Here are some images -

Basically, no one seems to know what this cable with the different coloured wires coming off it are for! Originally, this box was on my wall with the wires plugged in. I took it all off not thinking I would need it, but now I actually do.

What box is this? It was just screwed into the wall. I want to buy a replacement so that I can get this extension working again. Does anyone know which colour goes where?!

Also, would Infinity work with this extension box?

Thanks

    The cable with the different coloured wires was probably being used as the phone cable. How it is actually wired is anyone's guess as whoever installed it could have picked any two of the four cores as the line pair. So the only way to be certain is to trace the wire back to wherever it starts out from and see which wires are connected to which terminals. Terminals 2 and 5 are the line, 3 may be used with old phones but can be unnecessary with modern phones. Any other connections can be ignored.

    The socket is a filtered LJU type faceplate. You could just use it as is and ignore the ADSL socket or buy any LJU 2/3 type Secondary socket to replace it if you just want a simple phone extension.

    You can get types with screw terminals which may be easier to connect than the IDC terminal types that require a special tool to punch down the wires into the terminals.

    Not sure what you mean by "will infinity work with this socket". In another thread it seems you have a BT filtered NTE5 master socket. If so then there is no broadband signal on the extension wiring as the master filters it. So without changing the master back to a bog standard unfiltered type you will not be able to use this socket to plug the HomeHub into. Assuming it will as the NTE5 socket is RJ45 type and the ADSL socket on that faceplate is RJ11 type (a RJ11 plug will fit RJ45 socket but a RJ45 plug will not fit a RJ11 socket).

    Also I would be wary of the cable type. It may not be properly suited to use for broadband signals, especially Infinity type signals. So may have a detrimental impact on performance.

    Also if you did get this socket working you will need to fit filters on all other sockets with a phone plugged in to prevent the phones interfering with the broadband signal which would now be present on that wiring if you removed the filter in the master.

    The socket may be RJ45 on the NTE5 but I don't think the cables are - they are RJ11

    Couldn't you attach the filtered faceplate extension wiring to the two unfiltered connectors on the VDSL filter? Then the phone side would of course be filtered by the extension faceplate and the DSL side should work for the HomeHub (assuming the filter is good enough for VDSL of course)

    Ok, I unscrewed the master socket and look at this -

    The same wires that are in my lounge are wired into the master. So if I now wire the other end which is in my lounge, the same way this is wires, into one of these:

    I'm guessing I could plug my home hub 5 box in the lounge then? There was a very similar box in the lounge before but I removed it as I never thought I'd need it.

    The bog standard Openreach filtered NTE 5 doesn't have unfiltered extension terminals as far as I am aware

    There are third party sockets that do have both types.

    As the filter removes the broadband signals from the phone socket and leaves the ADSL socket directly across the line the only effect it could have is loading of the line affecting the frequency response.

    If the master socket is a filtered type as shown in your other thread in the BT Broadband forum it likely won't work. If you have a filtered master the terminals for the extensions are also filtered so have no broadband signal on them.

    If you were to wire onto those and plug the HomeHub into the extension socket it will not work. The extension needs to be connected to unfiltered terminals which I don't think a bog standard Openreach socket has unless you remove the additional filter section and restore it back to a standard NTE 5 master with just the phone socket.

    Why was that cable connected to an ADSL/phone socket in the lounge then if it didn't work?

    It may be from a previous installation before Infinity was installed. In that case the master socket may well have not been filtered so these filtered extensions could have been used to allow the router to be used anywhere or simply as an alternative to plug in filters which would otherwise be needed.

    The socket will work as a phone socket, just not as a broadband router socket, with the filtered master socket. Though the filters in the sockets are a bit wasted in this scenario.

    Thanks. Could I potentially take that cable out of the master socket then if it's useless?

    Depends if you want to plug a phone into it or not. As I say it will work for a phone just not for the HomeHub.
