* 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.3com/56k for details.
