Abstract

PURPOSE:To easily enable to discriminate the causes and types of failure with frame synchronism, by transmitting the failure information on a transmission line with the timing signal via a gate circuit of a line concentration stage interface section. CONSTITUTION:A transmission format is formed with a frame synchronism F, channel data and failure information. Various failure information A, B, C are respectively informed from failure informing lines 11-13, and since the timing signal from a failure informing timing generating circuit 20 is transmitted on timing lines 17-19 at the time of k+1, k+2 and k+3, the information indicating the failure at this time in the transmission frame can be transmitted. Thus, a branch stage controller 109 can discriminate the device in failure and the causes to failure, by identifying the time in the transmission frame inserted with the failure information.
