Congratulationson 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.

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.

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.

It is FCC-registered for connection to telephone networks without notification to the telephone company.
