EXT-DEV ADMIN? Y (External Device
Alarm)
NOTE:
Use this Maintenance Object when the External Device Alarm Admin? field
on the System-parameters Customer-options form is set to (y). You must
have INADS or INIT login permission to administer EXT-DEV Alarm.
Maintenance circuit packs each have alarm leads which can be connected to
external devices such as Uninterruptible Power Supplies (UPS) or adjuncts such
as AUDIX. Certain conditions on the external device close the contacts on the
alarm leads to notify the switch which in turn originates an EXT-DEV alarm.
The special locations UUmajor and UUminor are used to designate the major or
minor maintenance board alarm connection for cabinet UU. The major/minor
designation specifies the port, not the alarm level associated with the connection;
for example, the “major” port can be administered as a major, minor, or warning
alarm, and the “minor” port can be administered as a major, minor or warning
alarm. In addition Analog line ports can also be administered as external device
alarms.
NOTE:
An unadministered maintenance board external device alarm port, that is
sensing a contact closure will have an entry in the Error Log and in the
Alarm Log. INADS will not receive warning alarms.
In the Standard Reliability PPN the Maintenance Processor (TN786B or
TN2404/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 the status to the Maintenance processor
(TN786B or TN2404/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,
555-204-111, for more details.
