The modem location depends on the type of communications system. The
modem is located:
■
on the circuit pack for System 75 and DEFINITY Generic 1.
■
external to the communications system for System 85 and DEFINITY
Generic 2.

Common RPSD Lock Configuration
Connect the RPSD Lock to the administration terminal via the AUX. PORT on the
back of the Lock, and power it from an AC outlet or Uninterruptible Power Supply
(UPS).
On System 85 and DEFINITY Generic 2, the modems are external to the
communications system. Check that the modems are plugged into the UPS,
since a power outage that results in either the RPSD Lock or the modem being
inaccessible also results in the RMATS channel being inaccessible.
