Someone decipher this text for me:
"The Master line box is the "demarcation" point between your telephone equipment, wiring and BT's Exchange Line.
The reason this is so, is that everything on your side of the master, is your problem. Everything on BT's side, including the Master line box itself, is BT's problem. It needs to stay this way!
Now if you want to something along the lines of; move the Master socket (to get rid of the crap wire between that junction box and master socket) or to relocate the Master socket to where the drop cable enters your premises, then to do this is YOUR choice, if you mess it up, then you will need BT to sort it out, IF they sort it out for you that is (keep reading).
If you successfully move your Master socket to have more high quality user-side wiring then good for you, but it is ILLEGAL to do this, if it is clear and obvious that you moved it yourself and BT issues a fine and/or terminate your line. Dont say you weren't warned.
That was the warning just in case you didnt understand the ILLEGAL part."http://www.rob-r.co.uk/other/UKphonecatwiring.htm
So is the above saying that to basically, play around with the ring wire is in fact illegal?
