Chapter 1 - Introduction and Description
Introduction
Welcome to the world of data communications. You have acquired one of the
finest intelligent modems available today, the MultiModem ZDX, from Multi-Tech
Systems. This Owner's Manual will help you install your MT5600ZDX data/fax or
MultiModemZDX data/fax/voicemodem.
Product Description
Your MultiModemZDX incorporates both V.90 and 56K modem technologies,
allowing Internet connections at data rates up to 56K bps over standard telephone
lines. The V.90 and 56K technology can propel data downstream from the Internet
to your computer at speeds 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 MultiModemZDX 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 MultiModemZDX is a desktop fax/modem for compatible Personal Computers.
The MT5600ZDXV model also provides support for answering machine and voice
mail capabilities. The MultiModemZDX 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 MultiModemZDX through
a modular power supply connection included with the modem. All of these
connections are made at the back of the MultiModemZDX.
The "SPKR or LINE OUT" and "MIC IN" jacks are both located on the side of the
MultiModemZDXV.
Hardware installation procedures are described in Chapter 2.
* 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.
