Introduction

Welcome to the world of data communications. You have acquired one of

the finest intelligent data/fax modems available today, the MultiModem

ZDX or ZDXV, from Multi-Tech Systems. This Owners Manual will help you

install, configure, test and use your modem.

Product Description

Your modem incorporates new modem technologies called V.90 and

K56flexTM, that enable Internet connections at data rates up to 56K bps over

standard telephone lines. This 56K 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 transmis-

sion, 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 modem 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 this modem is capable of 56K bps download performance, limitations

caused by line impairments, public telephone infrastructure, and other external

technological factors currently prevent maximum 56K bps connections.

This is a desktop fax/modem for compatible IBM Personal Computers; and

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 modem through a modular power supply connection shipped with it.

All these connections are located on the rear of the modem. Hardware

installation procedures are described in Chapter 2.

User Guide

General features include:

4Compliance with major ITU-T, TIA, and EIA international standards to

ensure compatibility with other modems.

4Distinguishes data, and fax calls. The MT5600ZDXV also distinguishes

voice calls using DTMF and tone detection with software packages that

support these features.

4Caller ID to identify your callers phone number (available on U.S.

products).

Data

4Supports V.90 and K56flexTM for data transmission speeds up to 56Kbps,

while maintaining compatibility with lower-speed modems.

Note the V.90 and K56flex standards asymmetrically transfers data--

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

to 33.6K bps.

4Supports the enhanced ITU-T V.34 standard, with data transmission

speeds to 33.6K bps, while also maintaining compatibility with lower-

speed modems.

4Supports V.90 and K56flex speeds plus 33.6K, 31.2K, 28.8K, 26.4K,

24K, 21.6K, 19.2K, 16.8K, 14.4K, 12K, 9.6K, 7.2K, 4.8K, 2.4K, 1.2K,

and 0-300 bps.

4Automatic fallback to slower speeds in noisy line conditions, and fall-

forward to faster speeds as conditions improve (line quality monitoring).

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

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

4MNP10 and MNP10ECTM Enhanced Cellular Performance (error correc-

tion).

4H.324 compliant (videophone ready).

4Automatic disabling of compression when transferring already-com-

pressed files.

4Autodial, redial, pulse (rotary) and touch-tone dial.

4Dial tone and busy signal detection for reliable call-progress detection.

4Distinctive ring support to route voice, data, or fax calls on a single

phone line.

4Plug and Play (PnP) serial support.

4FlashROM upgradable.

4Compatibility with the standard AT command set used by most commu-

nication programs.

Fax

4Supports V.17, Class 1 and Class 2 Group 3 fax communication standards,

allowing it to communicate with other fax modems as well as with fax

machines.

4Sends and receives faxes from your computer at 14,400 bps, 9600 bps,

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