Chapter 1 – Product Overview

Overview

Multi-Tech MT5656ZDX and MT5656ZDX-V modems are compatible with the ITU-TV.92 protocol that provide
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. The V.92 protocol is able to send
downstream from the Internet to your computer at these speeds because data on the telephone network
typically is converted from digital to analog only once before it reaches your modem. Upstream transmissions and
transmissions between client modems are limited to 33.6K bps, as are upstream transmissions that are converted
more than once on the telephone lines.

Modem features include Plug and Play operation. In standard mode, the modem can store up to four command
lines or telephone numbers of up to 40 characters each in nonvolatile memory. Other modem capabilities include
modem-on-hold, AT&T calling card tone detection, pulse and tone dialing, adaptive answer, V.42bis and V.44 data
compression, and self-resetting lightning protection.

Please note that some V.92 features are turned off in the factory default configuration, and may need to be
turned on, depending on your needs.

Chapter 2 - Installation

Installing on a Windows Computer

Connecting the Modem to Your System

Turn off your computer. Place the modem in a convenient location, then connect it to your computer’s serial port,
to the phone line, to AC power, and to your phone (phone is optional).

1. Connect the Modem to Your PC (RS-232 Connection).

Plug one end of the RS-232 serial cable into the RS-232 connector on the modem, and plug the other end into
a serial port connector on your computer.

2. Connect the Modem to the Telephone Line (Line Connection)

Plug one end of the phone cable into the modem’s LINE jack and the other end into a phone wall jack. The

phone cable is included with your modem.

Note: The LINE jack is not interchangeable with the PHONE jack. Do not plug the phone into the LINE jack

or the line cable into the PHONE jack.

3. (Optional) Connect the Modem to the Phone.

For voice-only calls, plug a phone into the modem’s PHONE jack.

4. Connect the Power

Make sure the power switch is set to OFF. The power switch is located on the side panel of the modem.

Plug the power supply into a power outlet or power strip. Plug the other end into the PWR jack on the
modem.

CAUTION: Use only the power supply cable supplied with the modem. Use of any other power supply voids

the warranty and can damage the modem.
