Abstract

PURPOSE: To improve the throughput of a communication system by causing a line control part to decide the restoration of the line at a flag detection time and receive and display a flag newly and causing an interface control part to detect the flag and report the normalcy of the line to a data channel unit.
CONSTITUTION: When detecting anomaly occurrence, line control part 202 stops the receiving operation and writes an executing address at final address #n307 and sets information indicating an anomaly occurrence cause to line status #n305. Meanwhile, interface control part 200 reads line status #n305 in control part 202 and sends it to a data channel unit and reports that an anomaly has occurred in data block receiving. Next, control part 202 decides that the data line has restored its normalcy when the flag is detected. Then, control part 202 erases fault information of status #n305 and sets a flag receiving display newly, and control part 200 detects it and reports the normalcy of the line to the data channel unit. As a result, the throughput of the communication system can be improved.
