Alarm Classification

According to the generation time, alarms are classified into: Active alarm: An active alarm is a fault alarm not recovered in

the BSC6000 system

History alarm: A history alarm is an alarm generated in the

BSC6000 system

History alarms consist of the following:

Fault alarms recovered

Fault alarms not recovered

Event alarms


7/36


Alarm Classification

According to the alarm nature, alarms are classified into:

Fault alarm: A fault alarm is an alarm that is reported to the

network management equipment when equipment has faults or

exceptions. After the faults or exceptions are processed and

cleared, the alarm is cleared

Event alarm: An event alarm is a alarm generated to indicate a

transient state during equipment operation. Some event alarms

are generated periodically. Event alarms are only to notify that

the system is in alarm state and thus do not require handling


8/36


Basic Concepts of Alarms

Alarm serial number: The alarm serial number is arranged

on the basis of alarm raised time. The alarm serial

number is the only index in the alarm logs. The alarm

generated and the alarm cleared use the same alarmserial number

Alarm name: The alarm name has a one-to-one mapping

with the alarm ID


9/36


Basic Concepts of Alarms

Alarm raised time

Recovery time

Alarm ID: An alarm ID defines a type of alarms and

represents a specific type of faults or events. Alarm ID

is the only index of alarm item, and is the main

keyword of the alarm configuration table in the network

management system

Basic Concepts

Alarmseverity

Definition Handling method

Critical Alarms that affect the services provided by thesystem

Critical alarms must be handled immediately evenif they are generated outside working hours. If the

equipment or resources are totally unavailable, theequipment or resources have to be recovered.

Handle the alarms immediately.

Otherwise, the system may be unavailable.

Major Alarms that affect the quality of service

Major alarms must be handled during workinghours. If the quality of services provided by certainequipment or resources decreases, the equipmentor resources need to be recovered.

Handle the alarms in time.

Otherwise, some major functions may be affected.

Minor Alarms that do not affect the quality of services butmay lead to more serious faults

Minor alarms need handling in proper time orfurther check.

Check the alarm causes and

eliminate them.

Warning Alarms indicating that there may be faults affectingthe quality of services

Learn the running status ofthe system

Alarm severity: Critical Alarm, Major Alarm, Minor Alarm, Warning Alarm

Basic Concepts

Classification of network management: The network managementis divided into power system, environment system, signaling system,

trunk system, hardware system, software system, operating system,

communication system, quality of services, processing faults, and so

on

Location information:Location information is the information used to locate

alarms. The location information in the alarm recovery report is the same as that

in the corresponding fault alarm report

Alarm type: Fault alarm or event alarm

Alarm Clear Flag: The sign indicates whether an alarm is cleared.

The Flag is either not cleared or cleared

Shield Flag: The Shield Flag shields the alarm information not required


12/36


Basic Concepts

To Alarm Box Flag: To Alarm Box Flag controls the alarm

reporting to the alarm box

Synchronization Serial Number: The synchronization serial

number is arranged on the basis of the sending time of thealarm report. The synchronization serial number ranges

from one to 0x7ffffffe (hexadecimal) in a cyclical order


13/36


Connection of Alarm Box Connection scheme: Through the serial port, the alarm box is

connected to the LMT client

When an alarm is reported, LMT uses the Convert program to drive

the alarm box to generate an audible and visual alarm

The operator uses the LMT alarm console to control the alarm box,

for example, stopping the alarm sound and the alarm indictor

Channel to Report Alarms of Local Subrack

Process of reporting alarms of the local subrack:

SMU generates alarms

After being screened and filtered on SMU, alarms are switched through GE and

reported to GBAM

GBAM reports alarms to LMT/EMS and records the alarm log

The Convert module of LMT drives and output the alarm box

Channel to Report Alarms of Remote Subrack

Process of reporting alarms of remote subrack: The remote subrack SMU generates alarms

Alarms are screened and filtered on SMU

Alarms are switched through GE to the GEIUT of the local subrack, and then

sent through SS7 link of the Ater interface to the GEIUT board of the central

subrack

The GEIUT board of the local subrack switches alarms through GE and

reports to GBAM

GBAM finishes corresponding output (send the output to LMT/EMS and

records the alarm log)

Channel to Report BTS Alarms Process of reporting BTS alarms:

Alarms generated at BTS are screened and filtered inside the BTS

Alarms are sent through OML links and sent to EIUB of the local subrack.

Alarms are processed through LAPD protocol on the EIUB, switched

through GE, and sent to GBAM

GBAM finishes the alarm output (reports alarms to LMT/EMS and recordsthe alarm log)
