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.

More detailed information about alarms can be obtained using the

show controllers

CLI command. For more information, refer to "Monitoring

Traffic" on page 79.
The following sections discuss the different types of alarms, how each alarm type is
indicated, and possible corrective actions to end the alarm.
