In this continuously expandable modular switching network, incoming traffic infiltrates the network only to the extent required in order to set up the desired connection. For an extension involving additional switching matrices (110, 112, 113) in two stages, there is no need to alter the internal or external connection lines. A technique is employed in which the outputs (104, 106) of the switching elements of any given stage (stage 1) are connected only to the inputs of switching elements of higher-order stages (stage 2). So-called reversal points (114, 116, 118, 120) of the aforementioned second stage are used to switch a connection. <IMAGE> |
