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 computer has a v.90 modem, the speed at which you can upload (send) data is limited
to 33.6K. If your computer 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 computer
•
Make sure that the line connected to the modem is working and plugged into the
appropriate port on your computer. See
“Back” on page 7 or your setup poster to make
sure that the connections have been made correctly.
•
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 computer. Some telephone cables do not meet
