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.
The modem is not recognized by your notebook
•
Make sure that the line connected to the modem
is working and plugged into the appropriate port
on your notebook. For the location of your
optional modem jack, see
“Back” on page 9

•
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 a different modem cable. Some telephone
cables do not meet required cable standards and
may cause problems with the modem
connection.
•
Shut down and restart your notebook.

Phone
and Modem Options
