ABSTRACT:
An enhanced form of time switch. Serial bit streams received in input buffers are stored in parallel under program control in the cache of a pipe lined microprocessor. The microprocessor, under program control, then rearranges the received time slots and feeds them in parallel to output buffers from which serial bit streams are generated. Advantageously, program control is used to flexibly control the various functions of different time switches without requiring a change in the hardware.
