ABSTRACT:
The time-switching network according to the invention has an inlet stage, an outlet stage, and a selection switching stage, respectively comprising M, M, and N groups. It includes line equipments; each inlet stage group has a storage function, the same applying to each outlet stage group and each selection switching stage group. All inlet storages have access to each switching memory via one inlet selection multiplexer per switching group, the output of each inlet storage being multipled to one inlet of each such selector; all switching memories are accessible from each outlet storage via an access selector, the outlet of each switching memory being multiplied to one point of each outlet access selectors' field; the overall system is a full access (non-blocking) switching network.
