Abstract
Error rates above a given threshold are detected by initiating a counter to count a group of n bits on each occurrence of an error bit. The counters are inspected on each occurrence of an error to see whether the counter initiated x error bits earlier is still counting. If the counter is still counting the error rate is above a threshold of x error bits in a group of n bits in a serial stream.
