| متطلبات الاعتمادية لأنظمة الاتصالات التي تتأثر بإشعاع الجسيمات |
تصف التوصية ITU-T K.139 متطلبات الموثوقية لمعدات الاتصالات فيما يتعلق بالأخطاء العارضة التي تسببها إشعاعات الجسيمات. ويرد وصف مبادئ تحديد متطلبات الموثوقية ويرد تعريف ثلاثة أنواع من متطلبات الموثوقية (موثوقية وظيفة الإنذار وموثوقية الخدمة وموثوقية الصيانة). ويرد تعريف ثلاثة أصناف من الموثوقية لكل نوع من المتطلبات على أساس معدل أعطال الأخطاء العارضة المقبول. ويرد تحديد قيم محددة لكل نوع وصنف من متطلبات الموثوقية. |
