236 NT5D11 and NT5D14 Lineside T1 Interface cards
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 turns on. In this mode, no yellow alarms
are sent and the Lineside T1 card does not enter line processing mode.
Alarm messages are still sent to the MMI terminal and the LED light
continues to indicate alarm conditions.
Alarm Enable
The Alarm Enable (A E) command set does the opposite of the Alarm
Disable command set. It enables the external alarm contacts. When this
command set is typed in, the MMI displays the message "Alarms Enabled."
In this mode, yellow alarms can be sent and the Lineside T1 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:
Alarm Log
3/03/95 1:48 Yellow alarm on T1 carrier
3/03/95 1:50 Initialized Memory
3/03/95 2:33 T1 carrier level 1 alarm
3/03/95 3:47 T1 carrier level 2 alarm
3/03/95 4:43 T1 carrier performance within thresholds
3/03/95 15:01 Log Cleared
The Pause command can be used to display a full screen at a time by
entering D A P.
Clear Alarm Log
Clear all entries in the alarm log by typing in the Clear Alarm Log (C A L)
command set.
