Introduction
Welcome to the world of data communications. You have acquired one
of the finest intelligent data and fax modems available today from one
of America’s oldest and most respected modem manufacturers: Multi-
Tech Systems, Inc. This owner’s manual will help you install, configure,
test and use your modem.
Product Description
The MT5634ZBA and MT5634ZBAV modems incorporate K56flex ™
technology, which enables Internet connections at data rates up to 53K
bps* over standard telephone lines. K56flex 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 transmis-
sions, and transmissions between client modems, are limited to data
rates of 33.6K bps, as are downstream transmissions that are convert-
ed more than once on the telephone network.
K56flex is an interim standard. However, because Multi-Tech’s K56flex
modems are flash-upgradeable, they can easily be upgraded to the new
ITU-T V.90 56K bps standard when it becomes available.
Both modems are Plug and Play-capable, with interactive automatic
dialing and command mode configuration. In standard mode, you can
store up to four command lines or telephone numbers of up to 40 char-
acters each in the modems’ nonvolatile memory. In callback security
mode, you can store up to 30 passwords and dialing strings. The mo-
dems pulse- or tone-dial, and recognize dial tones and busy signals for
reliable call-progress detection. The modems can detect AT&T calling
*Though these modems are capable of 56K bps download performance, line im-
pairments, public telephone infrastructure, and other external technological fac-
tors currently prevent maximum 56K bps connections.
