## Description

For digital trunk links that have a Digital Link Descriptor programmed in the Digital Links form, this alarm indicates a persistent fault on a digital link. Those digital trunk links are included in the system total as output by the Alarm maintenance command.

NOTE: For Italian CAS, the delay period before the alarm is activated (the length of time that an intermittent link fault exists before it becomes a persistent fault and raises an alarm) is specified by entering a value between 0 and 360 seconds in the Digital Link Fault Delay Timer field of the Digital Link Descriptors form.

## Alarm Status

The major threshold is > 0.
