* 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.
