Diagnosis:
The phone line might be wired incorrectly.
Possible Solution:
Contact the telephone company and ask them
to make sure the tip and ring are on the inside
pair of wires.
PROBLEM:
Your modem cannot achieve a 56K
Internet connection.
Diagnosis:
Your modem is capable of receiving up to 56
Kbps and sending up to 31.2 Kbps. Due to
FCC regulations, receiving speeds are limited
to 53 Kbps. Actual speeds may vary. An
analog phone line compatible with the 56K
ITU standard or x2 technology, and an
Internet provider or corporate host site
compatible with the 56K ITU standard or
x2™ technology are necessary for these high-
speed downloads.
Possible Solutions:
Check

for a list
of ISPs that observe the 56K ITU standard
and/or offer x2 technology.
Call your phone company to find out if your
phone line is compatible with the ITU-T
standard for 56K and/ or is
x2-compatible. You can also run
the U.S. Robotics Line Test utility to determine
if your line is compatible. To run the test, visit
