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 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 current day, starting at 12:01 a.m. (data 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.)

You may press Ctrl-r at any time to reset counters.

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

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 (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) 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 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 current day, starting at 12:01 a.m. (data updated every hour).

You may press Ctrl-r at any time to reset counters.

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

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 RADSL 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.
