l The alarms can be classified into three types:

p Fault alarm : A fault alarm corresponds to a fault. It can be a circuit fault, signaling unreachable, link interruption, or board failure. It is displayed as a fault in the alarm report. When a fault is recovered, a recovery alarm will be generated accordingly.

p Event alarm : An event alarm describes an occasional and instant event during

system operation. It has no corresponding recovery alarm. Some event alarms recur regularly. It can be a call connection or board loading.

p Recovery alarm : Each recovery alarm has a corresponding fault alarm. It can be regarded as a part of the fault alarm.

l There are four levels of alarms, classified by severity. Each identifies a different level of impact on service.

p Critical : Critical alarms have already affected the quality of service, and require immediate actions even in non-duty hours. The equipment and network resource

might be completely unavailable.

p Major : Major alarms have already affected the quality of service, and require immediate actions. The quality of service and the service provisioning capability of the equipment are degraded, and must be restored during your duty hours.

p Minor : Minor alarms have not affected the quality of service, but require treatment in proper time or further observation to prevent graver faults and errors.

p Warning : Warning alarms indicate potential errors that might affect the service.
