| Carte d'état des circuits dans les systèmes H.323 |
 |
La présente Recommandation spécifie un mécanisme qui permet à une passerelle RTPC - H.323 d'informer un portier sur l'état du service et de l'utilisation des circuits au moyen du paramètre "carte d'état des circuits". Les réseaux RTPC individuels utilisant la passerelle peuvent être mis hors service par une commande en ce sens émanant du personnel de service ou par la réception d'un message ISUP de mise hors service ou de blocage provenant du commutateur RTPC adjacent. Dans ce cas, la passerelle est en mesure d'informer le portier de l'état effectif des circuits afin qu'il puisse faire son choix parmi les circuits disponibles pour les appels sortants via cette passerelle. |
