ABSTRACT:
A switching system for telephone exchanges employing pulse code modulation (PCM). The time division switching network uses standard circuits of a single type, i.e., symmetrical time division matrices (MTS) and, in a particular embodiment, one PCM telephone junction is multipled onto two inputs of two MTSs and the latter are rejoined by two bi-directional junctions so that the construction of telephone exchange according to the invention permits simple and easy extensions of the capacity of the switching system.
