Techniques for providing normal operation and service restoration capability in the event of failure of terminal equipment or transmission media in a heterogeneous network, such as a hybrid network containing single- and multi- wavelength lightwave communications systems. An optical switching node or OSN (12, 120a-d) is placed at each node in the ring network (110) to provide the required connections between various fibers (55) and terminal equipment (50, 50a-d), but having switch states that allow signals on the protection fibers to bypass the terminal equipment at that node. Ring-switched signals propagate around the ring on protection fibers (55adp', 55dap') without encountering the terminal equipment at the intervening nodes. To the extent that the protection fiber links between any given pair of nodes are incapable of supporting all the relevant communication regimes, such links are modified to provide such support.

Techniques permettant de conférer une capacité d'exploitation normale et de restauration de service en cas de défaillance de l'équipement terminal ou des supports de transmission dans un réseau hétérogène, tel qu'un réseau hybride contenant des systèmes de télécommunications optique à une seule ou plusieurs longueurs d'onde. Un noeud de commutation optique ou OSN (120, 120a-d) est placé au niveau de chaque noeud dans le réseau en anneau (110) de sorte que les connexions requises soient fournies entre les diverses fibres (55) et l'équipement terminal (50, 50a-d), ledit noeud ayant des états de commutation permettant aux signaux sur les fibres de protection de contourner l'équipement terminal au niveau de ce noeud. Les signaux commutés en anneau se propagent sur l'anneau par les fibres de protection (55adp', 55dap') sans rencontrer l'équipement terminal au niveau des noeuds d'intervention. Dans la mesure où les liaisons par fibres entre toute paire donnée de noeuds sont incapables de prendre en charge tous les régimes de communication appropriés, lesdites liaisons sont modifiées pour permettre cette prise en charge.
