Alarm Disable
The Alarm Disable (A D) command disables the external alarm contacts. When this
command is typed, the MMI displays the message Alarms Disabled and the MAINT LED lights.
In this mode, no yellow alarms are sent and the LEI does not enter line processing mode. Alarm
messages are sent on the MMI terminal and the LED continues to indicate alarm conditions.
Alarm Enable
The Alarm Enable (A E) command does the reverse of the Alarm Disable (A D)
command. It enables the external alarm contacts. When this command is typed in, the MMI
displays the message Alarms Enabled. In this mode, yellow alarms can be sent and the LEI
can enter line processing mode.
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 59: Display Alarm (D A) screen
Figure 59: Display Alarm (D A) screen
The Pause command can be used to display a full screen at a time, by entering D A P. If there
is more than one screen in the log, the MMI scrolls the log until the screen is full, then stops.
When ready to see the next screen, press any key. The display shows another screen and
stops again. This continues until the entire log is displayed.
