This report shows xDSL status indicators.
Near-End CRC Last
Number of seconds of cyclic redundancy check error 
counts.
Near-End CRC Last
Number of minutes of cyclic redundancy check error 
counts.
Failure Counters Overall
Total overall failure frames.
Local SEF
Count of local (near-end) severely errored frames.
Local LOS
Count of local (near-end) loss of signal frames.
Remote SEF
Count of remote (far-end) severely errored frames.
Remote LOS
Count of remote (far-end) loss of signal frames.
ADSL Standard
