IMPORTANT!
In accordance with the ITU-T standard for 56K transmissions, this modem is capable of
56 Kbps downloads. However, due to FCC rules which restrict power output of the service providers’
modems, current download speeds are limited to 53 Kbps. Actual speeds may vary depending on 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 ITU-T 56K standard or x2
technology, and an Internet
provider or corporate host site compatible with the ITU-T 56K standard or x2 technology are necessary
for these high-speed downloads.
