In telecommunications, 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 <sub>o</sub> is the channel total outage time, T <sub>s</sub> is the channel total scheduled time, and T <sub>a</sub> is the channel total available time.
