In non-BURST mode, an alarm state is entered if an error count exceeds a threshold within a set number of frames and exits the alarm state when the error count stays below a threshold for a set number of frames. In the BURST mode, the alarm state is not entered unless the error count exceeds the threshold two consecutive times and does not exit the alarm state unless the error rate remains below a threshold for two consecutive frame counts.Other References
