Transfert des signaux de modems sur les systèmes H.323 |
|
La présente annexe définit les procédures de signalisation destinées à faciliter le transfert des signaux de modems sur les réseaux H.323, y compris l'indication de capacités et les procédures spécifiques d'ouverture et de fermeture de canaux prenant en charge le transport de signaux de modems sur les réseaux à protocole Internet (IP). Les signaux de modems peuvent être transmis sur des réseaux de type paquets au moyen d'un canal de transmission de données en bande vocale ou d'un canal relais pour modem. |
