I understand the Data Extension Kit is to avoid having the modem next to the master socket. So it plugs into the master socket and allows to have the VDSL socket and modem elsewhere (without using existing wiring which may not be of sufficient quality).
So your choices are (assuming you don't want everything at the master socket):

master socket --> data extension kit --> VDSL socket in another room --> modem --> ethernet cable --> router

or

master socket --> modem (near master socket) -> ethernet cable --> router

Your router can always be in a different place as long as you can run a long enough ethernet cable (which can be much longer than the 30 metres Data Extension Kit).

So essentially the Data Extension Kit is an extension socket, albeit isolated from any other existing wiring?

The way I reworded it is how I'd probably prefer it. i.e. site the modem as close as possible to the master wth no extension (or very little). Adding 30 metres of extension wiring seems like a very bad idea.

Are you sure?

No, my reword is how I imagined it to work.

But Plusnet's description does appear to be total garbage as RobertoS suggests.

(I always forget which is RJ45 and which RJ11, and aren't those socket specs anyway not plugs?)

They are socket and wiring specs. So The socket in the VDSL faceplate is technically not RJ45 even though it uses the same socket as "standard" RJ45 - and neither is the one in your Ethernet switch / router / etc because ethernet wiring is different from RJ45 wiring. To make matters more confusing, RJxx is commonly used to refer to both socket and plug, again incorrectly,
Anyway, in the common usage RJ45 is the 8 position plug/socket used for ethernet (and also in the VDSL faceplate, confusingly) and RJ11 the 6 position plug/socket used for ADSL connections (normally with just the two middle wires connected, making it a real RJ11, but if 4 wires are connected it is technically a RJ12).

That would be better as it avoids any extra noise introduced by your home equipment. But you do that without the Data Extension Kit (Home Wiring Solution / whatever it's called this week) and running your own cable from modem to router.

It used as RobertoS states here.

Not sure what to make of this reply... it is just a link to the post I was quoting?

I think a reword is needed. There appear to be four entities: master socket, data extension socket, modem and router. I think your order page with the Fibre extension kit option needs to mention all of them. "Keeping it simple" is in fact adding confusion.

It certainly looks that way. As it is I don't hesitate to call it misleading.

Your router can always be in a different place as long as you can run a long enough ethernet cable (which can be much longer than the 30 metres Data Extension Kit).

this seems to be the most sensible option..
we can always try router at different locations with a long ethernet cable...
i think i will ask for this tomorrow.
