Clear Alarm
The Clear Alarm (C A) command set will clear all activity initiated by an
alarm: the external alarm hardware will be deactivated (the contact normally
open will be reopened), the LED light will go out, an entry will be made in
the alarm log of the date and time the alarm was cleared, and line processing
will cease (for alarm level 2 only). When this command set is typed in, the
MMI will display the message "Alarm acknowledged." If the alarm condition
still exists, the alarm will be declared again.
Display Alarms
A detailed report of the most recent 100 alarms with time and date stamps can
be displayed by entering the Display Alarms (D A) command set into the
MMI. Entering the Display Alarms (D A) command set will cause a screen
similar to the following to appear:
