Installing And Programming The Off-Premise Extension
Interface On The Digital Communications System
1.0 Introducing The Off-Premise Extension Interface
This publication describes the features, applications, installation, specifications, and operation of the off-premise
extension interface (OPX-X). The OPX-X is a multipurpose accessory with dual circuits that provide the
following features:
•
OFF-PREMISE EXTENSION—This feature adapts most industry-standard telephone devices to the digital
communications system and allows them to be remotely located. The OPX-X will accept both tone (DTMF)
and pulse (rotary) dialing from these devices.
•
TIE-LINE—This feature allows you to connect two systems to each other using single-pair wiring of dedicated
telephone lines.
•
MODEM ADAPTER—This feature allows the flow of switched data between a data source and a data receiver
through the DXP Plus analog station ports.
The OPX-X is a dual off-premise extension (OPX) unit. It is housed in a self-contained metal enclosure that you
can either wall or rack mount. The OPX-X has an internal power supply and ringing generator. Dual, high
quality, low-loss, balanced, telephone transmission circuitry supports two off-premise extensions.
Each off-premise circuit can drive a load with a maximum ringer equivalence number (REN) of two (2) thus
allowing more than one industry-standard telephone connection at each off-premise location if desired.
The OPX-X will support virtually any industry-standard telephone device such as 500 and 2500-type telephones,
cordless telephones, answering machines, and data modems. The OPX-X provides the interfacing capability
required to connect these devices to analog station ports in digital communications system.
