PerfCurr15Min
This section displays current VDSL performance measured for the downstream ( Vtuc ) and upstream ( Vtur )
directions.
TimeElapsed
This field displays the time since the last 15-minute data collection.
MoniteredTime These are the DSL line’s downstream and upstream lengths of time the system has
collected the line performance data in this current 15-minute time period.
Fecs (seconds) These are the DSL line’s downstream and upstream numbers of Forward Error
Correction Seconds (FECS) that have occurred for the past 15 minute period.
Lofs (seconds) These are the DSL line’s downstream and upstream numbers of Loss of frame
Seconds that have occurred for the past 15 minute period.
Loss (seconds) These are the DSL line’s downstream and upstream numbers of Loss of signal
Seconds that have occurred for the past 15 minute period.
Lols (seconds) This is the DSL line’s downstream number of Loss of link Seconds that have occurred
for the past 15 minute period.
Lol This is the number of times the DSL line’s downstream connection has experienced a
Loss of link during the past 15 minute period.
Lprs (seconds) This is the DSL line’s upstream number of Loss of power Seconds that have occurred
for the past 15 minute period.
Lpr This is the number of times the DSL line’s upstream connection has experienced a
Loss of power during the past 15 minute period.
Es (seconds) These are the DSL line’s downstream and upstream numbers of Errored Seconds that
have occurred for the past 15 minute period.
Ses (seconds) These are the DSL line’s downstream and upstream numbers of Severely Errored
Seconds that have occurred for the past 15 minute period. This is how many seconds
contained 30% or more errored blocks or at least one defect. This is a subset of Es.
Uas These are the DSL line’s downstream and upstream numbers of UnAvailable Seconds
that have occurred for the past 15 minute period.
FulInit These are the DSL line’s downstream and upstream numbers of successful
initialization traps that have occurred for the past 15 minute period.
