Introduction

GENERAL

The UDS V.3229 and the V.3229L are versatile high

speed asynchronous or synchronous modems that

allow data transfer between two host computers via

the telephone communication system.

The modems can operate full-duplex on both dial-up

and leased lines. The modems are compatible with

all required standards and recommendations, and

feature a wide variety of automatic, remote, and

backup capabilities.

Major characteristics include:

¥14.4 kbps data rate

¥V.42 bis and MNP 5 error control protocols with

data compression

¥a V.25 bis autodialer

¥secure operation

¥trellis coding for superior signal-to-noise perfor-

mance.

Data Rates

The V.3229 operates at data rates of

¥7.2, 12.0, and 14.4 kbps trellis-coded per CCITT

V.32 bis

¥9.6 kbps trellis-coded and 4.8 and 9.6 kbps uncoded

per CCITT V.32 bis

¥2400 and 1200 bps per CCITT V.22 bis

¥300 bps per Bell specification 103
