Abstract
The invention relates to a switching network enabling a plurality of bothway I/O links to be interconnected. In one embodiment of the invention, the network includes at least two nodes, each node possessing not more than k incident I/O points, k.gtoreq.2, n sets of k extended I/O points, n.gtoreq.2, and extension/concentration devices enabling each of the k incident I/O points to be connected to one of the extended I/O points of each of the n sets. Each bothway I/O link is capable of being connected to one of the incident I/O points of one of the nodes, and each node is associated with a bothway switching matrix having k I/O ports. The nodes are interconnected in pairs by first and second one-way switching matrices each having k input ports and k output ports.
