Thanks for the diagram, it gives me a better understanding of how you got your BW upto 6Mb
FP did a truck roll and the tech came in a did some testing copper line measurement from inside and ourside of the house to the DSLAM.
He identified some wiring in my house that could be improved and after some quick re-wiring, my SNR and line attenuation are better.
Here are the new XVR stats:
Transceiver Information Down Stream Path/ Up Stream Path
DSL Speed (Kbits/Sec) 3360/ 864
Margin (dB) 28.8/ 17.0
Line Attenuation (dB) 19.1/ 8.0
Transmit Power (dBm) 5.8/ 11.9
here are the before re-wiring numbers restated for reference
DSL Speed (Kbits/Sec) 3360 /864
Margin (dB) 27.5 /9.0
Line Attenuation (dB) 28.8 /11.5
Transmit Power (dBm) 6.6 /11.9
Speedtest remains the same, a good ~3Mbps up, 0.7Mbps dn
It is worth noting that the uplink problem that got this thread started did not exist with the older/noisier wiring and that the fix last night was done without any rewiring - something upstream of the DSLAM. However I am glad the FP tech came and improved the SNR.
