In a transmission system for bi-directionally transmitting and receiving a plurality of signals between two units (1), (2) interconnected through a predetermined transmission path (3), if one of the plurality of signals falls into any of a transmission disabled state, a transmission not required state, a reception disabled state, and a reception not required state, at least one of a transmission operation and a reception operation for the signal in the one state is stopped or set into a stand-by state, thereby reducing electric power consumed by the transmission system. In addition, a transmission bandwidth of the transmission path is reduced by a portion associated with the signal in the one state, or an entire bandwidth for all signals except for the signal in the one state is expanded without changing the transmission bandwidth of the transmission path. <IMAGE> |
