The system keeps a record of every alarm that it detects. The alarm and error logs are displayed locally on the management terminal. Depending on the alarm’s effect on system operation, an alarm is classified as MAJOR, MINOR, or WARNING. Alarms are also classified as ON-BOARD or OFF-BOARD.
MAJOR alarms identify failures that cause critical degradation of service and require immediate attention. Major alarms can occur on standby components without affecting service, since their active counterparts continue to function.
MINOR alarms identify failures that cause some service degradation but do not render a crucial portion of the system inoperable. The condition requires attention, but typically a minor alarm affects only a few trunks or stations or a single feature.
WARNING alarms identify failures that cause no significant degradation of service or failures of equipment external to the system. These are not reported to the Avaya alarm receiving system or the attendant console.
ON-BOARD problems originate in circuitry on the alarmed media module.
OFF-BOARD problems originate in a process or component external to the media module.
The alarm log is restricted in size. If the log is full, a new entry overwrites the oldest resolved alarm. If there are no resolved alarms, the oldest error that is not alarmed is overwritten. If the full log consists of only active alarms, the new alarm is dropped and not recorded.
