Abstract

A digital switching device of the stored programme type has an input time switching stage 15, an output time switching stage 16, a space switching stage 17 intermediate the time switching stages and a central control unit 25. Each time switching stage has a connection store (174, 174') - Figs. 12, 15 (not shown) - and the space switch Fig. 16 (not shown) has comparison means (314, 315) linked to the connection stores (174, 174'). The comparison means compares the contents of connection stores and controls the operation of the space switch on the basis of this comparison. <IMAGE>
