Dterm Series i/Dterm IP Accessories

Direct Station Selection (DSS) Console

This Console is equipped with 60 programmable line keys (each with a two-color LED). These keys can be programmed as Direct Station keys, Function keys, or Line keys. The DCU-60 Console is available in two colors - Black (BK) and Ivory White (WH).

Analog Port Adapter (APR)

The Analog Port Adapter with Ringing (APR-U) provides an interface for installing single line telephones (SLTs), modems*. 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 through the APR-U. The APR-U also 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 at the workstation and connect them through the Dterm Series instrument for convenience.

*When a modem is installed to the Dterm Series Multi-line terminal with the APR-U, the modem and the Dterm Series Multi-line Terminal (handset, speakerphone, headset) cannot be used simultaneously.

Ancillary Device Adapter (ADA)

The Ancillary Device Adapter (ADA-U) allows for a direct connection from the Dterm Series i/ Dterm IP terminal 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.

Computer Telephony Adapter (CTA)

The Computer Telephony Adapter (CTA) provides Dterm with a connection to desktop PC, allowing users to operate Windows®-based Computer Telephony application such as ClientPhone 32.

IP Adapter (IPW)

The IP Adapter Unit (IPW) provides two 10/100 Base-T Ethernet ports to the Local Area Network (LAN) and a built-in switching hub for a PC connection to the adapter itself.

Operating power can be fed by either an AC/DC adapter unit or a power patch panel connected to the LAN switch/hub.

When the IPW is attached to the Dterm, other optional accessories cannot be attached except for Ancillary Device Adapter (ADA).

Wall Mount Unit (WMU)
