MT5634ZBA-USB User Guide
Introduction
Welcome to the world of data communications. You have acquired one of the finest
intelligent data and fax modems available today from one ofAmerica’s oldest and most
respected modem manufacturers: Multi-Tech Systems, Inc. This User Guide will help you
install, configure, test and use your modem as well as provide links to useful Web sites
and other resources.
Product Description
The MT5634ZBA-USB-Mac modem (hereafter MultiModemUSB) incorporates V.90™
technology, which enables Internet connections at data rates up to 53K bps* over
standard telephone lines. V.90 technology is able to send data downstream from the
Internet to your computer at these speeds because data on the telephone network
typically is converted from digital to analog only once before it reaches your modem.
Upstream transmissions, and transmissions between client modems, are limited to data
rates of 33.6K bps, as are downstream transmissions that are converted more than once
on the telephone network.
The MultiModemUSB comes with interactive automatic dialing and command mode
configuration. In standard mode, you can store up to two command lines or 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 detectAT&T calling card tones, and also has Caller ID,
remote configuration and incorporates self-resetting lightning protection. The modem is
FCC-registered for connection without notification to the telephone company.
The MultiModemUSB is a full-duplex intelligent modem with V.42 error correction, V.42bis
data compression, and V.17 (14,400 bps), Class 1 and 2, Group 3 fax capabilities.
Universal Serial Bus (USB)
Universal Serial Bus (USB), defined by a consortium of industry leaders, permits
connection of multiple low-speed and medium speed computer peripheral devices such
as telephones, modems, printers, keyboards, mice, and scanners; all from a single port.
The specification, based on an open architecture is quickly becoming a standard feature
in new desktop and notebook computers. For more details on the Universal Serial Bus,
refer to the USB Public Web Board on the World Wide Web, at:
http://www.usb.org/
* Although V.90 technology is capable of downloads of up to 56K bps, FCC regulations
currently restrict ISP modems to downloads of 53K bps.

What Can You Do with Your Modem?
Your Multi-Tech modem is the gateway to the exciting world of telecommunications.
You can use it to access commercial on-line information services such as CompuServe,
America Online, Genie, and Prodigy. These services provide access to databases,
encyclopedias, stock reports, news, weather, and shopping. They provide electronic mail
(e-mail) links to subscribers of the same and other services. Public message areas
called forums allow subscribers to trade information and opinions on a vast array of
topics fromA to Z, while vendor forums provide hardware and software support from
Multi-Tech and other manufacturers. Online services also allow you to upload and
download computer programs, data files, and updated software such as video and printer
drivers.
Your modem can also connect you to the Internet, an international computer network of
universities, libraries, businesses, and government agencies. Like the commercial online
services, the Internet provides e-mail services, public message areas, and access to
information and software, much of it easily accessed through the World Wide Web.
Other uses include direct links to colleagues with modems, to banks, and to service
bureaus. You can also telecommute with your fax modem—work at home while
communicating with the office by modem or fax.
And of course, you can use your modem to exchange faxes with any fax machine in the
world, enabling you to communicate quickly with businesses and organizations that do
not have direct data communications.

Required Equipment
In addition to the contents of your modem package, you need the following equipment.
Computer
Your modem can only be connected to a computer with a USB port.
Telephone Line
You must have a telephone line with jack (connector) that accepts the cable that comes
with the modem. If you do not have a telephone jack near your computer, you should
install one before proceeding.
Do-it-yourself telephone extension kits and accessories are available wherever
telephones are sold. You may also hire an independent contractor or your local telephone
company to install an extension. If you want a separate line for your fax modem, you
must contact your telephone company.
Communications Software
To operate your modem, you must have data communications and fax communications
software. Data communications software simplifies control of the modem by guiding you
through the process of selecting your serial port, your port speed, and other variables,
and then storing your settings, including frequently called phone numbers, so they can be
recalled with the stroke of a key or the click of a mouse. Data communications software
must be set up (or configured) before you can use it.

MT5634ZBA-USB User Guide
Connections
To use your modem, you must connect it to your computer (“USB”), to a telephone line
(“LINE”), and optionally to a telephone set (“PHONE”).
PHONE LINE
USB
Figure 3-1. USB and communications connectors.
Connecting to the Computer (“USB”)
Using a USB cable, connect the USB connector on the modem to a USB connector on
the back of your computer*.
* Note: Do not plug the modem into the USB port on you keyboard—this port is for low
power devices such as a mouse.
Connecting to the Telephone Line (“LINE”)
Plug one end of the cable provided with the modem into the telephone jack in your home
or office. Plug the other end into the LINE jack on the modem.
Note: The LINE jack is not interchangeable with the PHONE jack. Do not plug the
telephone into the LINE jack or the line cable into the PHONE jack.
Note: The Federal Communications Commission (FCC), Industry Canada, and other
regulatory agencies impose certain restrictions on equipment connected to public
telephone systems. SeeAppendixAfor more information.
Connecting to a Telephone Set (“PHONE”)
If you wish to connect a telephone to the same line as the modem, you can plug it into
the modem’s PHONE jack. This connector is provided as a convenience; you can also
connect your telephone to a duplex jack inserted into your wall jack.
Note: The PHONE jack is not interchangeable with the LINE jack; do not plug the
telephone into the LINE jack or the line cable into the PHONE jack.
Surge Protectors and Lightning
Your modem has self-resetting lightning protection to protect it from electrical spikes on
the telephone line. During an electrical storm, your safest course is to unplug your
computer equipment from both the power outlet and the telephone line.
