ABSTRACT:
In a switching module for a digital cross-connect system, N input terminals of the module are divided into first and second groups and N output terminals are likewise divided into first and second groups. First and second N.times.N space switches and a first group of N selectors are provided. Each of the first-group selectors has a first input coupled to an associated one of the N input terminals of the first group and an output coupled to an associated one of N inputs of the first N.times.N space switch. A first group of N splitters are connected respectively to the N input terminals of the second group, each of the splitters having a first output coupled to a second input of an associated slector of the first group and a second output coupled to an associated input of the second N.times.N space switch. A second group of N selectors is provided, each having a first input coupled to an associated output of the first N.times.N space switch and an output coupled to an associated output terminal of the first group. A second group of N splitters are connected respectively to N outputs of the second N.times.N space switch. Each of the second group splitters has a first output coupled to a second input of an associated selector of the second group and a second output coupled to an associated output terminal of the second group.
