Abstract

PURPOSE:To relieve fall down of a system, by giving a disconnection detecting function to a master station and plural remote station and performing the loop back control in remote stations adjacent to the master station when the master station is down. CONSTITUTION:A master station 1 and plural remote stations 2-5 having the disconnection detecting function are connected by transmission lines ABCDE and A'B'C'D'E' to form a transmission processing system of a transmission line dual loop. When the master station 1 becomes down to stop the transmission of signals onto the transmission line AA', adjacent remote stations 2 and 5 regard the transmission line AA' as disconnected and performs the loop back control. In this new loop transmisson processing system, a determined one of remote staions 2-5 executes the function of the master station 1. Thus, fall down of the system is avoided when the master station is down.
