I was in north London yesterday evening visiting a young friend in his new vicarage (he is the new vicar, the vicarage is c.1930s).
His father has been down there helping with the move and they've found various telephone wires and sockets all in a generally shambolic state and have managed to find one socket that works with a telephone for voice so temporarily have run an extension from there to his study to give broadband. Clearly unsatisfactory and slow but it does at least work.
His father tried to find which sockets were showing 50v across any pairs of wires and found most of them were not so showing. Is that a valid approach? I thought, possibly wrongly these days, that was the ring voltage not the quiescent state voltage.
Similarly he couldn't find any box that looked to be the master socket.
One of the problems is that they cannot trace where the telephone line comes into the house. Albeit in the dark I couldn't see any overhead wires or nearby telegraph poles so the assumption is that it is underground. Apparently there is a small cellar so that has to be investigated as a possibility, Also the attic should be checked - just in case.
Are there any web sites showing pictures of the various ways, and boxes, that a BT line enters a house? Robertos.me.ok and kitz.co.uk both have lots of useful information and pictures, though I couldn't see any of the possible external interfaces/boxes.
Clearly once they can find the point of entry tracing the internal boxes and wiring becomes a little easier.
Any suggestions, pictures, etc. of what to look for to track the point of entry would be appreciated.
