| معلمات أجهزة الوقاية من التموّر القائمة على التايرستور لحماية منشآت الاتصالات |
تعرف التوصية ITU-T K.28 المعلمات ودارات الاختبار وقيم الأداء لأجهزة الوقاية من التموّر القائمة على استخدام الثايرستور لحماية منشآت الاتصالات (مثل أجهزة التبادل وأجهزة النفاذ وخطوط الاتصالات وأجهزة العميل أو المشترك).
وينبغي استعمال هذه التوصية لمواءمة المواصفات الحالية أو المستقبلية التي يصدرها مصنعو أجهزة الوقاية من التموّر القائمة على استخدام الثايرستور أو مصنعو معدات الاتصالات أو الإدارات أو مشغلو الشبكات. |
