Abstract
A method of operating a switching network, a switching network, and an exchange with such a switching network are described. The switching network consists of several switching modules and an interconnect network between these switching modules. The interconnect network includes a switch unit and interconnects the switching modules in accordance with a logic interconnection structure. The switch unit is simple and can be implemented by all-optical means. By means of the switch unit the logic interconnection structure can be reconfigured. This makes it possible to reconfigure the switching network in the event of a failure of a switching module or according to the load characteristic (video, voice, computer-computer communication). Further, a uniform switch unit can be used to meet different requirements ('flexible hardware').
