| Protocole de commande de passerelle: paquetages de ligne analogique améliorée |
 |
La présente Recommandation définit plusieurs paquetages pour la Rec. UIT-T H.248, qui prennent en charge une supervision étendue de ligne et des capacités de taxation pour les lignes analogiques. La présente version vise à ajouter un signal de production des impulsions de taxation par phase, susceptible d'être employé dans des scénarios de taxation complexes, dans lesquels les capacités des signaux de comptage dépassent celles déjà assurées par le paquetage. Il vise aussi à introduire un nouveau paquetage, permettant aux passerelles média de détecter les impulsions de taxation, et à mettre à jour l'ensemble des paquetages dans la présente Recommandation afin qu'ils soient conformes au nouveau modèle de paquetage. |
