ABSTRACT:
A multiplexer for combining a plurality of relatively sparsely occupied DTDM bit streams into a smaller number of more densely occupied DTDM bit streams at the same bit rate is disclosed. The input lines of the multiplexer are divided into groups so that DTDM frames arriving on the input lines in one group are combined to form one outgoing DTDM bit stream. The outgoing DTDM bit streams are formed by synchronously generating chain of empty frames for each of the input line groups. The frames in a chain are passed to a first member of the appropriate input line group and by means of a cross-point switch to each succeeding member for the insertion of data. The groupings of input lines are defined by the settings of the cross-point switch and may be rearranged by changing the settings of the switch.
