1. A digital transmission system comprising:

  • means including bit stuffing means, for time-division multiplexing bit streams from a plurality of tributaries into a multiplexed bit stream;

    at least one of the bit streams from the plurality of tributaries being divisible into frames, each frame being divisible into a plurality of channels of equal bit length and hav1ng at 1east one additional overhead control bit;

    characterized by;

    the bit stuffing means inserts additional bits in each bit stream from the plurality of tributaries so that the number of bits per frame of said one bit stream in the multiplexed bit stream is an integer number of the number of bits per channel, and so that the number of bits per frame of each of the other bit streams in the multiplexed bit stream is an integer number of said number of bits per frame of said one bit stream long.
