WELCOME TO 56K* INFORMATION ACCESS
1
The International Telecommunication 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, V.90. 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.
∗∗ In accordance with the ITU standard for V.90
transmissions and 3Com 56k x2 technology, 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
56K x2 technology, and an Internet provider or
corporate host site with the ITU V.90 standard or
3Com 56K x2 technology are necessary for these
high-speed downloads.
