Hi John,
Thanks for commenting, I was considering UPBO, but I don't think I have any control over that with the HG612.
I am more or less there for the low sidec estimate at 7.1 - 7.6Mbps, but quite far from the high at 11.2-11.4Mbps.

Line quality / cross talk I can accept, its the nature of the technology - I am just doing due diligence to make sure its not something I can make a difference to.

So maybe some specific interference in the    1972 -2782 tones (8.5 - 12 MHz)?

and it looks like I am picking up Kiss FM (harmonic?) in the middle of that tone band, might explain why the DSLAM does not want to use that frequency range
