ABSTRACT:
The invention relates to a broadband space switching network and to a parallel-series converter and to a series-parallel converter in combination with such a space switching network. The crosspoints of the space switching network are set once per n-bit word. So as to find the time required therefor, each word contains (n-n.sub.1) "idle" bits, n.sub.1 representing the number of information bits. During the time in which the "idle" bits are transmitted, the space switching network is switched to the desired new state. The parallel-series converter, which is also required for other reasons, is used to inject "idle" bits into the bit stream conveyed to the space switching stage. The "idle" bits are removed again by means of a series-parallel converter at the output of the space switching stage.
