Highlights
Increased Upload Speeds. With the V.92 MultiModem ZDX
desktop modem, you can achieve an upload speed of 48K
bps (30% increase over V.90 modems). This higher upstream
speed reduces data transfer time for large e-mails with
attachments and for ftp site uploads, as well as improves
operation for interactive applications.
V.44 Compression. V.44 is a data compression standard that
improves the current V.42bis data compression anywhere
from 20 to 60 percent, up to as much as 200 percent for
certain types of highly compressible data. This compression
technique, used by the V.92 MultiModem ZDX desktop
modem, enables data throughput rates of higher than 300K
bps - much faster than today's typical rates of 150 - 200K
bps. For users, it means that your Web browsing will be much
faster.
Integrated Voice, Data Communications and Fax Software.
Includes powerful data and fax communications software
with an easy-to-use graphical interface for Windows 95/98/
Me/XP/2000/2003. And when used with the voice models,
you can take advantage of voice messaging and full-duplex,
hands-free speakerphone features.
Consolidate Space and Power Requirements. For applications
that require rackmounting, the MultiModem ZDX desktop
modems are ideal. All models have a rackmountable chassis
that consolidates space and power requirements for up to
twelve modems when using the Multi-Tech ZDXRack.
Comprehensive Service and Support. The Multi-Tech
commitment to service means we provide a ten-year product
warranty and service that includes free telephone technical
support, 24-hour web site and ftp support.
