Channel reliability

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


 * $$ChR = 100 (1 - \frac{T_o}{T_s} ) = 100 \frac{T_a}{T_s} $$

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.
