Abstract

Modular expandable digital switching network in ATM (Asynchronous Transfer Mode) technology for a fast packet-switched transmission of information. The switching network has a J.times.J array of pre-switching modules and a 1.times.J array of final switching modules. The inputs of the switching network are connected to primary inputs of the pre-switching modules, whose outputs are connected to expansion inputs of pre-switching modules in the same column of the subsequent row. The outputs of the pre-switching modules in the final row with index J are connected to the inputs of the final switching modules in the same column, whose outputs are connected to the outputs of the switching network. Thus, a modular expandable switching network in ATM technology can be realized with minimal wiring requirements.
