be plugged into the jack labelled on the modem and into the wall
phone jack. Use the phone cord included in your modem's box if
possible.
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.
Office Users Possible solution:
You may have plugged your modem's phone cord into a digital line,
which can damage your modem. Contact your phone system
administrator if you are unsure whether or not your phone line is digital.
If your phone system requires dialing “9” to access an outside line, be
sure to add “9” before the number you are dialing.
Dialing Problems for
Voice Mail Users
Possible solution:
If you have voice mail provided by your local phone company, your dial

connect to another
modem but fails.
Possible solution:
You may have a poor connection. All calls are routed differently, so try
placing the call again.
My modem isn't
achieving a 56K
Internet connection.
Possible solution:
Note: U.S. Robotics 56K modems are capable of receiving downloads at
up to 56 Kbps and sending at 31.2 Kbps. Actual download speeds you
experience may be lower due to varying line conditions. Maximum
download speeds in U.S. and Canada are limited to 53K, due to
regulatory limits on power output.
Our research has shown that the vast majority of telephone lines in North
America can and do support 56K installation. The V.90 protocol allows
for connection speeds of up to 56K, but line conditions may affect the
actual speeds during a given connection. Due to unusual telephone line
