That means the extensions are daisy-chained so all will stop working.

The external socket of the NTE5A will work for both phone and broadband, given a dangly filter.

Label the detached wires in some way so you know which is T2 and which T5 for if they ever get reconnected. It matters. Maybe a small sticky label in the inside of the faceplate with it written on?

As a point of interest, post here what colour(s) each terminal has connected. Not all builders electricians get that right, so we may as well check it here and now.

Here's a pic of the socket:

So the wire for pin 2 is blue and the wire for pin 5 is white with green stripes every inch or so.

A few years back I got a retired BT engineer to improve my line quality for me. I remember him saying that the wire colours were all wrong and that electrical cables had been used rather than telephone cables, causing increased line noise. He also moved the master socket, which was in the hallway (totally stupid), and is now in the study, and at the same time replaced it with this Openreach one - previously the socket was one single unbranded plate and indistinguishable from the others.

At the time his work resulted in my line moving from 800kbps to 1990kbps. So of course I compensated him generously

And as an FYI, my house was completed late 2007 by David Wilson, whose contractors Electract installed the phone cables (yup, electricians...), and also botched the electrics in the house. Basically, Electract are useless.

The extensions should really be using a pair of wires not one wire two different pairs, so should be using the white with blue stripes not green stripes. Are all the extensions wired this way?

LOL
Shall we say, I'm glad an BT guy has done what he can without ripping it all out . Saves me or anyone else here having to guess what's best to do. I expect he went round the sockets as well.

Remember it's not phone cable. Probably not twisted pair of any description.

The bit that has me foxed is that T5 and T3 (detached) both seem to have white/green.

It amazes me how telephone wiring just seems to be luck of the draw!

But it's all BT/Openreach's fault at the end of the day for leaving the extensions to the house builders.

The guy who improved them was great. I don't really know what he did, but it more than doubled the speed. He went round all the extensions. Am just confused as to how he moved the master socket and can envision some sort of disaster unfolding on Tuesday if the OR engineer susses it's been moved.

He probably won't, and if he does all you say is a BT engineer did it .

Very good... And true - just wasn't working for BT at the time hahaha

Sorry to ask so many questions, but how does moving a master socket work? What confuses me is that in my mind a master socket connection goes:
Outside premises -> inside premises -> master socket

And that if it's been moved it will now be:
Outside premises -> inside premises -> "old" master socket -> internal wiring -> "new" master socket
Which surely will cause a slowdown/line noise?

I must be missing something.

As long as the wire the ex bt engineer used to extend the incoming cable from where the master socket was originally to where it is now is to spec, cw1308 twisted pair 2-3 pair , and the connections at either ends test fine then he will fit the filtered faceplate , (should do some tests using a jdsu or exfo device) I say should, because not all engineers carry the test equipment with them, OR seem to think they don't need test equipment

to make sure that the line is ok and your getting sync with the cab , before unboxing and connecting the BT openreach modem to the master socket and mains power point
and waiting for it to obtain a sync, or if a BTretail customer, they will connect the home hub up as well and i think they also demonstrate that they can browse the web on your pc

Yes and no. You and he must have agreed to move the master for some reason, and without fresh wiring from where it was to where it is it won't be any different than if you had tried to use the extension socket in the study in the first place.

On FTTC/VDSL2 it could be a bit more significant.

Is there an extension socket in the hall now, or just a blanking plate with the connections jelly-crimped inside?
