Abstract
Communications circuit connectivity between a bidirectional line-switched ring transmission system and another ring transmission system is continued in the presence of the failure of a first shared node for communications circuits between the ring transmission systems by employing at least one additional shared node for the communications circuits; provisioning one or more duplex communications circuits between the first shared node and the additional shared node; and selectively allowing the one or more duplex communications circuits between the shared nodes to be established in the bidirectional line-switched ring when a ring node in the bidirectional line-switched ring in the first shared node has failed.
