LPR_FE: A far end Loss of power - LPR-FE failure is declared after the occurrence of a far end LPR
primitive followed by 2.5 +- 0.5 s of contiguous near end LOS defected. A far end LPR failure is
cleared after 10 +- 0.5 s of no near end LOS defected.
ES It means Error Seconds.
This parameter is a count of 1 second intervals with following factors:
one or more LPR defects
SES It means Severely Error Seconds. This parameter is a count of 1 second intervals with
CRC 8 anomalies summed over all received bearer channels and related definition refer to items 2~4
of "ES". If a common CRC is applied over multiple bearer channels, then each related CRC-8 anomaly
shall be counted only once for the whole set of bearer channels over which the CRC is applied.
UAS It means Unavailable Seconds.
This parameter is a count of 1 second intervals for which the XDSL line is unavailable. The XDSL line
becomes unavailable at the onset of 10 contiguous SES Ls. The 10 SESs are included in unavailable
time. Once unavailable, the XDSL line becomes available at the onset of 10 contiguous seconds with
no SESs. The 10 seconds with no SESs are excluded from unavailable time.
