VDSL Configuration

VDSL Performance Monitor Information

This screen displays line and channel performance data information since the switch was last reset, during the current 15 minute interval, and during the current day.

Command Attributes

•Line – Select the VDSL line from the drop-down list.

•Channel – Select Slow or Fast from the drop-down menu. The switch uses the slow channel for data that requires a very low error rate in transmission. The switch uses the fast channel for data such as voice/video signals that require fast delivery, but for which a small error rate is acceptable

•Side – This only displays Local. All information displayed is for data transmission from the switch to the CPE.

•Line Performance Data Information

-Loss of Frame (LOF) – Number of seconds that there was loss of framing, since the switch was last reset, or in the indicated time interval.

-Loss of Signal (LOS) – Number of seconds that there was loss of signal, since the switch was last reset, or in the indicated time interval.

-Loss of Power – Number of seconds that there was loss of power, since the switch was last reset, or in the indicated time interval.

-Loss of Link – Number of seconds that there was loss of link, since the switch was last reset, or in the indicated time interval.

-Errored Second – Number of Errored Seconds since the switch was last reset, or in the indicated time interval. An Errored Second is a one-second interval containing one or more CRC anomalies, or one or more LOS or LOF defects.

-Severely Errored Second – Number of Severely Errored Seconds since the switch was last reset, or in the indicated time interval. An Errored Second is a one-second interval containing one or more CRC anomalies, or one or more LOS or LOF defects.

-Unavailable Second – Number of Unavailable Seconds since the switch was last reset, or in the indicated time interval.

-Init – Number of line initialization attempts since the switch was last reset, or in the indicated time interval. This count includes both successful and failed attempts.

-Valid intervals – The number of intervals within which no errors have been detected.

-Invalid Intervals – The number of intervals within which errors have been detected.

•Channel Performance Data Information

-Current Time Elapsed – The time elapsed in minutes.

-Current Fixed Octet – The number of corrected octets.

-Current Bad Block – The number of uncorrectable blocks.

-Current Valid Interval – The number of intervals within which no errors have been detected.

-Current invalid Interval – The number of intervals within which errors have been detected.
