      Any cabling experts, need a bit of help re future fibre installation

      Hi all,

      New build house, 2009, with an external NTE.

      From reading around the net, Openreach may/may not swap your existing master, with the first extension it meets. Unfortunatley, after doing some digging around, the 'master' (remember, I'm on an external NTE), is 1 metre from the front door, nowhere near any power sockets, and the first extension (wires piggybacked into the first socket) goes to the master bedroom. I'm not prepared to have 20 metres of Cat5e tacked to a skirting board.

      This morning, I've rewired it as I think it should be, and it's all working OK. The main 4 wires (2,3,4,5) connect to each other at the hallway socket and the first bedroom, going straight to the lounge. From the lounge, I've used the spare green and green/white from the back of 2 + 5, back to the first bedroom, and then in turn, back to the hallway socket. I'm assuming this is all Openreach would have done?

      I just wanted to check two things:

      1) Is it now correct, and will I be ok for fibre in the lounge?
      2) Should the two orange wires be swapped around? To me (and I could well be wrong), it appears the solid orange wire connected to 3 on the xNTE, is going into 4 in the lounge?

      Diagram, before and after, plus a picture of how a socket was to try and clarify question 2.
      Before



      After


      Previous socket (in this example, bedroom, but the hallway was wired the same).



      Many thanks

      The 2 active terminals are 2 and 5. Terminal 3 is for the ring circuit which is not required with modern phones and can be disconnected. The standard installation normally uses the blue/white and white/blue as the active wires. It seems to be the practise of BTO to bridge the XNTE when fibre is being installed, the first socket on the loop being fitted with an NTE5 with a filter plate. Provided the engineer is advised that the first socket is the one in your lounge and it passes any test he puts on it, it should be OK.

      Thank you, so using the green and green white to loop back from the lounge socket is ok at present then? I assume as part of the 'NTE5' you've mentioned, does that have additional terminals specifically for extensions?

      Might disconnect 3 and 4 as per your info then. I was a bit confused at first as to whether I've got 2 and 5 the right way around on my internal sockets, I've kept the existing wiring pattern in either case, unfortunately there's no visible numbers on those internal sockets.

      The NTE5a line box has terminals on the front plate for extensions. 2 and 5 will be the 2 centre terminals on your plates.

      Thank you,

      Last one, in terms of polarity for 2 and 5, does it make a difference/can you tell if there's an issue?

      For normal telephones it will not make a difference. The polarity is reversed when the called party answers. This used to be used with pay on answer coin box telephones to unlock the coin slot. I don't know if modems and FAX machines make use of this feature.

      Many thanks to you both, plus that's a good bit of trivia!
