| السمة المشتركة لشبكة المعلومات الإضافية في أنظمة H.323 |
تصف هذه الخدمة الإضافية الإجراءات وبروتوكول التشوير من أجل ميزة الشبكة الإضافية للمعلومات المشتركة (ANF-CMN) في شبكات H.323 (أنظمة اتصالات الوسائط المتعددة القائمة على الرزم). وتمكن هذه الشبكة من تبادل المعلومات المشتركة بين النقاط الانتهائية في ANF-CMN. وهذه المعلومات المشتركة هي مجموعة من معلومات شتى تتصل بالمستعمل أو المعدات في طرف من التوصيل وتشمل معرفات الميزة وفئة الطرف، أو كلاهما.
وتستخدم هذه التوصية "البروتوكول الوظيفي النوعي لدعم الخدمات الإضافية في H.323" كما هو معرف في ITU-T H.450.1. |
