Does anybody recognise this BT master socket?

[#1]

I have a funny BT master socket that has a small socket for VDSL and a normal phone socket for the phone.

So I can't plug anything into the test socket without disabling my internet.

The VDSL socket is so small I didn't even recognise it as a socket

Picture below...

[#2]

Looks like a standard Mk3 faceplate.

Unless I'm misunderstanding the question...

Surely with any faceplate you'll lose internet temporarily if you have to remove it to access the test socket.

Once accessed, you can then connect a phone, or a microfilter for phone + internet.

[#3]

I appreciate the temporary disconnection - but this causes a permanent disconnection. I think that there must be an internal filter?

this indicates that the Mk3 had the same problem 2015...

[#4 · Accepted solution]

I would suggest that the test socket is behind the lower cover with the two screws, but, I ain't seen anything like that before, looks a tad antiquated.

I've just had two new BT sockets and they're totally different. One even has a built in ADSL filter.

If you'd like photos let me know.

It is indeed!

Now knowing that it is a Mk 3 tells me that it is old...

 Use one of these so you can connect your internet to the test socket

If you catch any BT 'pole' lads out and about, they'll usually do foreigners!

There is NO filter in the faceplate DSL socket ! - It should be a straight through connection to the external landline.

Only the faceplate telephone outlet is filtered to prevent noise from any phones or extension wiring interfering with the DSL.

It may actually be a MK1 - the MK2 and MK3 have MK2 or MK3 printed on the top right corner.

To get to the test socket, you remove the part with the DSL socket as well as the lower front part with the telephone socket.

I stand corrected - I blame advancing years.

For what it is worth, I concur. 

I have a MK3 and the writing is there, but helped a mate the other day sort out his fibre, which also did not have markings on the socket. Should be an easy update to replace the faceplate with an MK3 or 4 faceplate. But the MK5 is a bit different, not quite worked out how they work, meant to be tool-less! But I still have my krone tool, nowt wrong with them 😉

[#12]

It's a Mk 1 then - no Mark printed on it.

It's so old that that they didn't use Mark numbers!

[#13]

Don't think it's a Mark 1 - that had a different layout with the PSTN and ADSL sockets side by side. Later ones have the same layout as your photo, with the DSL port at the top.

I was shocked, astonished, amazed and extremely pleased to receive an unsolicited phone call from Plusnet, yesterday at about 6pm. regarding line speed issues on this old socket of mine.

It was just like the Plusnet of old - proper customer service; they have arranged for a BT engineer to come out and look into things.

@Jaggies

Perhaps you are thinking of the older ADSL faceplates. There are pictures of some the old ones, (no longer available to buy), here: https://www.run-it-direct.co.uk/adsl-vdsl-faceplates

@VileReynard

It's not that old, it probably dates from the early days of FTTC.
