Abstract

La présente invention concerne un procédé pour surveiller les alertes de panne de la puce, qui comprend les étapes suivantes : (101) le côté d'envoi sur la puce du flux de trafic montant calcule une position de surcharge fixe lorsque les données d'envoi doivent être insérées et insère une valeur escomptée dans la position de la surcharge fixe, (102) le côté de réception sur la puce du flux de trafic descendant calcule une position de surcharge de veille fixe des données de réception, et extrait la valeur de la surcharge de veille fixe, (103) compare la valeur extraite de la position de la surcharge de veille fixe avec la valeur escomptée, (104) si la valeur extraite de la position de la surcharge de veille fixe diffère de la valeur escomptée, détermine qu'il existe une panne dans le canal du flux de circulation et déclenche la bascule de la carte correspondante. Le procédé de l'invention permet de surveiller l'état des puces dans le canal de transmission du flux de trafic de transmission en temps réel et donc de déclencher la commutation de la carte dans les temps et restaurer le trafic lorsque la puce est en panne.
