Abstract:
Electronic equipment, comprising:a physical layer circuit having a first transmitter operable to communicate with a child node, a second transmitter operable to communicate with a parent node, and a controller operable to control said physical layer circuit such that, when said physical layer circuit receives a first signal from said child node, said physical layer circuit changes from a first state to a second state and transmits said first signal to said parent node, when said physical layer circuit receives a third signal for canceling said first signal from said child node before receiving a second signal corresponding to said first signal from said parent node, said physical layer circuit transmits said third signal to said parent node after receiving said second signal from said parent node, and when said physical layer circuit receives said third signal from said parent node, said physical layer circuit changes from said second state to said first state.
