Result Description
NE Verdict Near End Verdict. Test status for the receive direction.
“Accepted” indicates that the test results have met the ITU-T Rec.
G.826 performance objectives.
“Rejected” indicates that the test results did not meet the perfor-
mance objectives.
NE AS Near End Available Seconds. A count of the number of Test Sec-
onds which met the ITU-T Rec. G.821 definition of available time.
NE ES Near End Errored Seconds. The number of available seconds
during which one or more relevant anomalies or defects were
present.
NE ESR Near End Errored Seconds Ratio. The ratio errored seconds to
the number of available seconds.
NE SES Near End Severely Errored Seconds. Available seconds during
which one or more defects were present or the anomaly block
error rate exceeded the ITU-T Rec. G.826 threshold.
NE SESR Near End Severely Errored Seconds Ratio. The ratio of Severely
Errored Seconds to the number of Available Seconds.
NE UAS Near End Unavailable Seconds. A count of the number of test
seconds which met the ITU-T Rec. G.826 definition of unavailable
time.
FE Verdict Far End Verdict. Test status for the send direction.
“Accepted” indicates that the test results have met the ITU-T Rec.
