■ Make sure the line connected to the modem is working and plugged into
the appropriate connection on the modem. Use the Setup poster to make
sure that the connections have been made correctly.

the telephone line is not in use (for example, someone is on the
telephone, or another modem is in use).
■ Use the modem cable that came with your computer. Some telephone
cables do not meet required cable standards and may cause problems with
the modem connection.
■ Shut down and restart your computer.

■ Reinstall the device driver. For instructions, see “Reinstalling device
drivers” on page 68.
