Bit 1: 0, Bit 0: 0 = None
Bit 1: 0, Bit 0: 1 = Low
Bit 1: 1, Bit 0: 0 = Medium
Bit 1: 1, Bit 0: 1 = High
Use a higher setting if there is signal loss at higher
frequencies because of the length of wire between
the modem and the telephone exchange.
Use the dedicated transmission parameters for
specific receivers.
Also, try using the cable equalizer if one or more of
the following symptoms occurs.
