Range Extended ADSL

Does anyone know anything about Range Extended ADSL (RE-ADSL) for rural areas far from the exchange ?

Re: Range Extended ADSL

RE-ADSL, or ADSL2 Annex L (not ADSL2+) is not supported in the UK.
http://en.wikipedia.org/wiki/G.992.3_Annex_L
Due to the cross-talk it can introduce, it is (or at least wasn't as of September 2011) not licensed under the ANFP (Access Network Frequency Plan)

Re: Range Extended ADSL

Hi Phil
Thanks for the reply which sounds like I am on the right track.  To be fair, this has nothing to do with my Plusnet account at all - I wish it did !  I have a house in France where I pay four times as much in rental for my broadband as I do with Plusnet in the UK for a lousy, unreliable 512 kb service, and if anything goes wrong, I just get the usual "Gallic shrug" and  verbal "Prrr." !  Not even the dear old GPO Telephone was ever as bad in terms of customer service, but then France Telecom is of course a good old state monopoly and have no real competition.  So much for my problems !
Now, I live in a very rural community in the UK, a couple of miles from the exchange but get about 6Mb download speed with Plusnet.  In France, I live in an identical environment but I have only just discovered that I receive Range Extended ADSL which may explain a lot of things.  The internet is always falling out.  I listen to UK radio using a dedicated Internet Radio (not on the computer), and the BBC is always dropping out.  VOIP and Skype are painful while landline telephone rates are of course prohibitively expensive - it is actually cheaper to use my UK Virgin mobile phone despite the roaming charges, but only if I can get a signal !  And one of the major problems I face is that, while I can control the central heating remotely using a DTMF tele-switch, I regularly get a "fax hand-shake" tone interrupting the call to the tele-switch which stops it connecting.
In view of what you say about "cross-over" I wonder whether at last I have found the explanation for this "fax handshake" ?  Could the RE-ADSL be the cause by any chance ?  I would be grateful for your opinion and for your thoughts on the various other problems which I have mentioned.
