Alarm levels
If a maintenance object in the system begins to fail some of the periodic tests, the system
automatically generates an alarm that indicates the system needs to be restored to a normal
condition. The system identifies three levels of alarms:
● Major alarms — Failures that cause critical degradation of service and require immediate
attention.
● Minor alarms — Failures that cause some degradation of service, but do not render a
crucial portion of the system inoperable. This condition requires action, but its
consequences are not immediate. Problems might be impairing service to a few trunks or
stations or interfering with one feature across the entire system.
● Warning alarms — Failures that cause no significant degradation of service or failures in
equipment external to the system.
