Description
DSX-1 Port
Errored Seconds
(ES) 24 Hour
Count
The number of one second intervals in which at least one bipolar
violation (BPV) or one CRC-6 error was detected at the DSX-1 input
port during the last 24hours.
Severely Errored
Seconds (SES)
24 Hour Count
The number of one second intervals during which a Loss of Signal
(LOS), an Alarm Indication Signal (AIS), or a Loss of Frame (or CRC-6
Multiframe) Alignment (LFA) occurred at the incoming port.
Unavailable
Seconds (UAS)
24 Hour Count
The number of seconds that DSX-1 input signals were unavailable
during the last 24 hours. After ten consecutive SESs, the system is
deemed unavailable, and the current UAS counter begins counting
from ten. After ten consecutive non-SESs, the system returns to
availability, and the ten counts representing the non-SESs are
removed from the UAS counter.
Bipolar Violation
Seconds
(Cumulative)
The number of seconds in which bipolar violations were detected at
the DSX-1 port since error counters were last cleared.
