DSL Error Stats

B-B-F

 

 

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 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 bucket updated every hour). A margin of 0 db equals an expected bit error rate of 10-7. (The higher the margins, the fewer the errors.)

The counters increment in real time and you may enter Ctrl-r at any time to reset the counters.

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-B.

dn err secs ± Count of the number of down error seconds with at least one block error in the downstream data path.

up err secs± Count of the number of up error seconds with at least one block error in the upstream data path.

dn svr err sec ± Count of the number of seconds with at least 800 block errors in the downstream data path.

up svr err sec ± Count of the number of seconds with at least 800 block errors in the upstream data path.

DSL Xmit Status (DSL Transmit Stats)

B-B-G

 

 

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 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 updated every hour).

The counters increment in real time and you may enter Ctrl-r at any time to reset the counters.

Port # ± Enter the port number (1 to 4) you wish to monitor.

dn xmit pwr ± Measure of the power level of the downstream signal sent to the SN (in db).

up xmit pwr ± Measure of the power level of the upstream signal sent by the SN (in db).

dn rx gain ± Measure of how much amplification was applied to the signal received at the SN.

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.
