Section One - Introduction
Your modem represents a new generation of PC communication peripheral devices, combining high
speed Data and Fax functions into a single device. It supports V.90 and K56flex technology for 56kbits/s
data transfer rates. This high performance modem connects your computer to all popular modems and
fax machines in use today.
How Does K56flex Work
V.90 technology allows users to receive data from their Internet Service Provider (ISP) at data
rates up to 56kbps. To make use of this capability, your ISP must support either the V.90 or the

digital connection to the telephone network to realize speeds reaching 56kbps. 56kbps cannot be
achieved in a connection between two end user modems because each uses an analog
Benefits of 56K Communications
For serious Internet users the increase in speed is dramatic, because the information that usually
makes you wait – graphics-heavy Web pages, sound, video, and other large files – now
downloads to your computer twice as fast as before. Upstream transmissions (mostly keystroke
and mouse commands from your computer, which require less bandwidth) continue to flow
quickly at the conventional rate of 33.6Kbps.
