Abstract
In a time-division multiplex switching network unit for time-space switching which operates employing an information memory which has information input thereto in a cyclic manner and read therefrom in a random fashion, the number of terminals is limited, in particular, by the fact that during random output it is not possible to exceed a specific speed. Higher number of terminals are achieved in that the switching network units are composed of modules whose corresponding inputs are connected to one another and into which, during each pulse frame, more PCM words are input than are output. In this manner, the reading frequency is kept low, although, because of the multiple connection at the input end, blocking-free switch-through is provided.
