ABSTRACT:
Three-stage, at least doubled ATM switching network. A method for expanding a three-stage, stretched and at least doubled ATM self-routing switching network, the switching matrices of the second switching stage can be respectively doubled in one redundancy level after another without interrupting operation given a simultaneous, respective halving of the plurality and filling of link groups formed from the very outset and proceeding between the first switching stage, the second switching stage and the third switching stage, of which link groups only links of one and the same group of links are occupied for every connection lasting during an expansion of the switching network.
