We have just had Infinity installed in our flat. The current main terminal is in a bedroom where the engineer has installed an Openreach faceplate. There is currently a phone extension cable that used to be plugged into the original faceplate which leads to the living room where we would like the router to sit. The extension has 4 wires - orange/white, white/orange, blue/white white/blue (photo attached).
My question is, can I reuse this cable and extend the VDSL side of the main box to the living room by using an extender box (then plug in the router/modem to the eventual box). If so, what would I need to make this happen?
Thanks in advance!
you need to connect 2 wires to the connection shown by the yellow arrow and then the same 2 wires conencted to teminals 2&5 in extension socket you would then need to use a filter in your extension before connecting router. you may find a drop in connection speed when using the extension socket rather than master socket
Thanks for that. Can I use an off the shelf extension socket and does it have to be RJ11 on RJ45?
just a standard extension socket but you will need to use a filter
if MK3 then taking off front plate should expose the connections
Use either the blue pair or the orange pair to extend, don't use one wire from each pair.

The A-B internal connectors are unfiltered just like the top socket on the front.
Any voice calls equipment being connected must be filtered. The internal 2-3-5 and bottom socket on the front are filtered.
If you use the A-B connectors for an extension and only use the extension socket for broadband then no additional filtering needs to be applied at that point as it's no different to the top socket on th MK3, just a few additional metres of copper. However the square-ish RJ11 plug on a normal DSL cable won't fit into a normal phone extension socket so you can use a normal dongle filter to act as an adapter. The broadband side of the dongle filter is still unfiltered. Another option is to use a DSL cable with a phone type plug on one end. Another option is to use an extension faceplate with an RJ11 DSL socket. Another option is to use an extension faceplate with a built in filter and both phone and RJ11 DSL sockets on the front.
If you intend to also use voice calls phone equipment on that A-B extension then you must apply filtering to the voice calls equipment either using a dongle filter or a built in filter.
The dongle filter is a simple cheap way of adapting the socket type for a standard RJ11 DSL cable and also putting in place voice calls filtering should you connect up a phone at that point as well.
Note: Broadband equipment won't work at all on an extension/socket that is filtered for voice calls.
