Congratulations on your purchase of the MultiModemII modem. You have acquired one of the finest intelligent data/fax modems available today from one of the world’s oldest modem manufacturers: Multi- Tech Systems, Inc. This user guide will help you install, configure, test and use your modem.

Product Description

This modem supports two-wire and/or four-wire leased lines. The four-wire leased line includes the dial backup and automatic leased line restoration features. Please note that, because leased-line operation consists of two client modems connected to each other, the maximum leased line data rate is 33.6K bps.

The MT5600BA-V.92 modem supports both two-wire and four-wire leased lines. The MT5600BA modem supports a two-wire leased line.

The MT5600BL modem supports a four-wire leased line.

The MultiModemII offers interactive automatic dialing. You can store four command lines or telephone numbers of up to 30 characters each in the modem’s nonvolatile memory. The modem pulse- or tone- dials, and recognizes dial tones and busy signals for reliable call-progress detection. It can also detect AT&T calling card tones. It is FCC-registered for connection to telephone networks without notification to the telephone company.

The MultiModemII front panel includes a liquid crystal display and four buttons, which together can be used to either display the current connection status of the modem or to configure the modem. The MultiModemII also can be configured through standard AT commands.
