* IMPORTANT! In accordance with the ITU-T standard for 56K transmissions (V.90), U.S. Robotics 56 Kbps
modems are capable of 56 Kbps downloads. However, due to FCC rules which restrict power output of service
providers, current download speeds are limited to 53 Kbps. Actual speeds may vary due to line conditions and
other factors. Uploads from users to server equipment travel at speeds up to 31.2 Kbps. An analog phone line
compatible with the V.90 standard or x2 technology and an Internet provider or corporate host site compatible
with the V.90 standard or x2 technology are necessary for these high-speed downloads. See www.3Com.com/56k
for details.
