2nd phone line - main socket location

[licquorice]

The drop wire is the cable from the pole to your house. It depends if it is physically possible to run it to where you want the master socket. It is also possible that the existing cable has a spare pair in it which the engineer would use rather than running a second cable.

Ok thanks for clarifying what a drop line is.

The existing drop line runs outside the house and actually past the office where I would like the new master socket.

Assuming the existing line has a spare pair would they use a junction box so they can take a branch off so we can have the master socket where it is needed?
