Chapter 1 – Introduction

Chapter 1 - Introduction

Congratulations on your purchase of the Multi-Tech MT5656ZDX-Series modem.

• The Multi-Tech MT5656ZDX modem is your data/fax modem.

• The MT5656ZDX-V offers your voice option.

You have acquired one of the finest intelligent data/fax or voice/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

The 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 digitial t o analog only one before it reaches your modem. Upstream
transmissions and transmissions be twee n 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-reset ting 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 – Hardware Installation

Overview – Connecting the Modem to Your System

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

MT5656ZDX Connections

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

Plug one end of the RS-232 serial cable into the RS-232 connec tor on the mo de m, and plug th e
other end into a serial port connector on your computer.

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 plu g th e phone into the
LINE jack or the line cable into the PHONE jack.

(Optional) Connect the Modem to the Phone

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

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.

Chapter 2 – Hardware Installation

A Note About Power Connection, Surge Protectors, and Lightning

Power surges and other transient voltages on power lines, such as those caused by lightning
strikes, can damage or destroy your modem. Therefore, we recommend that you plug the modem
into a surge protector rather than directly into a wall outlet, preferably a sur ge pro t ector that provides
protection against electrical spikes on the phone line as well as on the power line. Note that not even
a surge protector can guard against damage f rom a n earby lightn ing strike. Durin g an electrica l
storm, it is safest to unplug your computer equipment from both the power outlet and the phone line.

Power-On Test

Test the modem by turning it on (an on-off switch is located on th e side panel) . When you a pply
power, the modem performs a diagnostic self-test. The PWR indicator lights; and if a terminal program
is running, the TR indicator also lights. If this does not happen, check that the power switch is on,
the power supply is solidly connected, and the AC outlet is live. If these measures do not work see
the Troubleshooting chapter.

Note: The Federal Communications Commission (FCC) and Industry Canada impose certain
restrictions on equipment connected to public phone systems. For more information, see A ppendix
B.
