| Mapas de circuitos en sistemas H.323 |
 |
Esta Recomendación especifica un mecanismo que permite a una pasarela de RTPC H.323 informar a un controlador de acceso sobre el estado de los circuitos mediante el parámetro mapa del estado de circuito. Se pueden poner fuera de servicio los circuitos RTPC de la pasarela mediante una instrucción de alta/baja del personal de servicio o al recibir un mensaje PU-RDSI de fuera de servicio o de bloqueo de la central RTPC adyacente. Entonces, la pasarela puede informar al controlador de acceso sobre el estado actual de los circuitos de forma que al procesar las llamadas salientes a través de la pasarela éste elija un circuito solamente entre los disponibles. |
