DATA OVERVIEW

Data Communications

The system provides up to 24 data device interfaces for data communications. Using data devices allows a
network to share a limited number of business resources such as modems, printers, and PC's. The system's
data devices can switch asynchronous RS-232-C data at speeds from 300 to 19.2K.
In addition to the CPU's serial port connection and the ENTU-S's ethernet connection, there are four types of
data devices available: APA, APR, CTA and CTU.

APA Adapter

The APA Adapter provides an analog interface for the keyset. The APA Adapter does not provide ringing, so
the connected device is used for outgoing calls only (for example, when using a modem). One keyset can
have either an APA or an APR Adapter. Both adapters cannot be installed on the same keyset as only one
voice path is provided by the keyset for the adapters. The maximum distance between the APA Adapter and
the analog terminal is 49'.
The APA Adapter does not support reverse-polarity, message waiting lamping, or Caller ID.

APR Adapter

The APR Adapter provides an analog interface for the keyset. The APR Adapter provides ringing which
allows the connected device to be used for incoming and outgoing calls. One keyset can have either an APA
or an APR Adapter. Both adapters cannot be installed on the same keyset as only one voice path is provided
by the keyset for the adapters. When installing the APR Adapter, an AC-2R AC/DC adapter (P/N 780135) is
required for power. The maximum distance between the APR Adapter and the analog terminal is 49'.
The APR Adapter does not support reverse-polarity, message waiting lamping, or Caller ID.
When installing the APR adapter, there must be an extension port available for the adapter or it will function
like an APA adapter (only one physical port assigned to the phone so only one phone can be used at a time).
