Channel reliability

In telecommunication, channel reliability (ChR) is the percentage of time a channel was available for use in a specified period of scheduled availability.

Note 1: Channel reliability is given by 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.

Note 2: T s = T a + T o.
