We had fibre internet installed about 6 months ago by the contractors for orange.fr.
It’s great – about 55 to 60 mbps down and 15 mbps up, copper lines were at best 10 down and less than 5 up.
We still have the pre-existing copper line telephonique wiring hanging about, we are not connected to it but it’s still there, swinging in the breeze across the house wall, courtesy of the previous brit owners of the house.
I want to get rid of it, if I meter the 2 wires in the old telephone socket with a digital multimeter and do not detect any voltage, is it ok to crop the wires off with a long reach pole pruner at the box on the wall about 7 metres high?
I recall the old UK dc voltage on phone lines was around 50 volts?
