摘要

Conventionally, when discarded assuming bad the frame itself when there is an error in the sync header, frame synchronization has not come off, even if the error rate is low enough to be capable of error correction, error correction there is a problem that it is impossible. In accordance with the present invention, each of the subscriber side terminating device and the station-side terminating device, a synchronization detection unit for detecting synchronization in the received data that has been framed to whether out, synchronized out by the synchronous detector For a frame of received data is detected as not to include, an error correction unit that performs error correction regardless of the presence or absence of errors in the synchronization header of the frame.
