card can enter line processing mode.
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 clears, and line processing
ceases (for alarm level 2 only). When this command set is typed in, the MMI 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:
