DSL Error Stats | |
|
|
Displays the error performance (margin) rates for each of the DSL ports after selecting a specific DSL port number. Margin is a measure of performance.
Enter port number one to four to see the fields for current

Error Rate Definition:
dn margin ± Measure of the noise margin on the specified port in the downstream direction.
up margin ± Measure of the noise margin on the specified port in the upstream direction.
dn err rate ± This statistic is not available for this release and an NA appears for each time period.
up err rate ± Block error rate in upstream direction. Error rate = bad blocks/good blocks and is expressed as A x 10
dn err secs (dn err mins for Model 8540) ± Count of the number of down error seconds with at least one block error.
up err secs ± (up err mins for Model 8540) ± Count of the number of up error seconds with at least one block error.
dn svr err sec ± This statistic is not available for this release and an NA appears for each time period.
up svr err sec ± Count of the number of seconds with at least 800 block errors.
DSL Xmit Status (DSL Transmit Stats) | |
|
|
Displays the transmit and receive statistics for each of the DSL ports after selecting a specific DSL port number.
Enter port number one to four to see the fields for current
You may enter
dn xmit pwr ± Measure of the power level of the downstream signal sent to the RTU (in db).
up xmit pwr ± Measure of the power level of the upstream signal sent to the RTU (in db).
dn rx gain ± Measure of how much amplification was applied to the signal received at the RTU.
up rx gain ± Measure of how much amplification was applied to the signal received at the DSLAM port.
dn att est ± Measure of the downstream transmission loss on the DSL line.
up att est ± Measure of the upstream transmission loss on the DSL line.
