Welcome to 56K* Information Access
The International Telecommunication
Union (ITU) determines 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 decided on a worldwide
standard for 56K modem technology.
With a 3Com U.S. Robotics modem, you
can get 56K Internet access from any
service provider who offers the ITU
V.90 standard or 3Com 56K technology.
3Com is working with providers
everywhere to quickly upgrade their
service to the ITU V.90 standard.
* IMPORTANT! In accordance with the ITU
standard for 56K transmissions (V.90), this
modem is capable of 56 Kbps downloads.
However, due to varying line conditions, the
actual speeds you experience may be lower.
Uploads from users to server equipment travel at
speeds up to 31.2 Kbps. An analogue phone line
compatible with the V.90 standard and an
Internet provider or corporate host site
compatible with the V.90 standard are necessary
for these high-speed downloads. See
