Clear Alarm
The Clear Alarm (C A) command set clears all activity initiated by an alarm:
the external alarm hardware is deactivated (the contact normally open is
reopened), the LED light goes out, an entry is made in the alarm log of the
date and time when the alarm is cleared, and line processing ceases (for
alarm level 2 only). When this command set is typed in, the MMIl displays
the message "Alarm acknowledged." If the alarm condition still exists, the
alarm is 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 causes a screen
similar to the following to appear:

set causes a screen similar to the following to appear:
