"Paul" wrote in message I'm in the same
situation. I had broadband set up and no change was
made to the old GPO box I have. I rang BT and asked if they would
replace it with a plugin style master socket and I think the cost was
some way over £150 ! Bit reluctant to fiddle with the old box as there
are fragile wires all stuffed in and I'm sure I'd never get them back
in the right place (though if anyone can direct me to a wiring diagram
I guess that might help?)
