Abstract

PURPOSE:To attain a surer remote control by making the remote control circuit between an advancing base station side and a terminal side by the double line of a radio channel and a wire channel. CONSTITUTION:A remote control line connecting an advancing base station side 8 and a terminal side 9 is made the double line of a wire channel 10 and a radio channel 11. When a fault occurs in a using remote control line (either one of the wire channel 10 or the radio channel 11), for instance, the remote control line is made to be automatically switched to the other channel. Namely, when the wire channel 10 is disconnected when the channel is used, the use is automatically switched to the radio channel 11, and when the radio channel 11 is disconnected when the channel is used, the use is automatically switched to the wire channel 10. By a remote control device 20, either one of the use of the remote control line of the radio channel or the wire channel can be arbitrarily switched and selected. But, when the channel to be selected has already been failed, a switch operation is not performed.
