DATA OVERVIEW
Data Communications
The system provides up to 192 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.
There are four types of data devices available: APA, APR, CTA and CTU.
APA Adapter
The APA Adapter provides an analogue interface for the system phone. The APA Adapter does not
provide ringing, so the connected device is used for outgoing calls only (for example, when using a
modem). One system phone can have either an APA or an APR adapter. Both adapters cannot be
installed on the same system phone as only one voice path is provided by the system phone for the
adapters. The maximum distance between the APA Adapter and the analogue terminal is 15 metres.
The APA Adapter does not support reverse-polarity, message waiting lamping, or Caller ID.
APR Adapter
The APR Adapter provides an analogue interface for the system phone. The APR Adapter provides
ringing which allows the connected device to be used for incoming and outgoing calls. One system
phone can have either an APA or an APR adapter. Both adapters cannot be installed on the same sys-
tem phone as only one voice path is provided by the system phone for the adapters. When installing the
APR adapter, an AC/DC adapter is required for power. The maximum distance between the APR
Adapter and the analogue terminal is 15 metres.
The APR Adapter does not support reverse-polarity, message waiting lamping, or Caller ID.
