Alarm Types

The alarms in the BSC6800 system can be divided into fault alarms and

event alarms:

>Fault alarms triggered by hardware fault or abnormity of major functions

Fault alarms can be divided into active or recovery alarms

>Event alarms indicate some occasional events generated during the

running of the equipments

Event alarms represent an instantaneous state of the system that

may not be a fault

Event alarms cannot be divided into active or recovery alarms

>Fault alarms have higher severity than event alarms


6/31


Alarm Severity

The BSC6800 has 4 alarm severity levels (listed in a descending order):

>Critical alarm

Reporting faults that affect the services, and need treatment immediately

>Major alarm

Reporting faults that affect the QoS, and need treatment in time

>Minor alarm

Reporting faults that are not serious enough to affect the QoS, but need

treatment at proper time

>Warning alarm

Reporting faults that potentially threaten the system services, and need

treatment according to specific situations

Event Types

According to specific faults, alarm events can also be divided into 10 types:According to specific faults, alarm events can also be divided into 10 types:

Event Types Correlative Alarms

Power system Alarms related to the power system

Environment system Alarms related to the equipment room environment, such as temperature,humidity, and access control

Signaling system Alarms related to the signaling system

Trunk system Alarms related to the trunk system, including trunk circuits and trunk boards

Hardware system Alarms related to a board, such as clock and CPU

Software system Alarms related to software

Running system Alarms generated during the running of the systemCommunication system Alarm related to the communication system, such as the one between hosts

and BAM servers

QoS Alarm related to QoS

levels: NOMASK, LOW, MEDIUM and HIGH

>HIGH: mask most of the derived alarms

>MEDIUM: mask alarms not as many as HIGH, but more

than LOW

> LOW: mask only high-correlation derived alarms

>NOMASK: the mask function is not in use

Fault Testing Function

The function of system fault testing is to collect

correlative fault information for locating and

clearing alarms

The BSC6800 provides the following fault tests:

>Load Control Test

>E1 Test

>AAL2 PATH Test

>SAAL Test>Other Tests
