摘要:
PROBLEM TO BE SOLVED: To perform BIP operation easily while keeping matching with an existing system when data of different bit rates are transmitted mixedly. SOLUTION: The header information of a basic bit rate is added, to data signals of a basic bit rate and other bit rate (42a, 42b) to constitute a data string by time division multiplexing even for the data signal to which the header information is added (43). Furthermore, frame signals are constituted by adding frame headers (44a, 44b), a parity of the frame signals constituted continuously is calculated (45) and based on operation results of the parity, parity bits for the parity check of the data signals of the basic bit rate and the other bit rate are inserted into the frame signals (46, 47).
