POSSIBLE SOLUTION
You may be using the wrong power adaptor for your modem. Use only the power adaptor that came with your
modem.
PROBLEM
Both modems sound like they are exchange carrier signals, but fail to establish a connection.
POSSIBLE SOLUTION
You may have a poor line connection. Place the call again. Calls are routed differently each time.
PROBLEM
Your 56K modem cannot achieve a 56K Internet connection.
POSSIBLE SOLUTION
Your modem is capable of receiving data at speeds up to 56 Kbps and sending data at speeds up to 31.2 Kbps.
However, the download speeds you experience may be lower due to varying line conditions. An analogue phone
line compatible with ITU-T V.90 or 3Com 56K technology, and an Internet provider or corporate host site
compatible with ITU-T V.90 or 3Com 56K technology are necessary for these high-speed downloads. Check
http://www.3com.com/56k for a list of ISPs that observe ITU-T V.90 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 ITU-T V.90 and/or is compatible with 3Com 56K technology.
