Alarm)
NOTE:
Use this Maintenance Object when the External Device Alarm Admin? field
on the
change system-parameters customer-options form is set to (n).
In the Standard Reliability PPN the Maintenance Processor (TN786B or TN790) in
carrier (A) monitors the EXT-DEV alarm leads. In the High or Critical PPN, the
Duplication Interface (TN772) circuit pack in carrier (A) monitors the EXT-DEV
alarm leads, and provides status to the Maintenance processor (TN786B or
TN790) in the active SPE. In the EPN the Maintenance Board (TN775) monitors
the EXT-DEV alarm leads. The system only recognizes pairs connected to the 1M
and 1m (ALARM MONITOR) leads. Pairs connected to the 2M, 2m, 3M, 3m, and
3w are not recognized by the system. Refer to the
DEFINITY Communications
System Generic 1 and Generic 3i Wiring,
