ABSTRACT:
A non-symmetrical half-duplex data communications apparatus and method provides for transmitting and receiving non-symmetrical half-duplex signals over a communications link. The non-symmetrical half-duplex data communications apparatus includes interface circuitry that is connectable to the communications link and modulation circuitry to transmit and receive the non-symmetrical half-duplex signals over the communications link. The modulation circuitry of the non-symmetrical half-duplex data communications apparatus includes the ability to transmit data signals with a transmission time that is different than the transmission time of receive signals. The modulation circuitry of the non-symmetrical half-duplex data communications apparatus also includes the ability to transmit data signals with a transmission data rate different than the transmission data rate of receive signals.
