Chapter 2: Introduction
2.5 Features of the ISDN TA/V
Your ISDN TA/V is a fully featured, high-speed digital dial-up device which
provides reliable asynchronous and synchronous operation over the ISDN. As
a complement to the high speed data transfer of up to 64000 bps, ITU V.42bis
data compression and ITU V.42 error correction are supported. The data
transfer speed between the DTE interface and your attached computer can
be configured to be as high as 115200 bps.
The ISDN TA/V’s compatibility with a number of dialing methods and
protocols, such as asynchronous AT commands and ITU V.25bis dialing,
allows you to use the unit in a variety of applications and environments, and
to control the ISDN TA/V’s configuration, dialing characteristics and
diagnostic features.
Four factory set configurations, containing the most commonly-used DTE
interface settings, are permanently stored in the Terminal Adaptor’s memory,
providing you with a quick and easy method of configuring the unit to be
compatible with asynchronous and synchronous data environments,
conforming to ITU V.24/V.28, X.21 (V.11) or V.36.
The principal features are:
• Support for digital to digital communication at speeds up to 64000 bps.
• V42bis data compression and V42 error correction via the ISDN sevice.
• V.110 rate adaption techniques.
• Rear-panel phone socket for connecting a PSTN telephone handset
(or other analogue equipment) to the ISDN service.
• Simultaneous support for ISDN-to-ISDN voice and data calls.
• All available DTE and analogue ports have access to either or both ISDN B
channels.
• Asynchronous dial DTE data rates from 300 to 115200 bps.
• Asynchronous AT commands entered via the DTE interface or the
dedicated CONTROL port.
• ISDN TA/V configuration changes via AT commands and the Intro
software program.
