So the one coming from the junction near the bracket down to the NTE/SSFP is drop wire 6 and will need to be replaced if your having the second line near the existing socket.

If the drop wire going from the bracket to the pole is a one pair (drop wire 11) then it'll need to be replaced in that case try and get the engineer to replace from pole to both sockets in one continuous span (no joint at bracket). If it is already 2 pair (drop wire 10) or 4 pair (either drop wire 14/15) then this won't need to be replaced an in that case the engineer will just renew from bracket down to socket.

You should see a small improvement in speed on your existing VDSL service when that section from bracket to NTE is replaced.

If your having your second line in a different location the engineer won't replace that section as he will need to run two separate drop wires then for only one task he has been given.

Excellent info, thanks.

I'll put the sockets next to each other, they are going to be going in to a Draytek 2860ac, so this is most convenient anyway.

I do expect that any gains I see will be offset by the crosstalk between the two lines!

I'll hope the overhead cable is drop wire 11 then

Cable from the pole is 2 pair, so probably drop wire 10.

Engineer is replacing the wire and junction box from the point it hits the building, so will still have a junction

Waiting on the final bit now. I have casually thought to myself that if I ordered a 3rd line, the overhead would HAVE to be replaced.....

Oh, and it's been raised as a copper only install, so I suppose TT are going to do wires only for the FTTC part at some unspecified future date. Wonderful, now I have to buy a faceplate....

edit: Post install stats, only one line provisioned, but this is with the replaced drop cable.

Will post the other line once provisioned with VDSL
