Abstract
A first transmission device transmits a signal to a third transmission device by using an active line and a spare line. The first transmission device includes a CRC generator and an SN adder. The CRC generator calculates the CRC value of the signal. The SN adder stores, in a FCS byte filed in the signal, the FCS calculated value obtained by adding the SN representing consecutiveness of the signal to the CRC value. Furthermore, the first transmission device outputs the signal in which the FCS calculated value is stored to the second transmission device by using the active line and the spare line.
