Abstract

On utilise des données numériques dans des paquets protégés contre les erreurs pour moduler une porteuse puis on inscrit cette porteuse modulée sur un réseau de distribution de données numériques aux fins d'émission vers un récepteur sur un trajet de transmission. Afin de surveiller le fonctionnement du réseau de distribution de données, on introduit des anomalies sur une certaine étendue en amont d'un segment du trajet de transmission à tester puis on envoie au récepteur un paquet de données protégé contre les erreurs. Une vérification est faite au niveau du receveur afin de déterminer si le paquet de données reçu est exempt d'erreur et, si ce n'est pas le cas, le récepteur envoie un message à l'émetteur.
