EXT-DEV ADMIN? Y (External
Device Alarm)
NOTE:
Use this Maintenance Object when the
External Device Alarm Admin?
field
on the
change system-parameters customer-options
form is set to (y). You
must have INADS or INIT login permission to administer EXT-DEV Alarm.
Generic 3i 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 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
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
