And the last two of that style of faceplate I have seen have been connected direct to the line with just a back box behind.

I have taken the faceplate off.

Behind it is a white BT master socket, so should I change the faceplate to an Openreach VDSL2 Mk3 interstitial filter plate, or is there a better alternative please?

Whatever the answer where is the best pace to purchase - "best" in terms of getting a genuine product not a copy?

Thanks again.

So, that now answers my question from yesterday morning.

Yes, change it to a better quality faceplate. The BT Openreach one will be fine and when you purchase it, get an IDC tool too (if you do not have one already).

A few years back I did some testing of the frequency characteristics of a few ADSL and VDSL faceplates. Whilst they would work, the ADSL faceplates started to present nasty impedances at the higher frequencies and could cause phase shifts, impedance mismatches and large attenuation spikes - all of which would cause problems for VDSL. They would work, however they would not be of te optimum performance.

And?


I asked where the Master was - not what the faceplate looked like.

In reply to a post by MHC:

You are getting confusing replies here, particularly from MHC.

That ADSL faceplate you have originally replaced a standard NTE5A faceplate. As well as the interstitial Openreach Mk3 VDSL filter plate you will need one of those.

On this page you can see what you will end up with, and as you scroll down it you see on the right the stages of dismantling it to get at the test socket.

The first item removed is the standard faceplate I'm referring to. The next is the filter plate, leaving the master wall unit with the test socket.

Your existing ADSL faceplate cannot be used with the interstitial one, and that doesn't come with one.

I gather there are extensions, or at least one. We need to know how many wires are attached to your faceplate - preferably with a photo showing them uploaded somewhere . This is so we can give you best advice on what to do. There could be other complications to do with getting the best possible result.

In particular if there is more than one physical extension socket in the house. Whether or not you use it.

Clearly if that's the case then it would be tampering, but that looks very much like the ADSL nation faceplate which simply screws onto the front of an NTE5 and replaces the smaller inset faceplate with a phone socket. There used to be a BT version that did that too, but that seems to have disappeared and you can only get the interstitial plate (which isn't much use if the OP no longer has the smaller inset faceplate.

I did post the OP to check that.

I think the two faceplates you are talking about - the ADSL Nation one, and the original BT-installed one - can be found on this page:

The second image within "step 3".

I had one of the BT-installed faceplates fitted by BT in 2000, in the original ADSL trials. I used one of the ADSL-Nation ones for my parents in Hull (KC use the same split NTE5's).

I had the ADSLnation one too, but when I had a line problem I just put the original inset faceplate back and disconnected the extensions when the engineer arrived. I knew full well that it was nothing to do with the domestic wiring, but it was easiest to keep thinks simple.
