I think you may have misunderstood what he wants. Its not anything specific with ADSL2+ but applies to all xDSL technology. :/
Basically he wants you to be able to identify from a simple hlog graph where there may be some slightly non perfect piece of copper/joint or miniscule defect on his line and what point.
Whilst someone with a trained eye may be able to see that there may for example be a bridge tap and even give an approximate length of the bridge tap from hlog. What it is impossible to determine from a single 2 dimensional graph, is where the problem is in the network.
His claim is that someone will
be able to figure this out.. despite numerous technical documentation saying it isn't. Basically what he wants is the equivalent of a JDSU which can take several readings to build up an array of data, which then uses various algorithms to determine at what distance say the bridge tap occurs - this is not the same as length.
What he wants is possible if he goes out an buys a JDSU or similar and attaches it to his line. However, he refuses to spend money on one, so expects someone to be able to diagnose this from simple hlog provided by his router. B*cat has already coded something which allows him to plot the cartesian co-ordinates, but he is now wanting moon on a stick to do something which is patented technology (for free!) so he can run it on his line.
For example there is one such patent here which explains and does exactly what he wants. -linky to US Patent
If by any chance someone was ever prepared to do this, then just what he would do with this info I've no idea, because his Telco won't do anything about it.
FYI. Within the past week or so, he has been banned from 2 other forums (besides mine) that I know of. Thats not including the various other forums where he can no longer post or they also locked his threads/deleted his posts over the years. I'm quite honoured that he's only bitching about mine despite all the help he has been given.
