Ripped out phone point

brizospark · Sep 17, 2013

Doing a rewire at the moment and the builder has ripped the main phone point right out wall leaving just the cable sticking out wall

In sure it is the main phone cable into the house as it is a thick black 4pair round flex like

Not had much to do with telephone points in the past apart from adding a point in here and there

Can anyone put me right on reconnecting this to get phone point working again

Many thanks

out of the 4 cores, only 2 are used for the line. this pair will have 48V D.C. on them. these go onto A and B, or 2 and 5. will work either way round, but i think the + is B.

Nice one. Just out of curiosity why do BT still run 4 pair in when they only effectively need one pair?

2 lines?

If I remember correctly from my BT days the 4 colours are black white green and orange, black and green are 1 pair and orange and white the other.on the master will be 2 connections A and B these are for the incoming wires,any extensions go to the IDC connectors on the front plate.
