Abstract
An arrangement of coupled hybrid rings is disclosed which can withstand a failed node or a cut ring in either or both of the hybrid rings, as well as an outage of one of the two serving nodes utilized to interconnect the hybrid rings. The pair of serving nodes are interposed in each of the hybrid rings and serve to transmit signals between the two rings to satisfy the hybrid ring requirement of having equivalent signals propagating in two opposing directions on the unidirectional rings composing an individual hybrid ring.
