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.
Alarms are communicated to the system users and technicians by entries in the
alarm log and the lighting of LEDs located on the attendant console, on all circuit
packs, on the server, on the Cajun Ethernet switch if there is one, and, optionally,
on customer-designated voice terminals. Warning alarms are not reported to the
attendant console.
