DSL Link Perf (DSL Link Performance Summary) B-B-D
Displays a summary of the link performance for each of the DSL ports.
Enter port number 1–4 to see the fields for current 15-minute period (real time count of
events during the past 0 to 15 minutes), previous 15-minute period (data updated every
15 minutes), previous 1-hour period (data updated every hour), and 24-hour period (data
is updated every hour).
Port # : – Enter the port number (1–4) you wish to monitor.
Dn Margin – Measure of the noise margin on the specified port in the downstream
direction. A positive margin number reflects a lower error rate with a higher tolerance.
Up Margin – Measure of the noise margin on the specified port in the upstream
direction. A positive margin number reflects a lower error rate with a higher tolerance.
DnErrRate – This statistic is not available for this release and 0 (zero) appears for each
time period.
UpErrRate – Block error rate in the upstream direction. Error rate = bad blocks/good
blocks and is expressed as A x 10
-B
.
DnAttEst – Measure of the downstream transmission loss on the DSL line.
UpAttEst – Measure of the upstream transmission loss on the DSL line.
link dn count – Number of times the DSL link has gone down.
elp lnk up – Count of the elapsed time in seconds that the link has been up.
elp time – Count of the elapsed time in seconds since the DSL card was last reset.
