  1. Интерфейс V5.2 1-16E1 facilities АТС Сеть доступа AN LE - Динамическое распределение - 1..3 С-каналов на один Е1 - Протоколы интерфейса: • Контроля и контроля трактов • PSTN протокол • Протокол назначения каналов • Протокол защиты С-канала • ISDN протокол - Аналоговые абоненты - Базовый доступ - Первичный доступ - Полупостоянные соединения

  2. Сравнение интерфейсов V5.1 и V5.2 V5.1 G.964 1 PSTN ISDN-BRA V5.2 G.965 1-16 PSTN ISDN-BRA ISDN-PRA Стандарт ITU Количество трактов Е1 Поддерживаемый сервис Концентрация Защита С-канала NO NO YES YES

  3. Процедура старта протокола V5.2 (1) AN LE SABME (protection) LE запускает все протоколы на основном тракте и протокол защиты на резервном тракте UA (protection) SABME (control) UA (control) SABME (PSTN) UA (PSTN) SABME (BCC) UA (BCC) Примечание: последовательность этих сообщений может меняться в зависимости от АТС SABME (link control) UA (link control) RESET SN COM RESET SN ACK CC [Request Variant and Interface ID] CC-ACK [Request Variant and Interface ID] CC [Variant and Interface ID] CC-ACK [Variant and Interface ID]

  4. Процедура старта протокола V5.2 (2) AN LE CC [Restart Request] CC-ACK [Restart Request] CC [Restart Acknowledge] CC-ACK [Restart Acknowledge] CC [Restart Acknowledge] Старт протокола V5.2 закончен CC-ACK [Restart Acknowledge] CC [Unblock all ports block request] CC-ACK [Unblock all ports block request] CC [Unblock all ports block acceptation] CC-ACK [Unblock all ports block acceptation] CC [Unblock all ports block complete] CC-ACK [Unblock all ports block complete] CC [Unblock all ports block complete] CC-ACK [Unblock all ports block complete] Абонентские порты разблокированы
