摘要： A monitoring path changing method is disclosed that changes monitoring paths by sending and receiving monitoring path control information in a system having a monitoring control terminal to control and monitor plural transmission devices with use of the monitoring paths. Each of the monitoring paths corresponds to an area within a transmission channel data frame. The monitoring path control information controls the monitoring paths. The monitoring control terminal is connected to one of the transmission devices. The transmission devices are connected to each other via transmission channels so as to form a network. The method comprises steps of causing one of the transmission devices opposed by another of the transmission devices via one of the transmission channels to return monitoring path control information sent from the opposing transmission device, and causing the opposing transmission device to execute a monitoring path change when the opposing transmission device receives the monitoring path control information sent by itself.
