ABSTRACT:
A multiplexer for time division multiplexing a plurality of DTDM bit streams is disclosed. By taking advantage of the fact that the frames comprising each DTDM bit stream are not 100% occupied, the frequency of the higher speed output bit stream can be made equal to the product of the nominal center frequency of the input tributaries and the number of input tributaries. This is accomplished through the positive and negative stuffing of DTDM frames.
