I 100% have two.
One in the living room which is not working which go outside up along the side of the house to the line then to the telegraph pole.
The working one next to the front door which go into the dividing wall between myself and my neighbours then outside up the wall to the telegraph pole.
what I would expect is the outside line conencted to terminals A&B on the master socket then 2 wires from terminals 2&5 on the master detachable faceplate then conencted to terminals 2&5 in your extension socket
this may help http://www.kitz.co.uk/adsl/socket.htm
Ok I see. I only have wires going to A&B but nothing on the front plate in 5,3,2. It still seems I have two master sockets.
Here is the image of the front plate. https://www.dropbox.com/s/mlvu1swniyk23nm/2014-05-22%2015.08.48.jpg
but I have no extension boxs to where 532 would go to.
you should not have 2 master sockets on same line do both test sockets work?
As previously said the one in the living room doesn't work but the one next to the front door works, which is where the router is plugged into the test socket.
as there does not appear to be any wires conencted to front of master in hall have you any idea where the wires connected to the livingroom socket go/come from?
Yes, it go directly out side up along the side of the house meet up with the wires from the front door master socket and both wires go to where the telephone pole connects to the house.
ok so could that have been a totally separate phoneline and has nothing to do with the other master in the hall? hence why it no longer works
