Welcome To 56K* Information Access - 3Com 56K User's Manual And Reference

ELCOME TO
The International Telecommunications Union (ITU)
decides the technical protocols that communications
devices must use to operate with each other.
Modems that comply with ITU standards can "talk"
to other standards-compliant modems and fax
machines worldwide.
The ITU has determined a worldwide standard for
56K modem technology. With a U.S. Robotics
modem, you can get 56K Internet access from any
service provider who offers the ITU V.90 standard
or 3Com's proprietary 56K technology. 3Com is
working with providers everywhere to quickly
upgrade their service to the ITU V.90 standard.

NFORMATION
∗ In accordance with the ITU standard for V.90
transmissions, this modem is capable of 56 Kbps
downloads. However, the download speeds you
experience may be lower due to varying line
conditions and other factors. Uploads from users to
server equipment travel at speeds up to 31.2 Kbps.
An analogue phone line compatible with the ITU
V.90 standard or 3Com's proprietary 56K
technology, and an Internet provider or corporate
host site with the ITU V.90 standard or 3Com's
proprietary 56K technology are necessary for these
high-speed downloads. The ITU V.90 standard was
officially determined in February, 1998 and is
expected to be ratified in September, 1998. See
www.3com.com/56k for details.
