Upgrading to x2 Technology
Be sure to read the section titled "U.S.
Robotics Modem Update Wizard" on page
101 for information on upgrading your 33.6
™
faxmodem to x2 technology, allowing
downloads of up to 56 kbps*.
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.
