I have just formally requested to change my VDSL profile from 8a to 17a through the Snap helpdesk.
But apparently Telecom are either declining the change for 99% of the requests, or even if they manage to get one through, the profile gets reset back automatically after a day or two back to 8a.
He mentioned something about the 'DLM'? not sure what it is, and he also mentioned that the DSLAMS need a firmware upgrade to accomodate this? This is at Telecoms discretion, and of course they are not wanting to move us to potential 100Mb speeds!
Has anyone else found this with any other ISP? Or is it a Telecom level thing?
Is anyone on profile 17a? If so what are your speeds/attenuation?
