Abstract
A transmission device includes a receiver receiving a signal transmission frame from a network, where a client signal is mapped to the signal transmission frame; a separator separating the client signal from the signal transmission frame; a phase synchronizer generating a clock based on a frequency adjustment information set of the client information included in the signal transmission frame; a transmitter transmitting the client signal to a client transmission path by using the clock generated by the phase synchronizer; a memory storing the frequency adjustment information set included in the signal transmission frame in response to receiving the signal transmission frame from the network by the receiver; and a switch controller causing the phase synchronizer to generate a clock based on the frequency adjustment information set stored in the memory in response to not receiving the signal transmission frame from the network by the receiver.
