As we don't fault to component level, I wouldn't know for sure Walter ?

A far as I am aware, surge supressor (gas discharge tube) is now located in the exchange, as opposed to the NTE5. Again, I'm not sure at all, but would hazard a guess that the capacitor and resistor still found in the internal NTE's, is also present in the external ones ?

Maybe Ezzer has more knowledge on this, or anybody else for that matter ??

There would ideally be some sort of surge protection at both ends of the line. The one at the exchange end must presumably be one of very high performance, to protect the exchange under the most extreme circumstances. The one at the user's end predates broadband and was probably designed only to give some protection to telephones, at minimal cost of course. I wouldn't be surprised if there isn't one at all now with the XNTE, and if I had one of these I would connect it directly to an NTE5 internally for the small extra protection it provides, and also for the convenience of the test socket.

Seems it's now a '26A overvoltage protection' device.

Great link 4candles.

[roseway]

Yes, really useful, thanks.

Aye, cheers. I was quite surprised to find it, as it didn't appear when I last tried to find info on the XNTE a while ago.

I knew I had seen that information, hence my earlier posting. Thanks for providing the reminder, as I couldn't lay my paws on an explicit reference. For any OR device specification, it is always worth checking the Pressac website. In particular, the downloads page is a valuable resource.

I double checked the wires in the External NTE and the sockets.

In the XNTE. White w/ Blue is in 2, and Blue w/ White is in 5.

In the sockets. White w/ Blue is in 5, and Blue w/ White is in 2.

As you can see they are not going into the same terminals, would it be highly recommended for me to remove the wires in the sockets, then put them into the matching number with an IDC tool??

Or would wiring these into matching terminals not really help?

As mentioned I may just disconnect the additional sockets if I re-wire too.

Hi Dan,

The external NTE is following the usual convention so if you are making any internal changes it is sensible to swap them round inside.
I would certainly disconnect all the other internal sockets to be begin with and run your service like that for a week or so.
If you then want to reinstate any sockets you have a good reference record.

This might seem rather pedantic but it is following RP's advice to disconnect unwanted extension sockets.

Kind regards,
Walter

@Walter. The correct pair colouring is green, blue and orange. In other words:

IDC    Colour

 1       Green/white stripe
 2       Blue/white stripe
 3       Orange/white stripe
 4       White/orange stripe
 5       While/blue stripe
 6       White/green stripe

So it is within Dan's XNTE that the blue pair are incorrectly connected. Of course they could be connected that way because the A- & B-wires have been incorrectly terminated under the "red cover". I really need to DVM probe inside that XNTE!

Would an OpenReach callout via my ISP confirm what is happening under the red cover?

Even if under the "red cover" it's the wrong way, shouldn't the internal wiring terminals match whats in the External NTE in terms of numbers/colours?

I.E Should the wire in 2 in the XNTE be the same wire in 2 in the terminals on the sockets?

I have an IDC tool coming tomorrow so I can make changes if necessaray. I will also be disconnecting other sockets other than the 1st one when I have the tool int he next day or two.

B*Cat is correct.

Should the terminals in the internal sockets always match wire colour-terminal combination with those in the External NTE?

Are the blue/w and White/b any different other than their colour?

Basically is it worth me when I disconnect the additional sockets switching over the wires on the first socket so they match the colour-terminal combination that the XNTE is wired as?

[HPsauce]

Should the terminals in the internal sockets always match wire colour-terminal combination with those in the External NTE?

No.

Just make sure that you use a pair for 2/5 e.g. white/orange and orange/white.

OK thanks.

Next thing i'll do is disconnect the additional sockets so we are just running off the 1. I'll leave the wiring going to the same terminals they are now, but just disconnect the second pair that passes on to the next faceplate upstairs.
