Английская Википедия:Channel reliability
Материал из Онлайн справочника
In telecommunication, channel reliability (ChR) is the percentage of time a communication channel was available for use in a specified period of scheduled availability.
Channel reliability is given by
- <math>ChR = 100 (1 - \frac{T_o}{T_s} ) = 100 \frac{T_a}{T_s} </math>
where T o is the channel total outage time, T s is the channel total scheduled time, and T a is the channel total available time.
