Chapter 1 - Introduction1.1 Introduction
Welcome to the world of data communications. You have acquired one of
the finest intelligent data/fax modems available today, either the model
MT2834BR or MT2834BLR (MT2834), from Multi-Tech Systems. Your
MT2834 modem provides data communication at 33,600-14,400 bps
(*Enhanced V.34/V.32bis), as well as other prevalent datacomm standards.
The MT2834 also includes adaptive protocol enhancing used in typical
Unix® batch file transfers and support for IBM's AS/400 (iSeries)TM and
System3xTM environment. The MT2834BLR provides support for dial back-
up with automatic leased line restoral. This User Guide will help you install,
configure, test and use your MT2834 data/fax modem.
*Note enhancements on V.34 code (33.6K/31.2K) is awaiting formal ITU
approval; the ITU study group 14 has agreed on the technical side of the
proposal, with formal approval expected at the next ITU meeting in
Geneva.
1.2 Features
The MT2834 automatically adjusts to line conditions and the capabilities of
the modem it connects to, resulting in the highest possible speed, the most
accurate error correction, and the most efficient data compression possible
for each connection. The MT2834 is designed for data rates as high as
33,600 bps in full-duplex mode over public telephone lines.
MT2834 features include:
· Support of data rates of 33,600, 31,200, 28,800, 26,400, 24,000, 21,600,
19,200, 16,800, 14,400, 12,000, 9600, 7200, 4800, 2400, 1200, 0-300
bps.
· Automatic fallback to slower speeds in noisy line conditions, and fall-
forward to faster speeds as conditions improve.
· ITU-T V.42 LAP-M and MNP Classes 3 and 4 error correction.
· Data transfer rates up to 115,200 bps with V.42bis 4-to-1 data
compression.
