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

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
