Claims10
A transmission apparatus comprising:
- a mapping unit configured to map a client signal received from a client apparatus into a first frame;
- a detection unit configured to detect a free space indicating an area which is unoccupied by the first frame from a payload area of a second frame into which the first frame is mapped;
- and
- wherein the mapping unit is configured to:
- map the first frame into the payload area of the second frame, and
- map a first error correction code for detecting an error of the client signal into the free space of the second frame, when the free space is detected;
- an addition unit configured to add a second error correction code for detecting an error of the second frame to the second frame into which the first frame and the first error correction code are mapped;
- and
- a transmission unit configured to transmit the second frame to which the second error correction code is added.
