A multistage digital switching network for use in telecommunications has two identical subnetworks. Each of the subnetworks consists of three modules which are connected in series. In one embodiment, the subnetworks are connected through additional modules identical to the middle module of the series of the subnetworks. In another embodiment, otherwise unused outputs of the middle modules of the subnetworks are used for the connections between the subnetworks.
