Abstract
In a network system, a duplex transmission line has two transmission lines. Each transmission line, which is connected to a transmitting section, a receiving section and a serial/parallel converter, enables data transmission to be performed in a normal operating condition. When a fault is generated in the transmission lines, the fault position is separated by a line changing section and a folded loop is formed, whereby the network system is reconstructed.
