Abstract: PURPOSE:To use a wired line in common for state supervision and phase supervision use by providing a changeover switch of a transmission line and a control section switching the changeover switch automatically to a peripheral fixed station. CONSTITUTION:A signal generator 3 in a central control station 1 generates a signal string 100 by a command of a central control section 2 and sends it to wired lines 8, 10 through delay devices 4, 5. On the other hand, when control sections 16, 17 of a peripheral fixed station receivers the signal string 100, a modulation signal 101 is radiated from transmission antennas 14, 15, a state report signal 201 is generated and sent to wired lines 9, 11 and a phase synchronizing signal 102 is reflected. Supervising devices 6, 7 receiving a signal string 200 measure a time difference between a phase synchronizing signal 102 and sent from the signal generator 3 and a phase synchronizing signal 202 sent back and it is informed to a central control section 2. The central control section 2 sets a proper delay to the delay devices 4, 5 based on the time difference. Thus, an exclusive wired line or radio receiver is not required.
