MultMobileUSB User Guide
Introdu tion
Welcome to the world of data communications. You have acquired one of the finest intelligent data and
fax modems available toda from one of Americas oldest and most respected modem manufacturers:
Multi-Tech S stems, Inc. This users guide will help ou install, configure, test and use our modem.
Produ t Des ription
The MT5634MU modem incorporates V.90 technolog , which enables Internet connections at data
rates up to 56 Kbps* over standard telephone lines. V.90 technolog is able to send data downstream
from the Internet to our computer at these speeds because data on the telephone network t picall is
converted from digital to analog onl once before it reaches our modem. Upstream transmissions, and
transmissions between client modems, are limited to data rates of 33.6 Kbps, as are downstream
transmissions that are converted more than once on the telephone network.
Figure 1-1 MT5634MU
The MT5634MU is Plug-and-Pla in Windows 2000, Windows ME, Windows 98, and Windows 95
operating s stems with interactive automatic dialing and command mode configuration. In standard
mode, ou can store up to two command lines or telephone numbers of up to 40 characters each in
the modems nonvolatile memor . The modem pulse- or tone-dials, and recognizes dial tones and bus
signals for reliable call-progress detection. The modem can detect AT&T calling card tones. It also has
Caller ID, remote configuration and incorporates self-resetting lightning protection. The MT5634MU is
FCC-registered for connection without notification to the telephone compan .
The MT5634MU 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.
The MT5634MU operates with Multi-Techs Global Wizard program. Telephone compan technical
requirements differ from countr to countr . In the Global Wizard program, ou simpl specif the
countr in which ou will operate, selecting from a pull-down menu. Global Wizard does the rest,
automaticall setting up the correct operating parameters for our modem to operate in our countr .
Multi-Techs Flash Wizard utilit allows MT5634MU firmware to be updated b the user.
Universal Serial Bus (USB)
Universal Serial Bus (USB), defined b a consortium of industr leaders, permits connection of multiple
low-speed and medium speed computer peripheral devices such as telephones, modems, printers,
ke boards, mice, and scanners; all from a single personal computer port. The specification, based on
an open architecture is quickl becoming a standard feature in new desktop and notebook computers.
* Although K56flex technology is capable of downloads of up to 56 Kbps FCC regulations currently
restrict ISP modems to downloads of 53 Kbps.

Chapter 1 - Introduction and Description
What Can You Do with Your Modem?
Your Multi-Tech MultiMobile MT5634MU is the gatewa to the exciting world of telecommunications.
You can use it to access commercial on-line information services such as America Online, Genie, and
Prodig . These services provide access to databases, enc clopedias, stock reports, news, weather,
and shopping. The 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 arra of topics from A to Z, while vendor forums provide hardware and software support from Multi-
Tech and other manufacturers. Online services also allow ou to upload and download computer
programs, data files, and updated software such as video and printer drivers.
Your modem can also connect ou 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
easil 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 our fax modemwork at home while communicating with the office b modem
or fax.
And of course, ou can use our modem to exchange faxes with an fax machine in the world,
enabling ou to communicate quickl with businesses and organizations that do not have direct
modem communications.
