signaling is carried over this VLAN• MEGACO VLAN:

for MEGACO signaling traffic between CS and the media GW and SIGTRAN signaling between ASP and the signalling GW

• External OAM VLAN:for provider operation and management

• Both hub and subtending (cascading or remote (distributed)) configurations are possible. In cascading configurations, the connection to the hub is via Fast or Gigabit Ethernet (optical or electrical) to the SHub of the hub node.

IVPS

The IVPS communicates with the voice line boards by means of an “extended BLES” (XLES) proprietary protocol. The IVPS terminates the proprietary signaling messages from the voice boards, provides a MEGACO interface with the call server and handles the specific OAM needed to support VoIP service.

The IVPS functions are:

• The signaling interface with the call server or soft-switch (MEGACO signaling)• Internal proprietary protocol (XLES) for signaling supervision and control with

POLT line termination boards• Digit Map processing (either under Megaco reception or by CDE data)• Specific OAM interface needed to support VoIP configuration and service• Persistent storage of the voice service database including back-up and restore• Regarding ISDN signaling:

• IVPS performs message relay between the DSS1 XLES messages containing Q921 and the IUA over SCTP messages that carry the Q931 info towards the ASP.

• IVPS relies the ISDN signalling packets (DSS1) from/to UDP-XLES socket and translates those related to Q921 info (SAPI, TEI) to/from IUA/SCTP.

• Q931 layer is not processed by IVPS or BALT, but transparently sent/received as SIGTRAN packets information to/from the Call Server.

• Configuration data:IVPS stores the L1 activation type (per-call or permanent) for each port. When the communication with a BALT is established, IVPS sends this information to BALT.

POLT

The POLT supports up to 48 POTS interfaces and integrates functions such as ringing, digit detection and tone generation. The POLT provides a classical POTS interface towards the subscriber and performs the packetization of the voice over RTP, sending the voice directly to the network as VoIP over Ethernet.

This is the analogue Z interface connecting to a telephone set. The main common features are the following:

• Interfacing at subscribers side according to the POTS analogue Z interface:• Line feeding• Symmetrical programmable ringing• Polarity reversal• Programmable line impedance with echo cancellation• Overvoltage protection

• Signaling events processing and communication with IVPS according to internal XLES protocol

• DTMF/pulse detection/processing• Caller identification services (FSK, DTMF, on-off hook)• Tone generation towards subscriber side• Howler tone generation• Tone generation towards network side (needed for ring-back tone)• Metering pulses generation



• Ringing generation.• Integrated line testing• Coding (G.711 and either G.729 or G.723.1) and packetizing voice in RTP and

directly forwarding to/from packet network based on MAC/IP/UDP addresses• Voice activity detection, comfort noise, packet loss concealment• Near end echo cancellation• Fax/modem detection/bypass• Support of relay of DTMF and some fax/modem tones by means of RFC 2833

BALT

The interface of the BALT corresponds to the U reference point of the Digital Transmission System as defined in G.961.

The interface provides full-duplex and bit independent transmission via two wires at a net bit rate of 144 Kbit/s, a transparent 1 Kbit/s service channel and a 1 Kbit/s maintenance channel for loops and error messages on subscriber lines, plus synchronization bits.

Duplex transmission is achieved through the use of Echo Cancellation Hybrid. With the Echo Cancellation Hybrid method the Echo Canceller (EC) produces a replica of the echo of the transmitted signal that is subtracted from the total received signal. The echo is the result of imperfect balance of the hybrid and impedance discontinuities in the line.

The 2B1Q encoding is applied; the symbol rate on the line is therefore 80 KBaud.

In the case of ISDN BA over IP, the functionality is split between the BALT line board and the IVPS board. The BALT board supports 24 ISDN BA user ports and terminates Q.921 data links; IVPS establishes a SIGTRAN communication with the ASP. ASP is responsible for terminating IUA/SCTP and processing the Q.931 messages.

The BALT functions are:

• Line Termination for the U interface of ISDN Basic Access ITU G.961• G.711 (A,µ), G.729a/b, G.723.1 coding• Local Echo cancellation (G.168, G.165, none) 16 ms. tail length• Voice activity detection, comfort noise, packet loss concealment• Configurable jitter buffer: adaptive or fixed size (per call)• Automatic fax/modem detection and bypass (transparent fax and modem service)• Enhanced end-to-end tone detection and generation (as per RFC 2833)• Call progress tone generation: Dial Tone, Special (Information) Dial Tone, Ring

Back Tone, Congestion Tone, Busy Tone



• DTMF digit detection: when a call is in stable phase and the user sends DTMF digits to, for example, an automatic Call Centre, the BALT must detect the DTMF.

• Support for duplication of RTP streams for future Lawful Interception implementation

• Regarding ISDN signaling:• Termination of Q921 protocol (SABME,UA, RR,..., timers, states,...)• BALT establishes, releases and maintains data links with TEs as specified in Q.921.

For this, BALT controls LAPD sequence numbers, maintain Q.921 state machines, etc. There is one established data link for each TEI.

• There is one data link established between BALT and IVPS. XLES for POTS is transported inside that data link.

• Dynamic TEI assignment is done by BALT• The ASP (through IVPS) may command the removal of a particular TEI. BALT

carries out this action and notifies it to IVPS. Also, ASP may ask for TEI status.

Integrated Line TestingThe integrated Line Testing functionality can be used by the operator in order to detect failure conditions and anticipate possible problems.

Note: Only line testing of POTS line terminations can be tested.

Tests can be performed on demand (required by an operator command).

The following test can be performed:

• Electrical measurement test:The purpose of these tests is the measurement of electrical parameters. These tests do not require customer assistance. Any or all of these tests can be invoked in the same test request for a given user port. Electrical measurement tests are:

• Foreign voltage (AC/DC): This test is measuring foreign voltage between wires.• Capacitance: This test is measuring capacitance between wires.• Insulating resistance: This test is measuring insulating resistance between wires.• Impedance: This test is measuring the impedance between wires.• Termination (M Socket detection): This test is to detect whether a phone or just a

resistance connects the line.• Feeding voltage: This test is performed measuring voltage over wires in open circuit

and verifying voltage remains within thresholds.• Feeding current: This test is performed connecting a resistor loading the wires and

measuring the current in limiting mode.• Noise level: This test is to detect abnormal noise level, e.g. crosstalk



• Group test:This test consists of a combination of predefined electrical measurements requested by the OS as previous electrical measurement tests. It includes a combination of voltage, capacitance and insulating resistance measurements. It can be performed on ISAM-V devices in 10 s. Thirteen possible measurements are:

• AC Foreign voltage: a/Earth, b/Earth and a/b• DC Foreign voltage: a/Earth, b/Earth and a/b• Capacitance: a/Earth with b grounded, b/Earth with a grounded and a/b• Insulation resistance: a/Earth with b grounded, b/Earth with a grounded, a/b and b/a

• Dial tone test:This test checks the ability of the line circuit to detect an off-hook and to check the provision of the dial tone from the MGC.An off-hook condition is simulated in the NE. This off-hook must be detected by the line circuit and is further processed by call-handling software; the MGC will then interpret it as a real off-hook and will send a dial tone. The time is measured and compared with a predefined threshold. Returned result is the delay to dial tone.

• Howler tone testThis test lets the user know that the mike is not hooked on correctly and restores the user state from parking to idle after the user hooks on the mike. If the user does not hook on the mike, the howler tone is stopped after a predefined timeout. The howler tone level and frequency depend on different countries’ specifications.

• Status monitorThis test lets the operator know the indicated user’s status.

2.1 General

Figure 2-1 shows the basic software architecture of the 7302 ISAM.

Figure 2-1 Basic 7302 ISAM Architecture

The 7302 ISAM software is composed of the following five top level software domains:

• Platform SoftWare (SW):Offers a robust platform upon which applications can be built, providing kernel and file system services, memory management, data management, an internal communication infrastructure,... Operating System (OS) dependencies are shielded by the XAPI OS shielding layer.

• HardWare (HW) Wrapper SW:Offers API’s that allow to access the hardware on the board, in such a way that hardware dependencies are isolated from the application SW.

• Core Services SW:Offers services that can be reused by typical applications in the 7302 ISAM, such as Alarm Management, Performance Monitoring Handing, and so on.

• Management Protocol SW:Offers the management protocols framework including Simple Network Management Protocol (SNMP) / Transaction Language One (TL)1 / Command Line Interface (CLI) management SW, transaction control management, and so on.

• Applications SW:The management applications in 7302 ISAM implementing the different product services and Management Information Bases (MIBs) of the 7302 ISAM.

2.2 7302 ISAM System Initialization

GeneralThis section describes the initialization of the 7302 ISAM.

After the SHub subsystem and the LT shelf subsystem are powered up, the boot sequence starts for each subsystem.

SHub Subsystem InitializationWhile booting, the SHub subsystem retrieves all necessary parameters from memory or from pre-configured defaults. A pre-defined OAM VLAN with VLAN ID (IC-VLAN= 4094) is fixed and cannot be used in the connected network because the value 4094 is reserved and may not be used externally. This internal OAM VLAN is also pre-defined in the NT-LT initialisation. This VLAN is used for the software download to the LTs and the configuration of the LTs.

If a configuration database was saved, and the SHub subsystem was set to restore this configuration before the last system down, the SHub subsystem will retrieve this configuration.

The SHub subsystem is now operational.

For more information, refer to the Operations and Maintenance Using CLI.

LT Shelf Subsystem InitializationSince the NT board is the system manager, it has the control over the system init phases of the LT shelf subsystem and is responsible for the sequencing of the initialization phases of the NT board and the rest of the 7302 ISAM. This is in contrast to the SHub subsystem which is initialized independently. The initialization of the LTs and the SHub subsystem happen parallel. However as long as the SHub subsystem is not up, the NT will not establish communication with the LTs. The NT software can check if the SHub subsystem is alive.

The LT shelf subsystem initialization consists of the following phases:

• Local NT initialization• System initialization• Enable external 7302 ISAM management

Local NT Initialization

The following phases are identified for the local NT initialization:

• Boot phase• Overall SoftWare (OSW) startup• Initialization phase• Restore data from non-volatile memory

In this phase the LT boards boot and wait for the NT board to get their OSW.



System Initialization

In the first phase of the system initialization, the NT board detects the LT boards, the ACU and the appliques (HW) and downloads the appropriate SW to the LT boards.

The LT boards start up with their SW and perform their specific initialisations.

After these initialisations, each LIM board sends a signal to the NT board. The second phase of the system initialization begins when the NT board receives this signal. Now the NT board configures each LT board.

Enable External 7302 ISAM Management

When the LT boards are configured, the 7302 ISAM management is enabled on the NT board and the 7302 ISAM indicates that the initialization is fully complete and the system is operational.

Note: For more information about the initialization and startup of the 7302 ISAM please refer to the Operations and Maintenance Using CLI.



2.3 Network Management

Figure 2-2 shows how the 7302 ISAM can be managed in a network.

Figure 2-2 7302 ISAM Network Management

The remote Craft Terminal (CT) uses TL1 commands or Command Line Interface (CLI) commands. TL1 is used for pre-provisioning of the NT board. CLI is used to manage both the SHub subsystem as the NT board.

Figure 2-3 shows the management topology for the two subsystems of the 7302 ISAM.

Figure 2-3 7302 ISAM Management Topology

Note: If the 7302 ISAM is configured to have only one public IP address, then the direct SNMP management interface to the SHub is no longer available. The SHub will then be managed through the SNMP interface of the NT.

The NT Controller and the SHub subsystem each contain a separate SNMP agent. The NT Controller / LIMs and the SHub subsystem can be managed via an EMS.

It is also possible to use local TL1 or CLI craft terminal on the NT board to manage the LTs.

An integrated CLI approach is implemented on the NT board using an CLI agent. This agent implements CLI commands for the NT Controller / LIMs and the SHub subsystem. However, there is no semantical integration.

Table 2-1 shows an overview of the managers which are involved:

Table 2-1 Manager Overview

Note: External OAM VLAN

The SHub subsystem supports inband management. This happens through a dedicated VLAN, which must be configured (if different than 4043) on both the SHub subsystem as on the NT.

3.1 Introduction

This chapter describes the different ISAM subrack types supported for the European Telecommunication Standard Institute (ETSI) market.

For each subrack, the following characteristics are described:

• Subrack dimensions• Physical areas• Slot positions• Supported plug-in units (per release).

3.2 General

The modular organization of the ISAM system allows a wide range of physical size and traffic capacity options.

The basic building blocks of the ISAM system are the subracks or shelves(*).

(*): Both names are used for the same item.

The ISAM R2.x is a one-subrack system. Daisy-chaining multiple shelves via Extender boards is not supported.

It is possible to cascade multiple collocated shelves via the standard Fast Ethernet (FE)/Gigabit Ethernet (GE) subtending links. In such a configuration, each subrack will operate and be managed as a separate system.

Subrack TypesTable 3-1 gives an overview of the supported subrack types in ETSI configurations. The subracks comply with the standards of ETSI 300 386.

Table 3-1 ETSI Subracks Supported in ISAM Configurations

Notes:

• (1): The 4-LT XD subrack (ARAM-D) is mentioned here for completeness sake. For more information about configuration and installation of the 4-LT shelf (ARAM-D), refer to the 4-LT Shelf (ARAM-D) Product Information.

• (2): The 4-LT XD subrack must be mounted vertically with mounting kit.

3 — Subracks

Board TypesThe XD-LT subrack can accommodate the following units (Figure 3-2):

• one Alarm Control Unit (ACU) plug-in board• two Network Termination (NT) boards• up to 16 LIMs:

Splitters for the xDSL LIMs can not be mounted in the XD-LT subrack and will be put in a separate subrack.

• one NT I/O applique:This applique is a full size board which plugs into both NTIO connectors, located high in the DSL cabling area of the subrack.

• one SMAS board:This small board serves as a subrack identification resource. It is plugged into the backplane and is delivered as an integral part of the subrack.

Notes:

• No PWR I/O board is developed for the XD-LT subrack. The power connectors are available in the connector area.

• No specific Termination Plugs are supported for R2.5.

RestrictionsThe following restrictions apply:

• The XD-LT subrack is not equipped with a TEST/SPARE bus. When the 1:N LT redundancy and/or MTA functionality needs to be supported, the necessary provisions need to be available in the connected splitter device (refer to section 4.1.2).

• The XD-LT subrack will not be ready to support 72-line boards.

1+1 NT RedundancyNT redundancy is supported from R2.2 onwards (HW & SW). NT redundancy is supported in the following boards:

• ECNT-A• ECNT-C CB

1+1 LIM RedundancyThe backpanel is already provisioned to support the 1+1 LIM redundancy. The necessary will have to be mounted in the splitter subrack (XD-SP) since appliques cannot be mounted in the XD-LT subrack itself.

1+1 LIM redundancy is not a supported R2.x feature.

1:N LIMThe 1:N redundancy of the LIMs is not supported in the XD-LT subrack itself since no TEST/SPARE bus is available. When this functionality is required, the necessary provisions need to be available in the connected splitter device.

1:N LIM redundancy is not a supported R2.x feature.

LT Redundancy and Metallic Test Access SupportThe XD-SP subrack provides a Test/Spare bus on the backpanel for the support of 1:N LT redundancy and Metallic Test Access (MTA).

A dedicated slot (TAUS) is foreseen for a Test-I/O Applique. A SPI bus connects this slot with the 16 splitter slots to allow control of the relays on the splitter boards.

Overview Supported UnitsTable 3-5 gives an overview of the supported plug-in units in the XD-SP subrack for R2.5.x. These units must be used in conjunction with the LT boards in the XD-LT subrack. Refer to Figure 3-4 for layout and slot positions.

3.5 XD Standard Splitter Subrack (ASPS-C)

The XD-LT subrack is splitterless. Therefore, the splitter appliques for the LT boards need to be housed in a separate subrack. The XD-PSP subrack is a cost-improved version of the XD-SP subrack. The main characteristics of this new subrack type are:

• The subrack has no backplane will be equipped (no MTA support, no LT redundancy support).

• The subrack can house up to 16 xDSL line boards. Each board is able to handle 48 lines.

• The subrack can be mounted in the existing ETS rack frame of an XD Modular system (above the XD-LT subrack) or in a standard 19” rack. By re-orienting the mounting brackets, the subrack can be mounted in frames.

The XD-PSP subrack is supported from R2.2 on.

MnemonicThe mnemonic is ADSL SPlitter Subrack version C (ASPS-C).

3.6 XD-Combo300 Subrack (ALTS-U)

The XD-Combo300 (ISAM V) subrack contains LT functions as well as splitter function. This subrack is intended mainly to be used for POTS+ADSL combo applications.

The XD-Combo300 subrack uses the backplane approach. The connector area of the XD-Combo300 subrack is dimensioned to house only one row of CHAMP connectors, therefore two CHAMP connectors (occupying two slots) are needed for a 48 line set (see Figure 3-7).

The XD-Combo300 subrack is supported from R2.3 on.

MnemonicThe mnemonic is ADSL Line Termination Subrack version U (ALTS-U).

Dimensions Figure 3-7 shows a front view .

Board TypesThe XD-Combo300 subrack can accommodate the following units (Figure 3-8):

• one ACU plug-in board• two NT boards• up to 8 POTS / xDSL LT board pairs in combo function, occupying 16 slots (one

slot per LT board and 2 slots for POTS / xDSL board pair).• up to 8 splitter appliques for the xDSL / POTS LIMs occupying 16 slots (each

applique is double wide slot for 48 subscriber lines).• one NT I/O applique with interfaces to the NTs• one TST I/O applique for tests• one PWR applique.• one termination plug board. It is plugged into the backplane and is delivered as

an integral part of the subrack.

Notes:

• The XD-Combo300 subrack is equipped with a TEST/SPARE bus and 1:N LT redundancy and/or MTA functionality needs can be supported.

• The XD-Combo300 subrack is ready to support 48-line boards.

1+1 NT RedundancyThe backpanel is ready to support NT redundancy.

NT redundancy is supported from R2.2 onwards (HW & SW). NT redundancy is supported in the following boards:

• ECNT-A• ECNT-C CB

1+1 LIM RedundancyThe backpanel is already provisioned to support the 1+1 LIM redundancy.

1+1 LIM redundancy is not a supported R2.x feature.

1:N LIM and Metallic Test AccessThe XD-Combo300 subrack provides a TEST/SPARE bus on the backpanel for the support of MTA and 1:N redundancy. If these functionalities are required they have to be supported in the appliques also.

1:N LIM redundancy is not a supported R2.x feature.

Local Loop UnbundlingThe Local loop Unbundling (LLU) function depends on the used applique

• for PSPS-E: the LLU function allows to disconnect the xDSL line from the loop while the LPF function in the line is bypassed.

• for PSPF-B: the LLU function allows to disconnect the LPF function from the POTS LT and connect it to the POTS connector on the front of the PSPF-B applique.

LLU is supported from R2.2 onwards (HW & SW).

5.4 XD-Combo300 Rack Configurations 5-7



5.1 Introduction

This chapter describes the possible rack configurations for ISAM R2.5.

5.2 Rack Configurations

The following applies for rack configurations:

• An XD Modular rack contains only XD-LT , XD-SP and/or XD-PSP subracks.• A XD-Combo300 rack contains only XD-Combo300 subracks.

ISAM LocationThe ISAM configurations described can be installed in various locations: conventional CO , CEV or remote cabinets.

Note: The XD-Combo300 configuration can only be installed in a CO location.

Subrack Type IdentificationThe subrack type is defined by four bits identifying the BackPlane TYPe (BP-TYP) and four bits identifying the NT SLOT_ID (bits 4 to 1). This Physical Location IDentification (PLID) and the NT SLOT_ID are hardcoded, Table 5-1 gives an overview.

Table 5-1 BackPlane TYPe (BP-TYP) and SLOT_ID Setting

Equipment PracticeThe equipment practice applied is defined by Rack TYPe (R-TYP) identification bits. This PLID setting is done with jumpers on the backplane and can be checked by software. Table 5-2 gives an overview.

5.3 XD Modular Rack Configurations

General ConfigurationAn XD Modular rack contains:

• A 2200 mm rack cabinet• A TRU providing:

• Termination of redundant 48 or 60 Vdc battery power provided from the Power Distribution Frame (PDF) in the Central Office and power distribution to one or two subracks and accompanying fan units (splitterless subrack only)

• Over-current protection for each of the subrack feeds (field replaceable, 25 A circuit breakers)

• Termination of the alarm cable from each subrack• A termination point for the CO/CEV alarm cable and the rack alarm cable• An ADSL Top Rack Unit (ATRU) board with alarms displaying power alarm

conditions.• Power cables for two subracks, even if the rack contains only one subrack (this is

to avoid difficulties when adding subracks afterwards for a rack upgrade).• One or two subracks, equipped with plug-in units (see Rack Configurations for

the different possible combinations).• An ADSL FAN (AFAN) unit (one per equipped subrack) with eight fans

providing equipment cooling and (optionally) equipped with a dustfilter.Note: Only the subrack in the lower position is equipped with a fan unit with dustfilter, the subrack in the upper position is equipped with a fan unit without dustfilter (refer to Table 5-3).

• One ACU cable per equipped subrack.



Rack ConfigurationsEach “ADSL Line Termination Rack” (ALTR) configuration is defined by a FEMA mnemonic and code, Table 5-3 gives an overview of possible configurations. Figure 5-1 shows the layout of the different configurations.

5.4 XD-Combo300 Rack Configurations

This section describes the rack configurations, both general and specific for the XD-Combo300.

General Rack ConfigurationAn XD-Combo300 rack contains:

• A rack cabinet: 2200 mm high.• A door opening/closing on the left or the right side with a handle or a lock.• A TRU (on top in the rack) with:

• A power input block for connection of CO supply cables and distribution to one or two subracks and accompanying fan units.

• Protection devices (depending from the type of powering):- Circuit Breakers (CB) for rack or subrack powering- Switches (SW) for subrack powering- No protection devices for fixed subrack powering.

• An interface to CO/CEV alarm system.• An alarm interface to equipment inside the rack.• A LED display indicating rack alarm conditions.

• One or two subrack(s).• One ACU, located in the upper subrack and performing rack alarm and control

functions. When this subrack is the first of the ISAM, the ACU also provides local Craft Interface.Note: a rack with more than one NE has more than one ACU, the first subrack of each NE has its own ACU.

• One Fan unit per equipped subrack, for equipment cooling.The fan unit is a separate unit inserted in the subrack.The first subrack in an ISAM can contain an NT unit requiring a fan unit with twice as much fans for cooling.The fan unit in the lowest subrack is always equipped with a dust filter.

No LT boards are supported with optical interfaces, fiber handling does not pose any practical restrictions for the LTs.

Small Form PluggablesFor fibers directly connected to the NTs (where each NT supports three Small Form Pluggable (SFP) fiber interfaces), the following applies:

• SFPs with thin fibers (thin fibre cross-section = 1.3 mm):On the NT slots, a maximum of 16 thin fibers or 8 per NT can be wired. So no restrictions to support the maximum of 2 NT x 3SFPS/NT x 2 fibers per SFP = 12 thin fibers

• SFPs with standard fibers (standard fibre cross-section = 3 mm):The limit of 4 standard fibers that can be wired for the sum of the 2 NT slots gives a restriction: that is, maximum 2 SFPs with standard fiber for the sum of 2 NTs.

The supported SFP pluggable optical modules are listed in the table below.

6.5 1+1 NT Redundancy Support

The NT Redundancy feature is supported from R2.2 onwards.

Four levels of redundancy can be identified:

• Link redundancy• Equipment redundancy• Subscriber Line redundancy• Application redundancy

NT redundancy will implement the Link Redundancy and Equipment Redundancy in a decoupled architecture. This results in the following redundancy cases:

• Only link protection:single NT, active-standby or load-sharing uplinks.

• Combined NT and link protection, no NTIO:dual active/standby NT, with direct uplink or link set.

• Decoupled NT and link protection, single NTIO:dual active/standby NT, NTIO board with link switches.

• NT protection, passive link protection, no NTIO:single, active-standby or load sharing uplinks.

• Subtending System protection.

6.6 MTA and 1:N LT Redundancy Support

This section describes which hardware modules are required to support the various MTA functions and 1:N LT Redundancy.

ISAM R2.5.x does not support 1:N LT redundancy. The remainder of this section will therefore focus on MTA.

The ISAM system provides an integrated Metallic Test Access Unit (MTAU) function. Both limited test-access (no test and split access) and Full test-access (no test, loopback, monitor and split access) are supported in ISAM R2.5.

The following modules are required to implement the MTAU function:

• NT-I/O board in XD-LT/Combo subrack:to provide the (hardened) interface for communication between the NT and the Test-I/O applique in the splitter subrack (TAUS unit). The following NT-I/O board types support this functionality: ECNC-A, ECNC-B and ECNC-C.

• Test-I/O applique (TAUS) in the splitter subrack:to provide the interface to the test head and manage the Relay Controllers on the LT appliques. The following Test-I/O board types support this functionality: TAUS-A.

• The Test/Spare bus to provide (test or protection) access to a selected line.This spare bus is implemented on the backpanel of the XD-SP subrack and in the XD-Combo300 subrack.

• LT appliques in the splitter subrack, that contain the relays to set up the proper data paths.

Table 6-4 shows for all supported LT appliques in how far MTA (SW and HW functionality) and 1:N redundancy (HW functionality only) is supported.

Splitters supporting only outward test-access are equipped with only 1 relay per line, while splitters supporting both inward and outward test-access have 2 relays per line.

Table 6-4 MTA/1:N Redundancy Support for LT Appliques

Note: In case of the XD-Combo 300 subrack, the subrack is HW ready to support MTA and 1:N redundancy by integrating SPI interface per slot between the LT and applique areas, and the test / spare bus.

DHCP Dynamic Host Configuration Protocol

DHCP is a client/server service that is an extension of the BOOTP protocol. DHCP simplifies the configuration of a client workstation since no IP addresses, subnet masks, default gateways, domain names, or DNSs must be programmed. With DHCP, this information is dynamically leased from the DHCP server for a predefined amount of time. Because the information is stored on a server, it centralizes IP address management, reduces the number of IP addresses to be used, and simplifies maintenance. RFC 2131 defines DHCP.
