CA 2387750

A method for diverting traffic transmitted between a first location and a second location, to be transmitted over protection links, which method comprises: detecting a fault on a first optical link at the second location; if the energy received over the reception optical link at the second location does not exceed a pre- defined threshold, diverting the traffic transmission and reception at the second location to the corresponding protection links; detecting a fault on a first optical link at the first location; if the energy received via the first optical link at the first location does not exceed a pre-defined threshold, diverting the traffic transmission and reception at the first location to the corresponding protection links.

La présente invention concerne un procédé destiné à dériver un trafic émis entre un premier emplacement et un second emplacement, à émettre sur des liaisons de sécurisation, qui consiste à détecter un défaut sur une première liaison optique au second emplacement, à dériver l'émission et réception de trafic au second emplacement vers les liaisons de sécurisation correspondantes si l'énergie reçue via la liaison optique de réception au second emplacement n'excède pas un seuil prédéterminé, à détecter un défaut sur une première liaison optique au premier emplacement, et à dériver l'émission et réception de trafic au premier emplacement vers les liaisons de sécurisation correspondantes si l'énergie reçue via la liaison optique de réception au premier emplacement n'excède pas un seuil prédéterminé.
