ABSTRACT:
An end node for which sending and receiving are controlled by a hub is directly connected and used. When another end node is directly connected to the PMD control unit 2, the input control signal processor 11 of the signal processor 1 receives a receiving state signal indicating the state of a tone signal which is outputted from the PMD control unit 2 and received from another end node, converts it to a receiving state signal indicating the state of a tone signal from the hub which has the same meaning as it, and transfers it to the MAC/PMI control unit 14.
