Use a higher setting if there is

because of the length of wire
between the modem and the
telephone exchange when calling
the number stored in this
Quick/Speed Dial.
Also, try using the cable equalizer if

symptoms occurs.
Communication error with error
codes such as 0-20, 0-23, etc.
Modem rate fallback occurs
