Configuring the Switch

Monitoring VDSL Performance History

This page displays line and channel performance data information during selected 15 minute intervals over the last 24 hours of switch operation, and during selected 1-day intervals from the current day to 30 days ago.

Command Attributes

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

Channel – Select Slow or Fast from the drop-down list.

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

Line Performance Data History Information

For the 15 Min Interval column, interval 1 is the most recent interval; interval 96 is 24 hours ago.

For the 1 Day Interval column, interval 1 is the most recent day; interval 30 is 30 days ago.

-Loss of Frame (LOF) – Number of seconds that there was loss of framing in the indicated time interval.

-Loss of Signal (LOS) – Number of seconds that there was loss of signal in the indicated time interval.

-Loss of Power – Number of seconds that there was loss of power in the indicated time interval.

-Loss of Link – Number of seconds that there was loss of link in the indicated time interval.

-Errored Second – Number of errored seconds 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 in the indicated time interval. An errored second is a one-second interval containing one or more one or more CRC anomalies, or one or more LOS or LOF defects.

-Unavailable Second – Count of unavailable seconds in the indicated time interval.

-Init – Number of line initialization attempts in the indicated time interval. This count includes both successful and failed attempts.

Channel Performance Data History Information

-Fixed Octet – Number of corrected octets in the indicated time interval.

-Bad Block – Number of uncorrectable blocks in the indicated time interval.
