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

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


Alarm Classification

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


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

alarm serial number

Alarm name: The alarm name

has a one-to-one mapping

with the alarm ID


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

Alarm severity

Definition Handling method

Critical Alarms that affect the services provided by the system

Critical alarms must be handled immediately even if they are generated outside working hours. If the equipment or resources are totally unavailable, the equipment 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 working hours. If the quality of services provided by certain equipment or resources decreases, the equipment or 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 but may lead to more serious faults

Minor alarms need handling in proper time or further check.

Check the alarm causes and

eliminate them.

Warning Alarms indicating that there may be

faults affecting the quality of services

Learn the running status of the

system


Basic Concepts Classification of network management: The network management

is 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


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 the

alarm report. The synchronization serial number ranges

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

Basic Concepts


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)

The Covert module of LMT finishes driving and output of the alarm box

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 records the alarm log)
