Title: DATA TRANSMISSION METHOD AND APPARATUS
Abstract:
Disclosed is a data transmission method. The method comprises: a receiving end receiving a data stream sent by a sending end, and detecting synchronization codes in the data stream, wherein the data stream is formed after various pieces of service data are multiplexed/demultiplexed by the sending end to sub-channels of a low-speed data channel according to a pre-set frame multiplexing/demultiplexing structure; determining whether N synchronization codes are continuously detected, wherein every two synchronization codes are spaced apart by m bytes, and m and N are positive integers; and if the N synchronization codes are continuously detected, multiplexing the data stream according to the frame multiplexing/demultiplexing structure of the data stream so as to obtain service data corresponding to the sub-channels of the low-speed data channel. Further disclosed is a data transmission apparatus. According to the present invention, various pieces of service data are simultaneously transmitted on a low-speed data channel, and the function of simultaneously transmitting various pieces of service data on a single low-speed data channel is realized.
