The physical settings of the analogue interfaces can be made here:

Pulse:	A checked check box enables the recognition of pulse dialling on the relevant interface.
Reverse:	A checked check box inverts the wiring of the relevant interface. This is only necessary in the event of incompatibility of the terminals, since some terminals (for example, in the US) are wired the opposite way.
Receive gain:	Set the loudness a user receives at this interface. Default is -10dB for short lines and -7 db for long lines.
Transmit gain:	Set the loudness a user transmits at this interface. Default is -3dB for short lines and 0 db for long lines. Some fax devices may need a lower transmit level to avoid clipping.
Country:	Set the line impedance for different countries. In Europe CPTR21 is used.
Metering pulse frequency:	currently unused ???
