Handling E1/T1 Alarms

Alarms are reported by the LEDs on the X330W-2DS1 and via the CLI. When an alarm condition is detected by X330W-2DS1, it sends a signal to all E1/T1 devices connected to it. Alarms can be categorized as one of the following:

•Local Alarm Indication - Generated by the X330W-2DS1 as a result of a line status problem sensed by the X330W-2DS1.

•Remote Alarm Request - Received by the X330W-2DS1 from the remote module.

The following table provides a list of alarms, the type of alarm, and the alarm condition on the module from which the alarm originates.
