Abstract

1,171,075. Automatic exchange systems. SIEMENS A.G. 26 Feb., 1968 [27 Feb., 1967], No. 9108/68. Heading H4K. A cross-point switching network which comprises two stages A, B and a number of sections KG1, KG2 ... KGq, Fig. 1, is controlled by a simulating relay network, Fig. 2 (the relays being shown only for switches KA11, KB11), wherein the horizontals in each section of stage A are connected in multiple to marking wires mq, the verticals in each section of stage B are connected in multiple to marking wires qr, and the corresponding links between the verticals of A and horizontals of B in the several sections are connected in multiple to marking wires np. The marking wires are controlled by relay matrices SF1, SF2, SF3.
