Min TX rate/Max TX rate are optional numeric values that specify the lowest value
at which the DCE may establish a connection. If unspecified (set to 0), they are
determined by the carrier and automode settings.
Min RX rate/Max RX rate are optional numeric values which specify the highest
value at which the DCE may establish a connection. If unspecified (set to 0), they
are determined by the carrier and automode settings.
