MULTIPLEXING APPARATUS HAVING BSI-CODE PROCESSING AND BIT INTERLEAVE FUNCTIONS ABSTRACT OF THE DISCLOSURE A multiplexing apparatus of a bit interleave type for time-division multiplex on PCM signals of a plural- ity of channels bit by bit to convert the PCM signals into a high-speed PCM signal. To maintain the advantage of the synchronous multiplex system, the multiplexing apparatus has a BSI-code processing function and a bit interleave function and comprises: a BSI-code adding circuit for adding BSI codes to the PCM signals before multiplexing; a BSI-code position shifting means circuit for shifting the positions of the BSI codes in the PCM signals to different positions respectively with respect to the PCM signals of a plurality of channels; and a multiplexing circuit for multiplexing the outputs of the BSI-code position shifting circuit by a bit-interleave mode.
