<p>When a first communication device receives a predetermined message from a second communication device via a third line in a state of transmitting frames to a first line while performing error-correction coding on the frames, the first communication device switches the line to a second line after transmitting a frame of a post-switching message to the first line, and continues transmission. The second communication device receives the frames from the first and second lines and performs error correction, stores the frames, on which error correction has been performed, in first and second buffer, and when determining that it is necessary to perform line switching based on the status of error correction with respect to the frames received from the first line, transmits a predetermined message to the third line, and when receiving the frame of the post-switching message from the first line, starts reading of the frames from the second buffer after reading all of the frames stored in the first buffer.</p> |
