Abstract

PURPOSE:To prevent lowering of the function due to disconnection, by providing the transmitting/receiving part having two I/O ports in each terminal to adopt the link constitution, in the time division multiplex transmission and receiving system for transmission and reception of information of the car, the airplane, the building, and so on. CONSTITUTION:Central transmitting and receiving controller 15 and two digital signal transmitting and receiving parts 16 and 16' are connected into a loop to constitute the system, and controller 15 has two or more data I/O terminals 19 and 20, and the system can be extended. Time division multiple signal I/O terminals 21-26 of controller 15 and digital transmitting and receiving parts 16 and 16' are used as input terminals as well as output terminals and become output terminals or input terminals according to the sequence programmed preliminarily, and the timing is controlled by the frame synchronizing signal and the timing clock signal transmitted from controller 15. There are two kinds of signal, namely, the positive frame and the inverted frame, and both frames are inverted, and thus, the function of the system is not lowered even if the transmission line is disconnected in one position.
