ABSTRACT:
A delay-in-frames correction system in a switch unit in a PCM transmission line is used for data communication. A channel data storage unit is provided to temporarily store data corresponding to each channel on the output side or the input side of the switch unit in each direction in the PCM transmission line. A data delay control unit delays data among the data corresponding to channels and stored in the channel data storage unit. The data corresponding to a plurality of channels is output in order in the same frame and delayed by the number of frames indicated by the most delayed data corresponding to channels to provide frame correction instruction information for outputting a data string in the same frame.
