DSL Error Stats Screen – Model 8365 B-B-F
Displays errors encountered on a selected port during the current 15-minute period, the
previous 15-minute period, the previous hour, and the current day.
Enter a port name (dsl1–dsl12) to see current statistics.
dn err secs, up err secs (Downstream and Upstream Errored Seconds) – The number of
errored seconds that have been encountered on the port. An errored second is a
1-second interval during which one or more of the following occurred: a Cyclic
Redundancy Check (CRC) error; Loss of Signal (LOS); Severely Errored Frame (SEF); or
Loss of Power (LOP).
dn svr err sec, up svr err secs (Downstream and Upstream Severely Errored Seconds)
– The number of Severely Errored Seconds (SESs) that have been encountered on the
port. An SES is a 1-second interval during which 18 or more of the following occurred:
a CRC error; LOS; SEF; or LOP.
dn unavail sec, up unavail sec (Upstream and Downstream Unavailable Seconds) –
The number of 1-second intervals during which the DSL line is unavailable. The line
becomes unavailable after 10 contiguous SESs. Once unavailable, it becomes available
again after 10 contiguous seconds that include no SES.
Link Down Count – The number of times the link has gone down.
SN loss of power – The number of LOPs reported. LOP is declared upon receipt of four
“dying gasp” messages from the remote unit.
Current Interval Counter – How much time has elapsed in the current 15-minute interval.
DSL Error Stats Screen – Model 8385 B-B-F
Displays errors encountered on a selected port during the current 15-minute period, the
previous 15-minute period, the previous hour, and the current day.
Enter a port name (dsl1–dsl24) to see current statistics.
dn err secs, up err secs (Downstream and Upstream Errored Seconds) – The number of
errored seconds that have been encountered on the port. An errored second is a
1-second interval during which one or more of the following occurred: a Cyclic
Redundancy Check (CRC) error or Loss of Sync Word (LOSW).
dn svr err sec, up svr err secs (Downstream and Upstream Severely Errored Seconds)
– The number of Severely Errored Seconds (SESs) that have been encountered on the
port. An SES is a 1-second interval during which 50 or more CRC errors or one or more
LOSW defects occurred.
dn unavail sec, up unavail sec (Upstream and Downstream Unavailable Seconds) –
The number of 1-second intervals during which the DSL line is unavailable. The line
becomes unavailable after 10 contiguous SESs. Once unavailable, it becomes available
again after 10 contiguous seconds that include no SES.
dn CRC Anomalies, up CRC Anomalies (Downstream and Upstream CRC Anomalies)
– The number of CRC anomalies that have occurred during the accumulation period.
dn LOSW sec, up LOSW sec (Downstream and Upstream Loss of Sync Word Seconds)
– The number of 1-second intervals during which one or more LOSW defects are declared
during the accumulation period.
Link Down Count – The number of times the link has gone down.
Current Interval Counter – How much time has elapsed in the current 15-minute interval.
