Chapter 1 - Introduction
Congratulations on your purchase of the MultiModem® II intelligent data/fax modem, model MT5600BR-V92.
You have acquired one of the finest internal data/fax modems available today from one of the world’s
oldest modem manufacturers: Multi-Tech Systems, Inc. This User Guide will help you to install, configure,
test, and use your modem.
Product Description
The MT5600BR-V92 incorporates ITU-T V.92 protocol which provides quick connections, downstream
transmissions at speeds up to 56K bps*, and upstream transmissions at speeds up to 48K bps when
connected to V.92-compatible Internet service providers. Transmissions between the MT5600BR-V92 and
other client modems are limited to 33.6K bps, as are upstream transmissions to non-V.92-compatible
ISPs and downstream transmissions that are converted more than once on the telephone network.
Fax Communications: Supports Class 1, 1.0, and Class 2 faxing at 14.4K bps.
Features: Modem features include automatic fallback to slower speeds in noisy line conditions, and fall
forward to faster speeds as conditions improve. Can autodial, redial, pulse (rotary) and touch-tone dial.
Detects dial tones and busy signals for reliable call-progress detection. Compatible with the standard AT
command set used by most communication programs.
NOTE:
* Though this modem is capable of 56K bps download performance, line impairments, public telephone
infrastructure, and other external technological factors currently prevent maximum 56K bps connections.
