∗ 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 analogue phone line compatible with the ITU-T 56K standard technology, and an
Internet provider or corporate host site compatible with the ITU-T 56K standard or K56Flex
technology are necessary for these high-speed downloads.
