    摘要: A first reception processing unit performs a process of receiving a first signal transmitted on a first transmission line, a second reception processing unit performs a process of receiving a second signal transmitted on a second transmission line, and an output speed control unit controls output speeds of the first signal and the second signal subjected to the reception process. A system switching unit selects and outputs the first signal or the second signal subjected to a reception process, and an output processing unit performs a process for output to another apparatus on the output from the system switching unit. A reception side clock output unit outputs a clock signal giving a processing timing of each process, and a clock frequency control unit adjusts a frequency of the clock signal giving the processing timing to the output processing unit. A frequency adjustment range calculation unit calculates an adjustment range of the frequency based on frequency deviation accuracy of the reception side clock output unit, frequency deviation accuracy of a transmission side clock output unit that outputs a clock signal giving a processing timing to a transmission process at a transmission apparatus on the transmission side, and a prescribed value of a frequency deviation.

    摘要: An output port switching unit that connects to a first optical transmission path, a second optical transmission path, and the connection information processor, and sets a destination of the first optical transmission path as the connection information processor in an initial state. A controller that transmits transmission mode information indicating a transmission mode identified based on connection information of the first optical transmission path acquired from an optical signal transmitted by an optical transceiver provided in an optical communicator that the connection information processor connects to the first optical transmission path, connection request data included in the optical signal and transmitted by the optical transceiver, and transmission path information of the second optical transmission path to the optical transceiver through the first optical transmission path. The output port switching unit performs switching processing of switching a destination of the first optical transmission path from the connection information processor to the second optical transmission path after the controller transmits the transmission mode information.
