Switching network unit formed of a plurality of N identical elementary nodal switching networks having addresses from O to (N-1). If N is chosen smaller than or equal to fp, f and p being two predetermined integers, each elementary nodal switching network is connected to 2p other elementary nodal switching networks through internodal links. The interconnection pattern allows the switching network capacity to be increased nodal switching network by nodal switching network. When adding to the unit an additional nodal switching network, p internodal links are cut out and the free ends thus obtained are connected to the additional nodal switching network.
