Look at the profile name in the GEA test, if the speed is not the maximum for the product (e.g. 80Mbps or 40Mbps) then it is a banded profile.
I have also had experience of the GEA test result not being up to date, when I had a line fault earlier this year, the line was banded at a low speed and G.Inp applied on upstream, (normally downstream only). When I pointed this out to PlusNet on their forum, they claimed I was not banded. So the test is fairly useless for examining the current line conditions.
