Abstract

Dispositif d’accès, système de gestion et méthode pour les utiliser. Le système comprend un module de rapport d’information d’état d’alimentation du dispositif établi dans le dispositif d’accès et raccordé à la source électrique du dispositif d’accès pour surveiller l’état de l’alimentation du dispositif d’accès. Lorsque le module surveille un changement d’alimentation, il établit des informations d’état d’alimentation du dispositif et les rapporte au module de gestion d’état du dispositif. Le module de gestion d’état du dispositif est établi dans la gestion de réseau pour gérer l’état du dispositif d’accès en fonction desdites informations d’état d’alimentation du dispositif. En utilisant lesdits système et méthode de l’invention, lorsque les informations de communication sont interrompues entre la gestion de réseau et le dispositif d’accès de bord optique, la gestion de réseau peut juger précisément si l’interruption est causée par l’endommagement du dispositif d’accès de bord optique/de la fibre optique ou si l’alimentation du dispositif d’accès de bord optique est interrompue. Ils peuvent ainsi largement réduire la charge de travail et les coûts de fonctionnement, de gestion et de maintenance du réseau de transmission optique.
