Just wondering what would happen if one was to apply a 1000 volt insulation resistance test to the incoming phone line wires before the master socket.
I would hope the system has protection mechanisms built in and nothing would get damaged at the exchange end.
Not that I am going to try - certainly don't want to start WW3 with BT Openreach; just curious.
