| Схемы соединений в системах H.323 |
В данной Рекомендации определяется механизм, который позволяет шлюзу H.323 КТСОП сообщать об обслуживании схемы и состоянии использования гейткиперу, используя параметр карты состояния схемы. Индивидуальные схемы КТСОП на шлюзе могут считаться вышедшими из эксплуатации при подаче команд от обслуживающего персонала или когда система ISUP вышла из строя, или когда от смежного коммутатора КТСОП получено блокирующее сообщение. В этом случае шлюз будет способен сообщать о текущем состоянии схемы гейткиперу так, чтобы он мог осуществлять выбор только из доступных схем для исходящих вызовов через этот шлюз. |
