ABSTRACT:
A multi-stage space-division switching network comprises groups of regenerators (RE1 to RE16) connected to input lines and to output lines of the switching network, it further includes groups of regenerators (RS1 to RS16) connected to a first end of intermediate links (LI1 to LI28) interconnecting two stages and groups of regenerators (R3.1 to R3.16) connected to the other ends of the intermediate links. A monitoring device comprises sampling devices (P) connected to the groups of regenerators and to a comparator circuit (CC). A main marker (MQP) receives connection instructions and sampling instructions and transmits these instructions to auxillary markers (MQ) which control the sampling circuits (P) and the switching circuits (C1, C2) of the switching network.
