ABSTRACT:
Disclosed are various embodiments for outage detection. In one embodiment, an outage detection system includes a signal sampler configured to sample a signal on a communications link and to determine a noise level and a signal level of the sample. An outage detection system also includes a comparator configured to compare a critical value with a sum of signal and noise of the sample. An outage detection system further includes a binomial probability analyzer configured to calculate a binomial probability of false outage of the sample and the previous N samples.
