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. See
