Preface

Purpose The purpose of the alarm dictionary is to provide the operator with a structuredmethod for handling alarm messages generated and reported by the 9125Transcoder.

This document contains a list of all 9125 Transcoder reported, and the actionsrequired to nullify them.

Alarms are displayed at the OMC-R terminal and at the LMT to inform theoperator of system faults.

Note: When a fault occurs, a number of alarms can be generated simultaneously.These alarms must be analyzed as a group to determine the precise fault.

What’s New In Edition 02The following alarms have been added:

[66,22] LOOP-TO-EQUIP (Section 2.1)

[66,50] TWO-MB-MISSING (Section 2.2)

[66,66] AIS-2-MB (Section 2.3)

[66,237] E1-BER-10E-6 (Section 2.18)For alarm class 66, alarms from 231 to 237 and for alarm class 105 theperceived security field was completed.

In Edition 01First official release of document.

1 Introduction

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

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

Each definition describes the:

Alarm definition

Alarm description

Impact on System

Methods for further fault isolation

Corrective actions.

1.2 A1353-RA AS Alarm InformationIn the A1353-RA OMC-R, Alarm Surveillance provides an efficient means tocontrol, supervise and manage equipment problems in the BSS.

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.

1.2.1 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.

1 Introduction

1.2.2 Alarm Type

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

This information is sub-divided into:

eventType. Table 1 describes the five eventTypes.

probableCause

perceivedSeverity: gives the severity level of the alarm. Table 2 describesthe severity levels.

eventType 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 1: Event Types

Severity Level Indicates...

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

Major a fault condition which requires urgent corrective 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 2: Alarm Severity Levels

In addition to 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

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

Depending on the type of alarm and where it is viewed, an alarm messagecontains all or most of the parameters listed in this section.

1.3.1 Message Identity

The identity number given to the alarm message stored in the OMC-R database.

1.3.2 Event Time

The time the message was issued at its source or received at the OMC-R.

1.3.3 Location

The origin of the alarm, consisting of:

Network element - the BSS identity

Unit type:

bts

bsc

tcsm

bie

tsc

bss.

Unit number:

0 or 1 for a tcsm

0 to 40 for a bie

1 for a bsc, tsc or bss

1 to 40 for a bts.

SBL type

SBL number and subnumber, if appropriate. For example, RTS (3, 4) is RTSnumber 4 of FU3 (the parent SBL).

1 Introduction

1.3.4 Classification

The characteristics of the alarm, consisting of:

Alarm Class name and number - as shown in the Contents list of the

Alarm Dictionary

Alarm Type name and number - as shown in the Contents list of 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. The

affected SBL may not change state if other alarms related to theSBL 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.

If 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.

1 Introduction

1.3.5 SBL States

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 Operations & Maintenance Principles for a description of the states.

1.3.6 RIT List

The information for the suspected RIT(s) is displayed if the system is able todetermine the location of the fault.

The information consists of:

Unit type - bts, bsc, tscm, bie, tsc or bss

Unit number -

0 or 1 for a tcsm

0 to 40 for a bie

1 for a bsc, tsc or bss

1 to 40 for a bts.

Physical location - the position of the RIT board within the cabinet. For

example, [A, 4, 21] indicates the board in slot 21 of rack 4 of cabinet A.For BSC and BTS equipment, the cabinets are identified as 1, 2, 3, etc.

instead of A, B, C, etc.

RIT type - the name of the RIT board.

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.

1.4.4 Alarm Description

1.4.4.1 Alarm DescriptionThe Alarm Description describes the alarm and, where appropriate, thedifferences to the default perceived severities.

1.4.4.2 Impact on TelecomThis field describes the impact on the Telecom system behavior. It alsocontains a table indicating which part of the system is affected by the fault interms of loss, degradation or none.

For example, if a cell is affected, the cell column in the table contains a tick ( ) ineither the Loss or Degradation row. The tick can be doubled in any one column( ), indicating the primary impact of the alarm. If the column has a tick in theNone row, that part of the system is unaffected by the fault. For different impactcases (redundancy, diversity, etc.) more symbols, like ladders (#), are used.

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

1.4.4.3 Impact on SystemThe impact on the system is defined in terms of Telecom and/or O&M.;

1 Introduction

1.4.4.4 Failure Identification StrategySometimes more information is necessary to determine the precise fault. TheFailure Identification Strategy lists the checks and tests to perform to obtainthis information.

The additional data is gathered from:

Diagnosis/tests to be applied - appropriate on-site or remote diagnostic and

test procedures to perform

Complex system alarm correlation - other checks that can provide moreinformation about the fault.

Checks that determine whether:

The failure is provoked by a problem external to the reporting unit

Multiple or repetitive failures are reported by one or more similar SBLs

The performance of the affected subsystem is degraded. Newperformance measurements can be compared with previous

measurements.

Resource and data verification - checks that determine whether:

Hardware is serviceable or available. The items checked are passive

items, such as cables, links and boards that do not report their state, andempty slots in subracks

Software versions and parameter settings are correct.

1.4.4.5 Corrective ActionsA description of the recovery actions to be performed by the operator ormaintenance staff. The recovery actions are based on the information providedby the alarm message or the results of diagnostic actions.

To solve the alarm, a graphical flowchart is used. It shows the required checks,tests and actions to be performed to determine the fault and to solve thealarm. The figure below shows an example of a flowchart and describesthe different flowchart fields.

Click on a dedicated action field to display the detailed description of the task.

Some alarms provide additional information. If it is displayed as a text message,the original information from the BSS has been decoded.
