Abstract

L'invention porte sur une technique de commande des équipements des noeuds d'un système de transmission en anneau du type réseau optique synchrone (SONET). Des signaux de commande provenant d'un centre de commande sont transmis, dans un octet sélectionné de la trame SONET, vers chacun des noeuds (50-57) raccordés à l'anneau SONET (24). Chacun des noeuds du réseau SONNET comporte un décodeur (61) de signaux de commande pour ce qui concerne l'adresse de destination, et si l'élément correspondant est trouvé, le noeud décode un champ d'instructions pour exécuter les fonctions représentatives. L'instruction peut être d'activer ou de désactiver les circuits du noeud, ou de recevoir ou d'émettre des signaux vidéo sur des canaux de transmission vidéo donnés de la trame SONET. On peut ainsi connecter ou déconnecter les équipements des différents noeuds de manière à optimiser l'utilisation de la bande passante du réseau SONNET.
