APR-UA Unit (Analogue Port Ringer)
The Analogue Port adapter with Ringing provides an interface for installing Single Line
Telephones, modems, NEC VoicePoint Conferencing unit, and other compatible
analogue devices. The APR-UA 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 ohm or a complex impedance interface to devices such as a modem or Single
Line Telephone, the second switch (SW1) is permanently set to position 2. The
APR-UA Unit
requires
an AC adapter (ACA-UA Unit). If a CTA-BA Unit or the HFU-UA
Unit and an APR-UA Unit are both installed, only one AC adapter is required.
