| بروتوكول التحكم بالبدالة: وصف شفرات الخطأ وأسباب تغيير الخدمة |
تحدد الرزم في التوصية ITU-T H.248.3 إطاراً لتحديد المقدرات المرتبطة بعناصر السطوح البينية للمستعمل، مثل شاشة عرض النص، والمفاتيح، والمفاتيح الموسومة دينامياً، والمؤشرات والدخل الألفبائي الرقمي. وعلاوة على ذلك، تم تحديد رزم تمديد معينة من أجل لوحة أرقام الهاتف ومفاتيح وظيفة الهاتف. وتشمل هذه المراجعة تصويب معلمتي "حالة" "State" إشارة مؤشر المجموعة و"وصف مؤشر" "Indicator description" لهذه الإشارة. ملاحظة - أُعيد ترقيم هذه التوصية التي كانت تشكل سابقاً الملحق G في التوصية ITU T H.248. |
