1.1 OverviewThis alarm dictionary provides additional information that is not displayed in thealarm messages sent to the OMC-R, BSC or TSS terminals.

The dictionary contains alarm definitions for each alarm type produced bythe BSS.

Each definition describes the:

Alarm description

Impact on System

Methods for further fault isolation

Corrective actions.

The descriptions of the alarms in this document is MO based for OMC -Rterminal purpose. For BTS LMT purpose, the SBL related information isadded in brackets if applicable.

1.2 Relationships Between SBLs and MOsThe BSS generates SBL based alarm indicators. For the A1353-RA purpose,this information is translated into MO format.

This section defines the relationships between SBL and MO formats.

1.2.1 SBL State to MO State Translation

The SBL state is translated into a related MO status according to following table:

1.3 A1353-RA Alarm Surveillance InformationIn the Alarm Surveillance of the A1353-RA OMC-R efficient means to control,supervise and manage equipment problems in the MFS are provided.

Alarms or Alarm notifications consist of messages sent by network resourcesthat have detected problems or failures in the network. These alarms aredisplayed in lists while alarm counters keep track of statistics. By clicking on analarm in the list, the operator gets detailed information. AS displays informationas described below.

1.3.1 Object Identification

The Object Identification identifies the resource that raised the alarm.

Object identification gives information about:

The resource type (Object Class)

The resource name (Friendly Name). For a board, the Friendly Name alsoshows the board’s location by rack, shelf and slot. For BTS A9100 outdoor

only: If the alarm message displays the RIT location A,0,0, the RIT islocated in the COMI/CODI side compartment.

1 Introduction

1.3.2 Alarm Type

The Alarm Type identifies the type of problem the alarm refers to.

This information is sub-divided into:

evenType. Table 3 describes the five evenTypes

probable Cause

perceived Severity: gives the severity level of the alarm. Table 4 describesthe severity levels.

evenType Indicates....

Communication a problem with a procedure or process used to convey information fromone point to another in the network.

Quality of Service degradation in the quality of service in the network.

Processing Error a software or processing fault.

Equipment an equipment fault.

Environmental a problem in the enclosure containing the equipment.

Table 3: Event Types

Severity Level Indicates...

Critical a serious fault condition which requires immediate corrections. Example: amanaged object goes out of service.

Major a fault condition which requires urgent correction action. Example: severedegradation in the operation of a managed object.

Minor a fault condition which does not affect service but corrective action shouldbe taken to avoid a more serious fault.

Warning detection of a potential fault condition. Action should be taken to diagnoseand correct the problem to avoid a more serious fault condition.

Indeterminate the severity level cannot be defined by the resource which raised the alarm.

Cleared the alarm was cleared by the resource which raised the alarm.

Table 4: Alarm Severity Levels

In addition the Object Identification and Alarm Type information, all alarmsalways give the date and time of the alarm. An alarm may also contain optionalinformation, such as the notification id. Refer to the AS on-line help for moredetailed information on AS.

1.4 LMT Alarm MessagesThe format of Alarms displayed at a LMT differs from that in the OMC-R.

For more information about the BTS LMT see BTS Terminal User Guide.

1.4.1 BTS LMT Alarm Message Parameters

Depending on the type of alarm and in which window it is viewed, an alarmmessage contains all or most of the parameters listed in this section.

1.4.1.1 Message IdentityThe identity number given to the alarm message stored in the database.

1.4.1.2 Event TimeThe time the message was issued at its source or received at the BTS LMT.

1.4.1.3 ClassificationThe characteristics of the alarm, consisting of:

Alarm Class name and number - as shown in the Alarm Dictionary

Alarm Type name and number - as shown in the Alarm Dictionary

Alarm Number - dependent on the Alarm Class and Type. See theappropriate dictionary entry for the valid alarm numbers for a particular alarm

Alarm Condition - has one of the following values:

begin - alarm on. For fatal failures, the affected SBL changes state to

FLT or FOS. For non-fatal failures, the affected SBL changes state to FIT

end - alarm off. Indicates the successful recovery of the system. Theaffected SBL may not change state if other alarms related to the

SBL are on

event - occurrence of anomaly. No action is required unless it occurs

frequently. Event alarms are of short duration and the affected SBLdoes not change state. The system retry/recovery mechanism has

cleared the fault.

1.4.1.4 LocationThe origin of the alarm, consisting of:

Unit type

Unit number

SBL type

SBL number and subnumber, if appropriate.

24 / 584 3BK 20925 AAAA PCZZA Ed.10

1 Introduction

1.4.1.5 SBL StatesIf a fatal alarm occurs and the affected SBL changes state to FOS, the systemisolates the faulty equipment if it cannot be initialized. After a repair action, theoperator normally initializes the equipment.

If a fatal alarm occurs and the affected SBL changes state to FLT, the systemresets the faulty equipment. When the alarm ceases, the system automaticallyinitializes the equipment.

If a non-fatal alarm or event occurs, the affected SBL’s are put into the FIT state.In the worst situation, the equipment operates in a degraded mode.

An SBL has one of the following (current) states:

IT

FIT

Faulty

EF

FOS

OPR

SOS

WTC

UT

NEQ

MSD

MSD AUTO

Refer to the document Operations & Maintenance Principles for a descriptionof the states.

1.4.1.6 Suspected RITThe information for the suspected RIT is displayed if the system is able todetermine the location of the fault.

The information consists of:

Unit type

Unit number

RIT type

Physical location - the position of the RIT board within the cabinet, definedfor the rack, shelf and slot. For BTS A9100 outdoor BTS only: If the

alarm message displays the RIT location A,0,0, the RIT is located in theCOMI/CODI side compartment.

If more than one RIT is shown in the list, the RIT most likely to be causing thefault is indicated. Replace this RIT first and initialize it. If the fault persists,replace another RIT from the list and initialize it.

1 Introduction

1.4.1.7 Additional InformationSome alarms provide additional information. If the additional information isdisplayed as a text message, the original information from the BSS has beendecoded.

If the additional information is not decoded, it is displayed as pairs ofhexadecimal digits. At the BTS terminal, the additional information consistsof numbers in the range 0 to 255. Each number represents the contentsof one pair of digits.

Decoding additional information digits is described in section 13.

Decoding Additional Information from AlarmsDecoding BTS or BSC additional information must only be attempted byAlcatel support personnel.If a fault persists after corrective actions have been taken, send a copy of thealarm message containing the additional information to the Alcatel supportoffice.

1 Introduction

1.5 BTS Alarm InformationThis section describes the definition of alarms as they appear on the OMC-Rand the alarm description given in the document.

1.5.1 Alarm Definition

The alarms are defined as follows:

1.5.1.1 specific ProblemsThis parameter, when present, identifies further refinements to the probableCause of the alarm. It qualifies the chosen probable Cause and may beused by the managed object class to specify a set of identifiers for use inmanaged object classes. The parameter is either a set of integers or a setof object identifiers.

1.5.1.2 eventTypeThe eventType attribute identifies the basic type of the alarm.

It provides a list of standard types:

Communication: associated with the procedures and/or processes required

to convey information from one point to another.

Quality of Service: associated with a degradation of the quality of service.

Processing Error: associated with a software or processing fault.

Equipment: associated with an equipment fault.

Environmental: associated with a condition relating to an enclosure inwhich the equipment resides.

1.5.1.3 probable CauseThis attribute defines the probable cause of the alarm. Its value belongs toa set of possible values either defined in recommendation X.721, M3100and GSM 11.12 or defined for a particular Telecommunication ManagementNetwork (TMN) project.

1.5.1.4 perceived SeverityThis attribute defines six severity levels. The severity levels indicate how thecapability of the managed object is affected.

The levels are:

Critical: indicates that an immediate corrective action is required. This

severity is reported, when a managed object becomes totally out of serviceand its capability must be restored.

Major: indicates that an urgent corrective action is required. This severity

is reported, when there is a severe degradation in the capability of themanaged object and its full capability must be restored.

Minor: indicates a non-service affecting fault condition and that corrective

action should be taken in order to prevent a more serious fault. This severityis reported, when the detected alarm condition is not currently degrading the

capacity of the managed object.

3BK 20925 AAAA PCZZA Ed.10 27 / 584

1 Introduction

Warning: indicates a potential or impending fault, before any significanteffect have been felt. Action(s) should be taken to further diagnose (if

necessary) and correct the problem in order to prevent it from becoming amore serious service affecting fault.

Indeterminate: indicates that the severity level cannot be defined by the

resource raising the alarm.

Cleared: indicates the clearing of one or more previously alarms for this

managed object with the same Alarm type, Probable Cause and Specificproblems (if given).

1.5.2 Alarm Description

1.5.2.1 BannerEach BSS alarm definition starts with an identification banner which allows thelocation of the appropriate definition. It takes the form:

[7,246] FU CONFIG-FAIL

1.5.2.2 Alarm DescriptionAlarm Description describes the alarm and, where appropriate, the differencesto the default perceived severities and alarm numbers.

1.5.2.3 Impact on SystemThe description of the impact on Telecom and O&M system contains a tableindicating which part of the system is affected by the fault in terms of loss,degradation or none.

For example, if a cell is affected, the cell column in the table contains acheck (X) in either the Loss or Degradation row. For different impact cases(redundancy, diversity, etc.) other symbols are used.

The table shows the worst case, even though redundancy may be provided.

1.5.2.4 Corrective ActionsSo solve the current alarm a graphical workflow chart is used. It shows therequired procedures by checks, tests and actions to determine the fault andfinally to solve the alarm.

Checks, tests and thus resulting corrective actions are provided with apriority on remote at the OMC-R and then by service on-site, to minimize themaintenance effort.

By clicking on a dedicated action field, a link to the detailed description of thetask will be opened.

1.5.3 Additional Information

section BTS Alarm Additional Information (Section 13) describes the decodingof the additional information.

Some alarms provide additional information. If the additional information isdisplayed as a text message, the original information from the BSS has beendecoded.

If the additional information is not decoded, it is displayed as pairs ofhexadecimal digits. At the BSC terminal, the additional information consistsof numbers in the range 0 to 255. Each number represents the contentsof one pair of digits.

Decoding Additional Information from AlarmsDecoding BSC additional information must only be attempted by Alcatelsupport personnel.If a fault persists after corrective actions have been taken, send a copy of thealarm message containing the additional information to the Alcatel supportoffice.

Alarm Description Major (PMA)/Minor (DMA): Fault on the clock signals detected by severalclock users in the BTS (e.g. FHU, CU, FU).

Major (PMA): If the CLLK alarm disappears and the OMU loses the alarminformation, this alarm is sent by the OMU as a dummy alarm. It indicatesthat the CLLK is FOS and requires operator initialization.

If the alarm has unknown cause, it indicates that more detailed alarmswere reported before and are available at OMC-R.

If the clock system is redundant on this BTS, the telecom functions are not affected.

If, however, no redundancy is available, the channels supported by the CLLK/CLDB are lost.

Alarm Description The Clock Unit has performed an auto-reset, e.g. following the expiry of awatchdog timer during operational mode or due to a pushbutton reset.

If the clock system is redundant on this BTS the telecom functions are not affected.

If, however, no redundancy is available, the call(s) on that BTS are lost due to the lack of clock signals andare not resumed later. Signaling is resumed as soon as the Clock Unit is available again.

Alarm Description Major (PMA): The configuration/reconfiguration is not possible becausethe Clock Unit is not answering to commands.

Minor (PMA): No answer on the Q1 bus from a Clock Unit, for more thantwo polling cycles, to polling by the OMU.

Major (PMA): If the clock system is redundant on this BTS, the telecom functions are not affected.

If, however, no redundancy is available, the cell will be lost because no configuration can be set.




Minor (DMA): In case of Q1 malfunction there is no disturbance of the telecom applications.

In case of clock malfunction and the clock system is redundant on this BTS, there is no disturbance ofthe telecom application.

If, however, no redundancy is available, the result depends on the clock fault, the clocks can eventuallygo on with the previous configuration. If the fault is fatal, others alarms will appear on other equipment(ex FU on Token bus).

2: Error detected during the SW activation procedure in the fault localizationstate, or a check-sum error is detected in operational state.

3: A fatal exception has occurred on ŁP, or a ŁP SW error is detected in astate other than the operational state.

4: An error has occurred during the SW activation procedure, triggeredby the OMU in the initialization state. The alarm is not fatal because theTRANS&CLOCK uses the previous FW.

5: An error has occurred which is linked to a software download. Theerror was detected during the downloading procedure from the OMU ininitialization state (packet sequence, global file checksum). This alarm isnot fatal because the TRANS&CLOCK uses the previous FW.


For the BTS A9100: there is no clock redundancy available, so the cells fed by the reporting CLLK arelost, thus the BTS is lost.

The CU power supply is switched off because of the local retuning of thecavity.

If the retuning is not successful, the severity of the alarm changes to Minor(DMA). The CU power supply is switched off because of the couplingproblem.

Minor (DMA): The CU is no longer usable. The associated eight channels are lost. The BSC reduces thenumber of channels supported by the cell.

If the CU supported the BCCH, redundancy mechanisms regain the cell’s functionality, calls are lost.

If there is no BCCH redundancy, the complete cell is lost.

8.1 [7,1] AL-LIST-ER

specific Problems AL-LIST-ER




Alarm Description The FU internal alarms list is erased.

This alarm is caused by either:

an FU alarm overflow because OMU has not read FU alarms before theFU has reached its maximum storage for alarms

or loss of alarm list (as all other data) due to a hardware watchdog

(DRFU only)

If this alarm occurs consecutively, this can indicate OMU failure or externalFU link failure.

If there are no or few FU alarms the problem can be due either to:

fast external FU link toggling (appearance/disappearance)

an OMU problem in the reading of FU alarm (too slow).

The OMU recovers the FU internal Alarms in Force list autonomously.

Alarm Description A fault is detected on the BSI link by the FU. This alarm is given whenthe fault appears.

If the fault is present during more than one BSI_TIMER (FU TIMER), anOFF alarm is sent and alarm [7,6] is generated.

BSI link redundancy is not supported (only BSI link 0 is connected betweenBIE and BTS).

Telecom functions can be affected.

Disturbances are dependent of telecom mechanism (timers, protocol,...) and duration of the fault(maximum is fixed by BSI_TIMER).

For example, calls will be released if this fault lasts more than T_SYNC (FU timer) due to remotetranscoder alarm.

specific Problems EXT-ALARM




Alarm Description External Alarms are not linked to telecom part of the BTS, they are forseento announce events linked to the environment of the BTS.

G2 BTS: External alarm (e.g., door open, fire, water) detected from inputport [1 ... 24].

BTS A9100/A9110/A9110-E : External alarm (e.g., door open, fire, water)detected from input port [1 ... 24].

External alarms [25 ... 56] can be raised only by the BTS A9110-E, and areapplicable only in this case.

For Outdoor BTS, some of the 24 external alarms are allocated to thecabinet, they are already wired and reflect behaviour of other elements inthe BTS: AC main, Air Conditioning unit, door...

For A9100 Indoor BTS, the 24 external alarms are free (customer).

External alarms are seen only at the BTS and BSC terminals. At theOMC-R, they are translated into customer-defined ASCII text.

To simplify the external alarms declaration, default values are provided withan alarm translation table.

Telecom functions are not directly affected, if the detected problem is not disturbing the BTS function.

(#) VSWR and LNA alarms (if equipped), indicates a problem on the antenna output, and degradationmay occur.

(2) As the link connection is lost, the failure cannot be spontaneously reportedto the OMU/SUM. But the corresponding alarm is stored in the Alarms In ForceList and may be obtained by the OMU/SUM on Alarm In Force List report (if thefailure has disappeared), as long as the module stays in out of order state (asthe reason for which the OUT OF ORDER state has been entered).
