3.4 APR-U Unit (Analog Port Ringer)
The Analog Port Adapter with Ringing is the interface for installing Single Line
Telephones, modems, NEC VoicePoint/VoicePoint Plus Conferencing unit,
and other compatible analog devices. The APR-U Unit also generates ringing
signals. By providing ring generation, the user can install a personal fax
machine or an answering machine for convenience.
Two user-adjustable switches are provided on the adapter; one allows for 600
Ω
or a complex impedance interface to devices such as a modem or Single
Line Telephone, the second switch (SW1) is set to position 2. When this
Analog Port Ringer adapter is used, an additional Single Line Telephone or a
modem can be connected to a Multiline Terminal.
If a CTA-U, CTU(S)-U, or HFU-U and an APR-U Unit are both installed, only
one AC Adapter is required.
This adapter can be installed on any DTP or DTU Multiline Terminal except
DTP-2DT-1 TEL, DTP-16HC-1 TEL, or cordless terminals.
