Abstract
A communicating method for a data communications apparatus capable of transmitting data in a full-duplex mode over a two-wire circuit. Prior to the transmission of data, a transmit and a receive terminals exchange training signals to test circuit conditions in order to see if full-duplex communication therebetween is allowable. Depending upon the result of the test, either a full-duplex mode or a semiduplex mode is set up for data communication.
