Chapter 1 - Introduction and Description

Introduction

Welcome to the world of data communications. You have acquired

one of the finest intelligent data, fax capable modems available today,

model MT5600ZDX, from Multi-Tech Systems. This Owner’s Manual

will help you install, configure, test and use your MT5600ZDX modem.

Product Description

Your MT5600ZDX incorporates a new modem technology, called

K56flex

, that enables Internet connections at data rates up to 56K

bps over standard telephone lines. K56flex technology is able to

propel data downstream from the Internet to your computer at speeds

of up to 56K bps because data is digitally encoded instead of

modulated. Upstream transmission, mostly keystroke and mouse

commands from your computer to the central site, continue to flow at

the conventional data rate of 33.6K bps.

Your MT5600ZDX offers interactive automatic dialing, as well as

command mode option configuration. You may store four command

line/telephone numbers, of up to 40 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. The

modem can detect AT&T calling card tones. It is FCC-Registered for

connection to telephone networks without any Data Access

Arrangements (DAA’s).

* Although K56flex technology is capable of downloads of up to 56K

bps, FCC regulations currently restrict ISP modems to downloads of

53K bps.

MT5600ZDX Owner's Manual

The MT5600ZDX is a desktop fax/modem for compatible IBM Personal

Computers that also provides support for answering machine and

voice mail capabilities. The MT5600ZDX provides dial-up

asynchronous communication capability with other personal

computers, terminals, on-line computer services or other types of

computer systems. Connection to the phone line and/or an attached

telephone device is made by RJ11 modular type connectors; the PC

connection is made via an RS232C/V.24 serial cable receptacle; and

low voltage DC power is supplied to the MT5600ZDX through a

modular power supply connection included with the modem. All these

connections are located on the rear of the MT5600ZDX. Hardware

installation procedures are described in Chapter 2.

General features include:

• Compliance with major ITU-T, TIA, and EIA international

standards to ensure compatibility with other modems.

• Distinguishes data, fax, or voice calls using DTMF and tone

detection with software packages supporting these features.

• Caller ID to identify your caller’s phone number (available on U.S.

products).

Data

• Supports the K56flexTM standard for data transmission speeds up

to 56Kbps, while maintaining compatibility with lower-speed

modems.

Note the K56flex standard asymmetrically transfers data--client

downloads at speeds up to 56K bps, client uploads at speeds up

to 33.6K bps.

• Supports the enhanced ITU-T V.34 standard, with data

transmission speeds to 33.6K bps, while also maintaining

compatibility with lower-speed modems.

• Supports asynchronous data rates at 56K, 33.6K, 31.2K, 28.8K,

26.4K, 24K, 21.6K, 19.2K, 16.8K, 14.4K, 12K, 9600, 4800, 2400,

1200, and 300 bps.

• Automatic fallback to slower speeds in noisy line conditions, and

fall-forward to faster speeds as conditions improve.

• ITU V.42 LAP-M and MNP Class 3 and 4 error correction.

• ITU V.42bis (4-to-1) and MNP 5 (2-to-1) data compression.

Chapter 1 - Introduction and Description

• Automatic disabling of compression when transferring already-

compressed files.

• Autodial, redial, pulse (rotary) and touch-tone dial.

• Dial tone and busy signal detection for reliable call-progress

detection.

• Compatibility with the standard AT command set used by most

communication programs.

• MNP10 and MNP10ECTM Enhanced Cellular Performance (error

correction).

• H.324 compliant (videophone ready).

• Distinctive ring support to route voice, data, or fax calls on a

single phone line.

• Plug and Play (

PnP

) serial support.

• FlashROM upgradable.

Fax

• Supports V.17, Group 3 fax communication standards, allowing it

to communicate with other fax modems as well as with fax

machines.

• Sends and receives faxes from your computer at 14,400 bps,

9600 bps, 7200 bps, 4800 bps, 2400 bps, or 300 bps.

Chapter 2 - Installation

Installation

In addition to the contents of the MT5600ZDX package, you will need

the following equipment.

Computer

The MT5600ZDX can be connected to any computer with an RS-232

serial port.

Note

your computer system should have a processor

speed of at least 75 MHz in order to take full advantage of the

telephony features of this product.

Serial Cable

You must provide a serial cable to connect the MT5600ZDX to your

computer. Serial cables are available at computer stores and many

office supply stores. The cable must have a DB-25P connector at the

modem end. For IBM and compatible computers, the other end may

have a DB-25P connector or a DB-9S connector, depending on your

particular computer and whether you are using the COM1 or the

COM2 serial port. The FCC requires cables to be shielded.
