Abstract

PURPOSE:To achieve transmission for each multiplex converter from two systems of terminal devices at the same time and reception through a terminal station without failure, by constituting the two systems of transmission lines tying a master station and a plurality of slave stations in a closed loop. CONSTITUTION:A transmission signal from a slave station 20a to a master station 10 is applied from a transmission terminal T of terminal devices 31, 32 of the 1st and 2nd systems to both multiplexers in multiplex converters 22, 21 of the 2nd and 1st systems. The transmission signal with multiplex is transmitted to the next station via cables 41, 42 of the 1st and 2nd systems. A signal transmitted from the slave station 20a to the master station 10 via the 2nd system cable 42 is inputted to a separation section D in the 1st system multiplex converter 12. On the other hand, a transmission signal transmitted to the 1st system cable 41 from the slave station 20a is inptted to the separation section D in the 2nd system multiplex converter 13. signals outputted from reception terminals 1-n of the section D are respectively inputted to reception terminals R1-Rn of terminal devices 51, 52.
