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. To make sure that the connections have been 
made correctly, see your setup poster or 
.
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 required cable 
standards and may cause problems with the modem 
connection.
