Abstract

L'invention concerne un procédé de détection d'un port de terminal de ligne optique (OLT). Le procédé comprend les étapes suivantes : un récepteur d'informations accède à un port devant être détecté ; un système de gestion de réseau donne pour consigne à un terminal de ligne optique (OLT) d'émettre des informations d'identification ; et le récepteur d'informations reçoit les informations d'identification envoyées par l'OLT par l'intermédiaire d'un dispositif de génération optique en ligne. La solution de l'invention permet de connaître rapidement des informations relatives à un port de maintenance, qui sont sans rapport avec un service, sans qu'il soit nécessaire de modifier le protocole PON, ce qui rend la maintenance plus simple et plus pratique et permet d'améliorer l'efficacité de la maintenance.
