That's what I am thinking and I told Pulse8 exactly that as well I suspect the master socket with the blanking plate is live and working but the socket which everything plugs into is dead or the cable which connects them both together..
Will try and get a phone to test it and I am tempted to remove the NTE5 plate from the new socket and put it back onto the old master socket and try plugging the router into that and see if it then works.
I am guessing this should be possible?
At the very least if I can get a phone I can plug it into both the test socket and the new socket to see which one has a dial tone etc.
But despite all of the above BT should of tested the new socket fully and if they had of done they would of seen the DSL was not working.
