Abstract

A method of determining an error level of a data channel comprised of (a) receiving channel parity error data indicating when bit errors occur within a set of data carried on the channel (channel error events), successively integrating the channel error events data over successive accumulation periods, comparing the integrated channel error events data with a threshold, and indicating an alarm in the event the integrated channel error events data exceeds the threshold.
