1.1Introduction

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.

1.2Features

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.
