1.3 9153 OMC-R Alarm Surveillance InformationIn the Alarm Surveillance of the 9153 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. FM displays informationas described below.

1.3.1 Object IdentificationThe 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 boards location by rack, shelf and slot. For BTS 9100 outdooronly: 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 TypeThe 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 FM on-line help for moredetailed information on FM.

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 NEM User Guide.

1.4.1 BTS LMT Alarm Message ParametersDepending 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 toFLT or FOS. For non-fatal failures, the affected SBL changes state to FITend - alarm off. Indicates the successful recovery of the system. Theaffected SBL may not change state if other alarms related to theSBL are onevent - occurrence of anomaly. No action is required unless it occursfrequently. Event alarms are of short duration and the affected SBLdoes not change state. The system retry/recovery mechanism hascleared 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.

14 / 320 3BK 21625 AAAA PCZZA Ed.06

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 SBLs 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 9100 outdoor BTS only: If thealarm 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 NEM, the additional information consists ofnumbers in the range 0 to 255. Each number represents the contents of onepair of digits.Decoding additional information digits is described in section 10 .

Decoding Additional Information from AlarmsDecoding BTS or BSC additional information must only be attempted byAlcatel-Lucent 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-Lucentsupport office.

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 DefinitionThe 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 requiredto 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. Thisseverity 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 severityis 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 correctiveaction should be taken in order to prevent a more serious fault. This severityis reported, when the detected alarm condition is not currently degrading thecapacity of the managed object.

3BK 21625 AAAA PCZZA Ed.06 17 / 320

1 Introduction

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

Cleared: indicates the clearing of one or more previously alarms for thismanaged object with the same Alarm type, Probable Cause and Specificproblems (if given).

1.5.2 Alarm Description1.5.2.1 Banner

Each 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 Informationsection BTS Alarm Additional Information (Section 10) 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 Alcatel-Lucentsupport personnel.If a fault persists after corrective actions have been taken, send a copy of thealarm message containing the additional information to the Alcatel-Lucentsupport office.

perceived Severity Major (PMA), Minor (DMA)

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.BTS 9100: There is no clock redundancy available, so the cells fed by the reporting CLLK are lost, thusthe BTS is lost.

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.

If the CLLK is redundant on this BTS, the telecom functions are not affected.For the BTS 9100: there is no clock redundancy available, so the cells fed by the reporting CLLK arelost, thus the BTS is lost.

perceived Severity Nbr 1: Major (PMA))Nbr 3, 4: Minor (DMA), Warning (MI)

Alarm Description There is a scenario-failure for TRANS&CLOCK.

Alarm Number 1 : An error in the initialization or re-configuration is detected, due to theabsence of an answer to the message "OMU, UNKNOWN_MESSAGE,inconvenient sub-state".3 : A SW downloading or SW activation failure is detected by theOMU, due to the absence of an answer to the message "OMU.UNKNOWN_MESSAGE, inconvenient sub -state". This alarm is not fatalbecause the TRANS&CLOCK uses the previous SW.4 : A transmission configuration failure is detected by the OMU due to noanswer to the OMU, an UNKNOWN MESSAGE or an inconvenient substate.This alarm has no fatal consequences, because the TRANS&CLOCK willuse the previous transmission settings.

If the CLLK is redundant on this BTS, the telecom functions are not affected.For the BTS 9100: there is no clock redundancy available, so the cells fed by the reporting CLLK arelost, thus the BTS is lost.

Alarm Description There is a scenario failure for TRE.An error in the initialization is detected due to no answer to OMU,UNKNOWN_MESSAGE, inconvenient sub-state.

The TRE is no longer usable. The associated eight channels are lost. Independent of frequency hoppingor not, the BSC reduces the number of channels supported by the cell.If the TRE supporting the BCCH is not concerned, the cell is degraded, calls are lost. (#).If the TRE supporting the BCCH is concerned and there is BCCH redundancy, recovery mechanismsregain the cells functionality, calls are lost.
