∗∗ IMPORTANT! All x2 products are 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. Uploads from users to service
providers travel at speeds up to 28.8 kbps. An x2-capable modem, an x2-compatible analog phone
line and an x2-capable Internet Service Provider are necessary for these high-speed downloads.
