LABEL
DESCRIPTION
PerfDataEntry
This section displays current VDSL performance measured for the downstream (
Vtuc
) and upstream (
Vtur
)
directions.
Fecs (seconds)
This field displays the number of seconds at least one FEC (Forward Error Correction)
event occurred on this line.
Lofs (seconds)
This field displays the count of 1-second intervals containing one or more Loss of
Framing (LOF) failures.
Loss (seconds)
This field displays the count of 1-second intervals containing one or more Loss of
Signal (LOS) failures.
Lols (seconds)
This field displays the count of 1-second intervals containing one or more Loss Of Link
(LOL) failures and the number of times an LOL failure occurred.
Lprs (seconds)
This field displays the count of 1-second intervals containing one or more Loss Of
PoweR (LPR) failures and the number of times an LPR failure occurred.
Es (seconds)
This field displays the number of seconds the following events occurred on this line:
• the downstream: CRC-8, LOS, SEF or LPR value greater than or equal to 1 on the
line.
• the upstream: FEBE, LOS-FE, RDI or LPR-FE value greater than or equal to 1 on the
line.
Ses (seconds)
This field displays the number of seconds during this interval that:
• the downstream: LOS, SEF or LPR value was greater than or equal to 1 or the
number of CRC-8 anomalies greater than or equal to 18 times on the line.
• the upstream: LOS-FE, RDI or LPR-FE value was greater than or equal to 1 or the
number of FEBE anomalies greater than or equal to 18 times on the line.
Uas (seconds)
This field displays the count of 1-second intervals for which the line is unavailable.
Use this to define this line tolerance that allows a period of Unavailable Seconds
(UAS) before disconnecting the link. Refer to ITU-T G997.1 chapter 7.2.1.1.5 for more
detailed information.
ChanPerfDataEntry
This section displays current VDSL channel performance measured for the downstream (
Vtuc
) and upstream
(
Vtur
) directions.
CorrectedBlks
This field displays the numbers of corrected blocks for downstream and upstream
transmissions.
UnCorrectedBlks
This field displays the numbers of uncorrected blocks for downstream and upstream
transmissions.
CodeViolations
This field displays the number of code words containing one or more anomalies.
RtxCw
This field displays the number of RS (Reed-Solomon) codewords or DTUs (Data
Transfer Units) retransmitted through PhyR or G.INP retransmissions.
RtxCorrectedCw
This field displays the number of RS codewords or DTUs that have been corrected
through PhyR or G.INP retransmissions.
RtxUncorrectedCw
This field displays the number of RS codewords or DTUs that were not corrected
successfully through PhyR or G.INP retransmissions.
Leftrs (seconds)
This field displays the number of seconds during which the Error Free Throughput
went below the pre-configured threshold.
MinEftr (kbps)
This field displays the lowest value of the Error Free Throughput within the current
interval.
