PROBLEM TO BE SOLVED: To provide a demultiplex transmission system which simplifies its constitution and makes effective the frame transmission. SOLUTION: The demultiplex transmission system has a separator and a multiplexer. The separator divides a communication frame, including an overhead having n (n>=2) small overheads which include synchronizing information and information data into n small communication frames, based on the length of the small overhead. The small communication frames are transmitted over n predetermined transmission lines, corresponding to the sequence of the synchronizing information to the multiplexer. The multiplexer multiplexes the n small communication frames, based on the synchronizing information in each small communication frame and on the sequence of the synchronizing information and corresponding relation of the transmission lines to this sequence. |
