Hello all,
My first post here! I did a search but couldn't find an exact
answer...

I have two phone lines, I had one disconnected some months ago and
would now like to connect that linebox (2nd bedroom) to the still
connected line, using the neatly concealed BT cabling.

The external phone line coming into the house has 4 wires;
1. solid orange and white.
2. solid green and black.

At the point of entry to the first (master?) linebox the solid green
and black wires are screwed to A&B.

The the solid orange wire is connected with this small plastic tab to a
blue/white wire and the solid white wire is connected using the same
method to a white/blue wire.

In the second bedroom the linebox has the blue/white / white/blue
screwed to the A&B.

Do I cut the little plastic tabs in the first linebox, leave the solid
orange and white unconnected and then wire the blue/white / white blue
to terminal 2 and 5,

If the 'first linebox' is the one that still has a dialtone, yes.

then unscrew the blue/white / white blue from the
A&B on the 2nd box and connect to 2 & 5?

Unnecessary, A&B *are* 2&5, although technically you should use a
secondary socket at that point.

How can I tell which is the phone line that is still in use green &
black or White and orange?

The one that still has a dialtone?


One question. Does the cable to the 2nd linebox (white/blue) have an
extra cable pair available? (ie are there orange/white and green/white
wires spare at both ends).

If it does you can use these to connect 2,3,4,5 to the first linebox
then to a secondary socket in place of the second linebox (cutting the
non-functioning line as you said).


*Serious disclaimer*
BT don't often physically disconnect wiring at the exchange, they
probably just punched buttons on a computer, which means that 2nd
socket is technically still connected to their network, and it's a
criminal offense to mess with it.

If that cable between the 2 has 6 cores, you can use the orange/white
and green/white wires, a secondary socket right next to the 2nd
linebox, and not actually mess with the 2nd linebox electrically at
all.

UK.Telecom has a few current BT engineers and a *lot* of people with
experience of what is and is not acceptable.
