Line Status

Line Status

Operators can view extensive details about DSL line characteristics from the CLI, Port Monitor web page, or SNMP.

To view line characteristics using the webUI, click on DSL Monitor, then click the + sign to expand the port you wish to view.

Using the Port Monitor web page, the operator can quickly scan the status of all ports in the system. A color coded grid indicates the important status of each port e.g. GREEN indicates the Ethernet port is connected, whereas GREY indicates the port is enabled, but disconnected.

Per line details visible:

Status

Options are self-explanatory: disabled, enabled, linking, link lost, linked.

Quality

Link quality is a measurement of bit errors per second. Options are: Good, Fair, Bad. T3

 

includes Forward Error Correction in the VDSL frames. Bit errors that are not corrected are

 

counted and reported as a Line Quality measurement.

 

Bit errors of 0 – 0.51 per second = Good

 

Bit errors of 0.51 - 1 per second = Fair

 

Bit errors of greater than 1 per second = Bad

Portx

Where “x” is the number of a remote Ethernet port on the WallPlate. Shows the status of the

 

remote Ethernet port. Options are: connected, disconnected, disabled.

Downstream

Displays the line bitrate in the downstream direction in Mbits/second.

Upstream

Displays the line bitrate in the upstream direction in Mbits/second.

SNR DSx

Where “x” is 1 or 2. T3 uses a 4-band QAM modulation. Three of the 4 bands are used by T3

SNR USx

to maximize downstream line bitrate. DS1 and DS2 refer to the two downstream bands;

 

whereas US1 refers to the single upstream band. If a band shows 0 SNR, the band is not

 

being used by that line. During normal operation, it will be common to see 0 SNR on DS2.

 

US2 will always show 0, this is normal. SNR can be used to diagnose line issues, but must be

 

considered in concert with other parameters. Values are in dB.

Margin DSx

Each band requires SNR to be reserved as for margin. Typical values of SNR margin is

Margin USx

between 6 and 9. If margin is lower than 6, the line may have low quality and may retrain at

 

any time. If margin is greater than 9, the line is capable of a higher bitrate. Any band that is

 

not being used will show a margin of 0. Values are in dB.

Distance (m)

Distance value shows estimated line length in meters, based on the level of the attenuated

 

signal. Distance is accurate within 10% over 150m. Measurements below 150m are

 

displayed at <150.
