I was wondering how these line tests actually work? The type you put in your number and it works away for a while and then comes back with a range of what bandwidth you should be able to get? Are they generally accurate?
When I run mine, I am currently in ADSL how can it give me a figure for both adsl and vdsl if moving to VDSL involves being hooked up to a different cabinet?
Does it perform two separate tests, one between me and the exhange (my current connection) and another between the fibre cab and me?
