Abstract
In a ring network system including two transmission lines transmitting a signal in directions opposite to each other, and a plurality of line concentrators connected in the form of a loop by the two transmission lines and each accommodating a plurality of terminal stations connected to one of the two transmission lines, a signal detecting unit and a terminating circuit are disposed in each of the line concentrators on the signal output side of each of the transmission lines so as to be connectable to and disconnectable from the transmission lines, so that, when the signal detecting unit in one of the line concentrators is connected to the associated transmission line, the transmission line is disconnected in the line concentrator, and the terminating circuit is connected to the downstream segment of the disconnected transmission line.
