DESCRIPTION
Click Flush to clear the counters.
These are the DSL line's current downstream and upstream signal to noise margins in
decibels.
These are the DSL line's current downstream and upstream line attenuation in
decibels.
These are the DSL line's current downstream and upstream output powers in
decibels.
These are the DSL line's current downstream and upstream attainable rates in
decibels.
These are the numbers of milliseconds of interleave delay for downstream and
upstream transmissions.
This field displays the level of impulse noise (burst) protection for a slow interleaved
channel.
These are the DSL line's current downstream and upstream transmission rates in
decibels.
These are the DSL line's previous downstream and upstream transmission rates in
decibels.
These are the DSL line's downstream and upstream numbers of seconds during which
at least one FEC (Forward Error Correction) event that have occurred since the
system last started up.
These are the DSL line's downstream and upstream numbers of Loss of frame
Seconds that have occurred since the system last started up.
These are the DSL line's downstream and upstream numbers of Loss of signal
Seconds that have occurred since the system last started up.
These are the DSL line's downstream and upstream numbers of Loss of link Seconds
that have occurred since the system last started up.
These are the DSL line's downstream and upstream numbers of 1-second intervals
containing one or more Loss Of Link (LOL) failures that have occurred since the
system last started up.
These are the DSL line's downstream and upstream numbers of Loss of power
Seconds that have occurred since the system last started up.
