FIGURE 2-4
Common RPSD Lock Configuration
The Lock is installed between the CO line and the PBX modem. The modem location depends
on the type of PBX. The modem is located:
■
on the circuit pack for System 75 and DEFINITY Generic 1
■
external to the PBX for System 85 and DEFINITY Generic 2
The RPSD Lock must also be connected to the administration terminal via the Aux. Port on the
back of the RPSD Lock and powered from an AC outlet or Uninterruptible Power Supply (UPS).
On System 85 and DEFINITY Generic 2, the modems are external to the PBX. The modems
should also be plugged in to the UPS since a power outage which results in either the RPSD Lock
or the modem being inaccessible will result in the RMATS channel being inaccessible.
