PROBLEM
Your 56K modem cannot achieve a 56K Internet connection.
POSSIBLE SOLUTION
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 V.90 standard or 3Com 56K technology, and an Internet provider or corporate host site
compatible with the V.90 standard or 3Com 56K technology are necessary for these high-speed
downloads. Check http://www.3com.com/56k for a list of ISPs that observe the 56K ITU
standard and/or offer 3Com 56K technology.
POSSIBLE SOLUTION
The phone lines in your area may not be 56K compatible. Call your phone company to find out
if your phone line is compatible with the ITU standard for 56K and/or is compatible with 3Com
56K technology.
POSSIBLE SOLUTION
You may have devices between the modem and the phone jack. There should be no line
splitters, fax machines, or other devices between the modem and the wall jack.
