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 Critical

Definition 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.

Handling method 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

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 the alarm report. The synchronization serial number ranges from one to 0x7ffffffe (hexadecimal) in a cyclical order

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 GMPS Service board GSCU GBAM LMT Convert 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 boxGTCS Service board GEIUT GMPS GEIUT GSCU GBAM LMT Convert 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) > The Convert module of LMT finishes driving and output of the alarm boxGMPS BTS GEIUB GSCU GBAM LMT Convert Alarm box
