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.

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.

UAS The number of UnAvailable Seconds.that have occurred since the last

connection was established.

Segment

Anomaly

The number of Segment Anomalies that have occurred since the last

connection was established. A segment anomaly indicates that a regenerator

operating on a segment has received corrupted data and therefore the

regenerated data is unreliable.

Segment Defect The number of Segment Defects that have occurred since the last connection

was established. A segment defect indicates that a regenerator has lost SHDSL

synchronization and therefore the regenerated data is unavailable.

15 min, 1day history This section of the screen displays line performance statistics for the current

and previous 15-minute periods, as well as for the current and previous 24

hours.

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.

crc The number of CRC anomalies detected within the period.

es The number of Errored Seconds detected within the period.

ses The number of Severely Errored Seconds detected within the period.

losws The number of Loss of Sync Word Seconds detected within the period.

uas The number of UnAvailable Seconds detected within the period.
