Definition of Routine Maintenance

Routine maintenance is a kind of active maintenance. It is

also called preventive maintenance or periodic

maintenance.

Routine maintenance is performed periodically during

normal operation of equipment, including daily, weekly,

monthly, quarterly, and yearly routine maintenance.


Objectives of Routine Maintenance

Remove potential risks to ensure the system works normally.

Ensure that the electrical performance, mechanical

performance, and various service indexes of equipment

conform to relevant requirements.

Guarantee the network runs normally by good coordination.

Make sure that the new equipment and expansion equipment

to be connected to the network correctly.

Alarm Type and LevelEvent AlarmFault AlarmRecovery Alarm

Critical LevelMajor LevelMinor LevelWarning Level


Alarm ID and Sequence NumberUsed to identify the sequence

of alarms generated.

Used to identify the

category of alarm


Current Alarm and History Alarm

Current Alarm: The current alarm refers to a fault alarm or an

event alarm that has not been recovered or acknowledged .

History Alarm: All alarms generated in the system, including

fault alarms and event alarms, when they are recovered or

confirmed are called history alarms.


Querying Alarm by Commands

LST ALMFE

This command is used to query the current alarms (including fault alarms and ev

ent alarms) in the system and returns a maximum of 100 results .

Example:

− LST ALMFE : CNT=100;

LST ALMLOG

This command is used to query history alarms of BSC.

Example:

Query the history alarms of BSC, alarm level: critical and major alarms. Up to 2

00 records will be returned when the alarm level are “Critical” and “Major” f

or history alarm query.

− LST ALMLOG: ALMTP=flt, ALVL=EMERGENCY-1&IMPORTANT-1&CO

MMON-0&NOTIFICATION-0, CNT=200;


Querying Alarm by Commands

LST ALMINF

With this command we can query the detailed information of one alarm with the specific alarm serial No.

Example:

Query the alarm which serial No. is 2200.

− LST ALMINF: CSN=2200;

LST ALMCFG

This command is used to query the configuration information of the alarms which IDs are between start ID and end ID.

Example:

Query the alarms with the IDs between 100 and 200.

− LST ALMCFG: STARTAID=100, ENDAID=200;


Managing Alarm by Commands

RMV ALMFLT

This command is used to recover the specific alarms manually.

Example:

Recover all the alarms which serial No. are between 111 and 222.

− RMV ALMFLT: STARTCSN=111, ENDCSN=222;

RMV ALMLOG

This command is used to delete history alarms generated during the

days you define on LMT.

Example:

Delete all the history alarms between 2005-05-03 and 2005-05-05.

− RMV ALMLOG:SD=2005&05&03,ED=2005&05&05;



SET ALMACK

This command is used to confirm alarms with the serial No. between the

specific range.

Example:

Confirm the alarms with the serial No. between 2000 and 2100.

− SET ALMACK: STARTCSN=2000, ENDCSN=2100;

SET ALMLVL

This command is used to set the alarm levels.

Example:

Set the alarm level as “Major” for alarms which ID is between 100 and 200.

− SET ALMLVL: STARTAID=100, ENDAID=200, NEWALVL=IMPORTANT;



SET ALMMSK

This command is used to shield alarms between the specific ID range you set

on LMT.

Example:

Shield the alarms with IDs between 50 and 80.

− SET ALMMSK: STARTAID=50, ENDAID=80, MSKFLG=MASK;

The system will not store and display the shielded alarms.

SET CLTRPT

This command is used to set alarms not to be reported to the client.

Example:

Set alarm with the ID as 100 not to be reported to the client.

− SET CLTRPT: AID=100, RPTFLG=NONRPT;


Difference Between SET ALMMSK & SET CLTRPT

If SET ALMMSK is executed, the foreground will not stored

corresponding alarms. And the alarms could not be queried by

command “LST ALMLOG” or “LST NEALMLOG”, but the execution

result of “SET CLTPRT” is not in this case.

Maintaining Alarm Box

Check the serial port communication indicator on the alarm box.

Check the status of alarm indicator to see if it conforms to the actual situation.

Check whether the alarm tone can be set correctly.

Check the communication gateway of

the BAM or client used to connect

with alarm box.

Checking Working Status of BAMService

The status should

Checking Communication Status of the BAM and EWS

EWS (Emergency WorkStation) backs up important data such as

BAM database automatically. They take over tasks of the BAM

temporarily in the case of BAM server failure. Therefore, we must

make sure that the BAM communicates with EWS normally.

If the BAM communicates with an EWS normally, we can ping the IP

address of the EWS from the BAM, otherwise, we should check:

Network cable connections between the BAM and local area

network (LAN) Switch

Network cable connections between the emergency workstation

and LAN Switch

Settings of the network adaptor


Checking Auto-Backup Data of the System

To ensure the security of database on the hard disk of BAM server, the system starts a scheduled task after its start-up by executing the command BKP DB automatically to back up BAM database, alarm database, and License files every early morning.

Check whether the following files for the latest three days exist under F:\cdma2000\backup at the BAM and its emergency workstation:

BamYYYYMMDD.dat

AlarmYYYYMMDD.dat

cbsclicenseYYYYMMDD.dat

CSWSYYYYMMDD.dat

BamRegYYYYMMDD.bak

cdma2000YYYYMMDD.ini


Dumping System Data Periodically

To ensure the safety of system data, you should weekly dump

the system backups on the hard disk of BAM server to other

storages so that the system can be recovered immediately in

the case of emergency situation.

You need to dump all files under the directory F:\cdma2000\

backup including database files, registry files, and system

configuration files.

You can select backup modes according to actual situations. It

is suggested to save backups onto hard disks of other

computers on the network.


Purging Useless BAM Data

In routine maintenance of BAM system, we should periodically

purge useless files on the BAM hard disk to release the hard

disk space. In this way, we can store important system data

timely and effectively.

Useless files on the BAM hard disk include:

Programs and data of earlier version backed up before

system upgrade or patching

Files under temporary folders created in daily maintenance


Querying BAM Operation Log
