Abstract
A multiple-ring communication system is disclosed wherein each node of the system is adapted to collect information on the status of the system. Receiver/transmitter equipments of each of the nodes are able to transmit ring test messages on the rings, the destinations of which are the node itself. Processing equipments control the receiver/transmitter equipments of the node and are able to check the receipt or absence of receipt of the ring test messages prior to possibly executing reconfiguration operations. Receiver/transmitter equipments of each of the nodes are also able to transmit neighboring node test messages on the rings, which upon receipt by the receiver/transmitter equipments of the neighboring nodes normally give rise to the transmission to the node of node test reply messages on rings different from those on which the neighboring node test messages were transmitted. The node processing equipments are also able to check the receipt or absence of receipt of the node test reply messages prior to possibly executing reconfiguration operations.
