ABSTRACT:
In transferring a supervisory right requirement signal in a submarine cable communication network system comprising a plurality of stations, a particular one of the stations being connected with other ones of the stations as opposite stations through submarine cables including repeaters, the particular station transmits a particular signal representative of the supervisory right requirement assigned thereto to the opposite stations through the submarine cables, respectively. Each of the opposite stations receives the particular signal as a received particular signal. Each of the opposite stations discriminates from the received particular signal that the particular signal is transmitted from the particular station. Then, each of the opposite stations returns the received particular signal to the particular station as a specific signal. The particular station receives the specific signal from each of the opposite stations as a received specific signal. When the particular station discriminates that the received specific signal is equal to the particular signal, the particular station acquires the supervisory right for the repeaters included in the submarine cables. The particular station can acquire the supervisory right without any back-up line when any fault occurs at a point in the submarine cable connecting between opposite stations.
