Realization of a PCM switching stage
Abstract
A description is given of the realization of a time division digital switching stage for 1024 PCM channels. The stage has full accessibility and no internal blocking. It has a time division structure only, based on fast memories and a multiplexer with an input/output matrix. The operation of the system is illustrated by means of time domain drawings and diagrams. Mention is also made of the circuit techniques and configurations adopted. In conclusion, consideration is given to the performance of the stage, which is intended to be used in prototypes of electronic switching equipment.
