Defining alarm conditions
Alarm conditions are designed to alert you to conditions that can
negatively affect service on the T1 line. From a functional point of view,
alarm conditions actually include alarms, performance alerts, and events.
■
Alarms imply that something is out-of-service or broken.
■
Performance alerts indicate that line service is degraded. Usually, a
user-specified threshold has been exceeded.
■
Events include loopbacks. An alarm condition from setting a
loopback lets you know, preventatively, that you are putting part of
the line out of service.

conditions which solicit alarms.
To define alarm conditions, follow these steps:
1.
Set the EQP BER (Bit Error Rate) threshold and the NET BER
threshold
