Field Attributes
Basic Performance Counters
• LOF – Loss of Frame. The number of times there was loss of framing error.
• SES – Severely Errored Seconds. The number of second intervals containing 18
or more CRC-8 anomalies, one or more Loss of Signal (LOS) defects, one or more
Severely Errored Frame (SEF) defects, or one or more Loss of Power (LPR)
defects.
• ESE – Excessive Severe Errors. The number of times there were excessive severe
errors.
• LOS – Loss of Signal. The number of times there was a loss of signal error.
• RDI – Remote Defect Indication. The number of times a severely errored frame has
been detected at the far end.
• LOM – Loss of Margin. The number of times there was a loss of noise margin error.
• PO – Power Off failure count. (This parameter only applies to the far end.)
• ES – Errored Seconds. The number of second intervals during which there was
one or more CRC anomalies, or one or more Loss of Signal (LOS) or Loss of
Framing (LOF) defects
• UNAVL_ES – Unavailable Errored Seconds. The number of seconds during which
the VDSL transceiver is powered up but not available.

or more CRC-8 anomalies, one or more Loss of Signal (LOS) defects, one or more
