Claim Text:
1. A transmission apparatus, comprising: a clock generator that generates a clock; a receiver that receives a plurality of pieces of asynchronous data from a plurality of clients connected to the transmission apparatus via a first network; a first mapping circuit that maps the plurality of pieces of asynchronous data received by the receiver to ODU (Optical channel Data Unit) k (k=0, 1) frames; a second mapping circuit that maps the ODUk frames to a cross connection frame; a cross connection switch that cross-connects the cross connection frame obtained by the second mapping circuit by using the clock generated by the clock generator; and a transmitter that transmits a frame including data obtained from the cross connection frame output from the cross connection switch to another apparatus connected to the transmission apparatus via a second network, by using the clock generated by the clock generator, wherein the second mapping circuit maps the ODUk frames in synchronization with the clock with which transmission of the frame is synchronized by the transmitter.
