Welcome to 56K*Information Access

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-compliantmodems 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.

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-speeddownloads. The ITU V.90 standard was officially determined in February, 1998 and is expected to be ratified in September, 1998. Seewww.3com.com/56k for details.
