摘要： PROBLEM TO BE SOLVED: To detect transmission line interruption and degradation by the presence/absence of reception of packet signals within a fixed time interval, without having to transfer an OAM (operation and maintenance) packet.SOLUTION: On a transmission side, a conversion part 212 periodically transmits main signals, without including maintenance operation signal packets. On a reception side, a transmission line fault detector 215 determines that a transmission line fault is detected, when it is determined that the next main signal is not received for the preset time, after receiving the main signal. An OAM processing part 313 detects whether it is a state of not transmitting the main signal to an opposite transmitter or an idle state, on the basis of the detection of the transmission line fault by the transmission line fault detector 215, and transmits a maintenance operation signal for notifying the transmission line fault to the opposite transmitter, when it is in an idle state.
