Hi,

I wish to install BT telephone extension socket in our study. We
currently have one socket in the living room and one upstairs. I
haven't checked yet which is the Master.

Anyway, I want to do this by properly wiring it in.

So some questions:

1. I'm going to get a faceplate which has a built-in ADSL filter for
simplicity. Now, what sort of "box" do I need to sit behind this? I
presume I will have to cut into the wall if I want to mount this
without it sticking out a lot. What helps keep it in place once
installed? If I decide to just stick the box on the wall, what keeps
_that_ in place?

2. If the socket upstairs is an extension it will be easiest to run a
second extension from that. I'll chekc whether the existing one is
crimped or screwed. Either way, what's the best way of running the
wires? Some form of joining block? Will this joining block fit in
the box along with everything else?

Hmm, that's actually it for now, my Google searches have answered the
rest for me so far.

Thanks in advance,

Tris.
