11.4 APR-L UNIT
The APR-L UNIT (Analog Port Ringer) provides an analog interface for the
terminal. The APR-L UNIT adapter provides ringing which allows the connected
device to be used for incoming and outgoing calls. This adapter also provides a
separate extension number for the analog device, which allows both devices to be
used at the same time (this can be removed in system programming if you wish).
One terminal can have an APR-L UNIT adapter.
The maximum distance between the APR-L UNIT and the analog terminal is 49
feet.
With the APR-L UNIT adapter installed, and the analog device attached to the
adapter is in use, the telephone cannot be used – Only one physical port number
is assigned to the telephone. If both the analog device and telephone are picked
up at the same time, the analog device takes priority. If the terminal user is on a
call and the single line telephone is picked up, the single line telephone takes the
call from the terminal user.
The APR-L UNIT does not support reverse-polarity, message waiting, or
Caller ID.

IMPORTANT
When installing or removing the adapters, the telephone should be
unplugged from the system.
