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. 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 9100 BTS outdoor
only: If the alarm message displays the RIT location A,0,0, the RIT islocated in the COMI/CODI side compartment.
14 / 582 3BK 21225 AAAA PCZZA Ed.10
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 Introduction
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.
16 / 582 3BK 21225 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,defined for the rack, shelf and slot. For 9100 BTS outdoor 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-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 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 21225 AAAA PCZZA Ed.10 19 / 582
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 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.

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 software is corrupted or bad.
Alarm Number 1: Error detected during the configuration with saved parameters ininitialization state: saved parameters are corrupted and cannot be used forthe auto-restart sequence.
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.
If the CLLK is redundant on this BTS, the telecom functions are not affected.
For the 9100 BTS: 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 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 9100 BTS: 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.

8.1 [7,1] AL-LIST-ER
specific Problems AL-LIST-ER
event Type Processing Error
probable Cause Software Error
perceived Severity Warning (MI)
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.
Telecom functions are not affected.

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.

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].
9100 BTS/9110 Micro BTS/9110-E Micro BTS : External alarm (e.g., dooropen, fire, water) detected from input port [1 ... 24].
External alarms [25 ... 56] can be raised only by the 9110 Micro BTS-E,and are applicable 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 9100 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.

Alarm Description The Lapd channel RSL between BSC and BTS TRE is faulty.
This can be due to transmission problem or to BSC TCU unavailability(faulty or operator disabled). In this situation, the TRE performs anauto-restart after having run a timer (BCCH_CUT_Timer).
The concerned TRE does not carry traffic as long as the Lapd RSL is not reestablished.

4: The antenna VSWR circuitry is defective.
5: A non-fatal fault has been detected on LNA 1 with 6 dB less gain on RX1.
6: A non-fatal fault has been detected on LNA 2 with 6 dB less gain on RX2.
7: A fatal fault has been detected on LNA 1: RX1 is lost. Consequently,antenna diversity is lost.
8: A fatal fault has been detected on LNA 2: RX2 is lost. Consequently,antenna diversity is lost, if used.
9: A HW failure is detected by auto-test, either in initialization state or infault localization state, or by selftest in initialization state.
11: The module is in operational state but faulty, the Local Recovery Actionfailed.
13: The AGC can not reach the LNA module. (This alarm is not reportedby ANX/ANC modules.)
Alarm Numbers 3, 4, 5, 6, 9, 11: There is no disturbance of the telecom application.
Alarm Numbers 7, 8: The antenna diversity is lost and the quality of reception is degraded.
Alarm Number 13: As the communication with the LNA is not possible, there is no information about thestatus available. If the LNA is still working, the telecom is not impacted. If there is no gain, telecom is atleast degraded.

(1) As this alarm is fatal for the module, no alarm disappearance indication issupplied. The alarm disappearance is detected on Alarm In Force List report.
(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).

Variable Results (maximum length is 40 bytes).
Table 26: TLV61 Bytes
(1) For TRE, only one byte is forseen, because the length of the data is <127 bytes.
TLV61, even if indicated, may not appear in an alarm message. Internal FUproblems, such as a blocked internal bus or a hardware fault, can prevent theFU controller from receiving it. Several TLV61s can be sent.
The definition of the Board Identification bytes for G1, G2 and Micro -BTS isshown in Table 27. A bit set to 1 identifies the board at the origin of the faultdetection.
