Clear Alarm

The

Clear Alarm (C A)

command clears all activity initiated by an

alarm: the external alarm hardware is deactivated (the contact normally
open is reopened), the LED goes out, an entry is made in the alarm log
of the date and time the alarm was cleared, and line processing ceases
(for alarm level 2 only). When this command is typed, MMI displays the
message Alarm acknowledged. If the alarm condition still exists, an 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 into

the MMI, which causes a screen similar to

Figure 72 "Display Alarm (D A)

screen" (page 308)

to appear.
