req advice: best cable for broadband

I've been lumbered with a job where I need to install a brand new telephone
cable around the outside of a very large house. The cable will be quite long
(over 50m) and goes from the external BT junction box (high up on the wall)
to the master socket inside the house. I'm concerned most about preserving
the adsl signal and resilience to weather so can anyone recommend a top
quality wire I should use? ie: make, spec number etc. Thanks for any advice.

I thought the wiring to the Master Socket was the responsibility of BT.

It is, but I expect that the customer wanted to avoid the exorbitant
charges that BT make when they consider that a job is not essential.

same as BT use is best bet.

After all, the signal has probably travelled a kilometer plus down
similar already..

CAT5 works well enough, but its not exterior grade.

You can buy exterior grade Cat 5. Typically about twice the price of indoor
grade cable, so perhaps £60 for a 305 metre reel.

You shouldn't.

If you do, and BT spot at any future time that non BT spec cable has
been used, or the wrong sort of BT cable has been used, or the job has
not been done to BT specs, there will be exorbitant fees to "normalise"
the installation.

If you still intend to do it, you need to determine whether it should be
dropwire, external cable or armoured cable (it sounds like external, but
I'm no expert, and dropwire is probably an valid alternative anyway).

The strength members in dropwire are not intended to carry the phone
signal, and misusing them as such may cause intermittent faults or line
noise.

You need to use approved connectors and terminations. This will probably
be "jelly crimps" inside the external junction box. You also will need
to support the cable and apply any appropriate strain relief in the
correct manner.

I believe current practice is to terminate external cable (black CW1308
or dropwire) in a junction box as close as practical to where it enters
the property, and run white CW1308 internal from that junction box to
the master socket. Note that a "junction box" might just be a lighweight
surface pattress and cover with "jelly crimps" used inside to actually
joint cables.

If you use "jelly crimps", make sure you use 2 wire ones and not 3 wire
ones.

With really good chocolate biscuits the engineer will run the black cable
right into the house up to the internal junction box :-)

If it's not broken, mess around with it until it is

Is going up and through the roof space an option?

thats what I have. BT cable terminates there on BT internal connector
block. . Rest is CAT 5. To my own faceplate in my own backplate. BT
totally happy with that, as long as they don't have to lay the cables.
