Abstract
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 transmis…
