Your 56K modem does not connect at 56K
Current FCC regulations restrict actual data
transfer rates over public telephone lines to 53K.
Other factors, such as line noise, telephone
service provider equipment, or ISP limitations,
may lower the speed even further.
If your notebook has a v.90 modem, the speed
at which you can upload (send) data is limited to
33.6K. If your notebook has a v.92 modem, the
speed at which you can upload data is limited to
48K. Your ISP may not support 48K uploads.
Your fax communications program only
sends and receives faxes at 14,400 bps when
you have a 56K modem
Current fax technology only supports a
maximum send and receive rate of 14,400 bps.

■ Make sure that the line connected to the
modem is working and plugged into the
appropriate port on your notebook.
■ If the modem shares the telephone line
with another device, make sure that 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
notebook. Some telephone cables do not
meet required cable standards and may
cause problems with the modem
connection.
■ Shut down and restart your notebook.
■ Run Windows modem diagnostics.
