H BES (Bursty Errored Seconds): Contains the number of bursty errored
seconds for the current interval. A bursty errored second is any second with
more than one but less than 805 CRC errors (CRC Mode) or more than one
but less than 16 FAS errors (non-CRC mode).
H CSS (Controlled Slip Seconds): Seconds during which one or more
controlled slips (as defined in TR 54016) occurred.
H LOF (Loss of Frame Seconds): Contains the number of seconds that
contain one or more LOF events.
H Status: Contains the contents of the status events register. The status events
register maintains a history of specific events that have occurred during an
interval. Values include:
— Y: Remote alarm indication signal received at the G.703 interface
— L: Loss of signal detected at the G.703 interface
— E: Excessive error rate threshold exceeded
— F: Frame synchronization bit error detected
— V: Line code violation detected
— None: No significant events have occurred
