this may seam obvious to some but im still a little confused if my external line from house to pole (the part before the little black joiner) dose have 2 pairs after all and they do both lines off that 1 line, Dose that mean that both lines will share a wire all the way back to the cab or just the wire between my house and the poleLet's assume you go out and stand at the foot of the pole. What do you see? At least one (maybe more) multipair cables coming out of the ground, travelling up the pole (under a galvanised steel protective "U" cover until above the height of the average chav's reach) to one (maybe more) junction box(es) at the top.
At the pole head, your drop cable is attached to a "halo" ring and then enters the junction box. Within that box, the working pair of your drop cable is connected to the bigger multipair cable which, as you have already noticed, comes out of the ground. That multipair cable then travels to a jointing chamber where it is, in turn, connected to an even bigger cable which makes its way to the PCP. At the cabinet, all those D-side pairs are then "fanned out" and are connected to air pressurised E-side cable(s) which run to the exchange. If there is more than one E-side cable feeding the PCP it is at that point were one pair coming from an EU (you) could be connected to one E-side cable and the second EU pair could be connected to a different E-side cable.
So, in summary, you could end up with this situation with your two lines:
(1) Two separate NTE5/A in separate locations in the house, each fed by its own cable.
(2) Those two cables are joined at a "black sausage" (at gutter level) to a single multipair drop cable.
(3) At the pole head, the two pairs in the drop cable are connected to a bigger multipair cable.
(4) The multipair cable descends the pole and travels to a joint chamber.
(5) In the joint chamber, the multipair cable is connected to an even bigger cable.
(6) At the PCP all the D-side pairs are "fanned out" and connected to (one or more) E-side cables.
(7) The E-side cables travel to the exchange.
Obviously every situation is different and what I have just described is what may be the case for you, after Thursday.
