Abstract

PURPOSE:To allow an opposite station to quickly detect a fault and to quickly restore a system, by providing the titled equipment with a function for detecting a fault generated in a master device side and informing the fault to the opposite station through a line. CONSTITUTION:When a fault such as clock down is detected by a receiving circuit 102, a detecting output indicating the fault is informed to a frame forming part 104 as an interruption. The frame forming part 104 recognizes the generation of the fault in a data processor of its own station, forms a frame indicating the generation of the fault and outputs the frame to a transmission circuit 106. The circuit 106 sends the frame received from the forming part 104 to the opposite station through a line 20 to inform the generation of the fault. Consequently, the opposite station can detect the fault quickly and restore the system quickly.
