Owner's Manual
1.1 Introduction
Welcome to the world of data communications. You have acquired one of
the finest intelligent data, fax, answering machine and personal voice mail
capable modems available today, model MT5600ZDXV, from Multi-Tech
Systems. This Owner’s Manual will help you install, configure, test and use
your MT5600ZDXV modem.
1.2 Product Description
Your MT5600ZDXV incorporates both V.90 and K56flex modem
technologies,which allows Internet connections at data rates up to 56K bps
over standard telephone lines. The V.90 and K56flex technology is able to
propel data downstream from the Internet to your computer at speeds of up
to56Kbpsbecausedataisdigitallyencodedinsteadofmodulated. 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 MT5600ZDXV 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
forreliable call-progressdetection. Themodem candetectAT&T callingcard
tones. ItisFCC-Registered for connectiontotelephonenetworks without any
Data Access Arrangements (DAA’s).
*Though this modem is capable of 56K bps download performance, line
impairments, public telephone infrastructure and other external technological
factors currently prevent maximum 56K bps connections.
The MT5600ZDXV is a desktop fax/modem for compatible Personal Comput-
ers that also provides support for answering machine and voice mail
capabilities. The MT5600ZDXV provides dial-up asynchronous communica-
tion 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 MT5600ZDXV
through a modular power supply connection included with the modem. All
of these connections are made at the back of the MT5600ZDXV.
The “SPKR or LINE OUT”and “MIC IN”jacks are both located on the side of

the MT5600ZDXV. Hardware installation procedures are described in
Chapter 2.
General features include:
4Compliance with major ITU-T, TIA, and EIA international standards to
ensure compatibility with other modems.
4Distinguishes data, fax, or voice calls using DTMF and tone detection with
software packages supporting these features.
4Caller ID to identify your caller’s phone number (available on U.S.
products).
Data
4SupportstheV.90andK56flexTM standardsfordatatransmissionatspeeds
up to 56Kbps, while maintaining compatibility with lower-speed modems.
Note: the V.90 and K56flex standards transfer data asymmetrically - 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-
speedmodems.
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.
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.
4Automatic disabling of compression when transferring already-com-
pressedfiles.
4Autodial, redial, pulse (rotary) and touch-tone dial.
4Dial tone and busy signal detection for reliable call-progress detection.
4Compatibility with the standard AT command set used by most commu-
nication programs.

Fax
4Supports V.17, Class 1/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.
Voice
4Full-duplex speakerphone support with adjustable speaker volume con-
trol. Can record and play back answering machine messages using
optional microphone and speaker.
4Remote/local telephone answering machine (TAM) capabilities include
voice mail control, record/playback, and call screening.
4Supports AT#V voice commands.

1.3 Software Considerations
You will need data communications (datacomm), fax communications
software and an appropriate application software package to access the
Personal Voice-Mail features of the MT5600ZDXV. You must have Microsoft
Windows 3.1 or later to run these programs. With the appropriate application
software you can use your MT5600ZDXV to:
•speed dial
•mute a phone call
•place a call on hold
•forward or transfer a call
•three-way or conference call
•fax from any Windows’application
