Ancillary Device Adapter (ADA-U)
The Ancillary Device Adapter (ADA-U) allows for a direct connection to a tape
recorder for logging/recording telephone calls. A dedicated set of input
connectors is also provided for a recording tone unit to inform the parties that
the call is being recorded. The ADA-U does not require an AC adapter.
External Handsfree Unit (HFU-U)
The External Handsfree Unit (HFU-U) provides a solution for small office
teleconferencing by improving the sound quality of speakerphone calls via an
external microphone. This unit is ideal for a working environment where
handsfree calling is a necessity. In order to provide maximum performance,
two user-adjustable switches are provided which allow the speakerphone to be
configured for a unique environment (quiet room, noisy business environment,
and room with acoustic echo). Furthermore, a push-to-mute button is featured
on the external microphone to add privacy for handsfree calling.
Analog Port Adapter with Ringing (APR-U)
The Analog Port Adapter with Ringing (APR-U) provides an interface for
installing single line
VoicePoint/VoicePoint + conferencing unit. By installing the APR-U, calls may
be initiated via a PC modem and switched to voice operation if desired. Data
calls at a maximum speed of 28.8 kbps are also supported with the APR-U.
The APR-U has the added benefit of detecting incoming ringing signals. By
providing ring detection, the user may wish to install a personal fax machine or
an answering machine for convenience. Finally, two user-adjustable switches
are provided on the adapter: one allows for either a 600
impedance interface to a (modem, SLT, etc.), also a second voice channel to
permit calls from the Multiline Terminal and devices installed to the APR-U
simultaneously*. The APR-U requires an AC adapter.
Note 1*: When a modem is installed to the Multiline Terminal with the APR-U,
the modem and the Multiline Terminal (handset, speakerphone, headset)
cannot be used simultaneously.
Note 2*: Dual voice channel capability is available and special programming
may be required from the NEC PBX/KTS systems to support two simultaneous
voice channels.

multilane terminal to a PC. Each CTA-U unit is shipped with multiline Phone
