Performance
(since last boot
up)
There is a mechanism in SHDSL for the STU-C and STU-R to
exchange information about line performance. As a result, the
SAM1316-22 can report the errors detected by the STU-C and the
STU-R.
Stuc: This refers to what is detected by the Central Office (CO) end
point.
Stur: This refers to what is detected by the Remote (R) end point.
Init
This field displays the number of link-ups and link-downs.
Stuc/Stur ES
The number of Errored Seconds detected by the STU-C and the STU-
R on this DSL port. An Errored Second is defined as a count of 1-
second intervals during which one or more CRC anomalies are
declared and/or one or more LOSW defects are declared.
Stuc/Stur SES
The number of Severely Errored Seconds detected by the STU-C and
the STU-R on this DSL port. A Severely Errored Second is defined as a
count of 1-second intervals during which at least 50 CRC anomalies
are declared or one or more LOSW defects are declared. (50 CRC
anomalies during a 1-second interval is equivalent to a 30% errored
frame rate for a nominal frame length.)
Stuc/Stur
CRCanomalies
The number of CRC anomalies detected by the STU-C and the STU-R
on this DSL port.
Stuc/Stur
LOSWS
The number of Loss of Sync Word Failure Seconds detected by the
STU-C and the STU-R on this DSL port.
Stuc/Stur UAS The number of UnAvailable Seconds.detected by the STU-C and the
STU-R on this DSL port. An Unavailable Second is a count of 1-second
intervals for which the SHDSL line is unavailable. The SHDSL line
becomes unavailable at the onset of 10 contiguous SESs. The 10
SESs are included in the unavailable time. Once unavailable, the
SHDSL line becomes available at the onset of 10 contiguous seconds
with no SESs. The 10 s with no SESs are excluded from unavailable
time.
Stuc/Stur
Segment
Anomaly
The number of Segment Anomalies that have occurred since the last
bootup. A segment anomaly indicates that a regenerator operating on
a segment has received corrupted data and therefore the regenerated
data is unreliable.
Stuc/Stur
Segment
Defect
The number of Segment Defects that have occurred since the last
bootup. A segment defect indicates that a regenerator has lost SHDSL
synchronization and therefore the regenerated data is unavailable.
Performance
(since last link
up)
ES
The number of Errored Seconds that have occurred since the last
connection was established.
SES
The number of Severely Errored Seconds that have occurred since the
last connection was established.
CRCanomalies
The number of CRC anomalies that have occurred since the last
connection was established.
LOSWS
The number of Loss of Sync Word Seconds that have occurred since
the last connection was established.
