Greetings All
What a great website and forum - I've learnt so much by reading it and your posts.
I was wondering if someone would please advise:
- my master socket is in a bedroom but our router is in the hallway. So far, I've used an ADSLNation extension socket in the hallway and it's been great, but it looks like the filter is now faulty after some 10 years in service.
- since ADSLNation don't make extension sockets, I'd like to connect another BT NTE5 socket to the master socket so that I can keep the router in its current place. The problem is that all NTE5 sockets have only A and B at the back of the plate, but we're still using an old/retro GPO phone that requires the bell wire. NB: I'd need a filtered faceplate at the new location.
Would someone please advise where to connect the bell wire in the extension NTE5 socket? See the illustration showing what I'd like to achieve.
Thank you for all your help in advance.

You don't want more than one master socket on your line, as that will cause issues.
However, it sounds as if https://telephonesuk.org.uk/wiring-info/ has the wiring information you are after

Personally I'd say replace the phone, as having the bell wire connected often causes a lower broadband speed.
Or use something like this (https://amzn.to/3tllNpj) and a plug in microfilter.

Thanks. What issues, though? Wouldn't it just function like an extension socket then with filtering taking place at the extension, rather than the master socket itself?

I like my retro phone.
I've previously had a Dec phone (gigaset) and noticed more issues with CRC errors appearing than with my gpo phone. Speedwise, it wasnt much of a difference, and even if it's just 1mbps, then it won't matter with vdsl2 as 63mbps Vs 60mbps makes little difference to me

As already said, it's not good practice to have more than one master socket on a line.
A simple, if not the most elegant, solution would be to put a standard socket at the end of the AB connection from the current master and use a decent rats-tail filter to connect your GPO phone and router to.

Look, appreciate your comments, but that's not what the question was about. I know it's not a good practice etc etc, but given the current set up, I have to another socket without dangling filters.

bell wire can be susceptible to RF interference, if you are still looking to do this, two pairs from a shielded ethernet cable would reduce the chance of RF interference.

You don't need 3 wires from the original master to the secondary master.
If you really must bodge this, then simply just wire from the data extension terminals of the original master to the incoming terminals of the secondary master.

I can't think of any other way if a rat-tail filter is off the menu. It is a bodge as you say.

Sorry, who is talking about it being a bodge. It'll be neat and tidy, and all connected properly.

How's the bell signal fed?

Modern filters filter out this interference, don't they?

Yes but extension wiring adds interference.
Shielded ethernet would give a cleaner signal than filtering extension wiring.

How's the bell signal fed?
The second master socket will supply it via its bell capacitor.
If you do go this route I'd cut the out of service resistor from the second master as only one is required on a circuit.

In exactly the same way as when the phone is connected to the original master socket.

The best way to do this correctly would be to relocate the master socket to the hallway. Officially only Openreach are permitted to do this of course.
My original ADSL setup had the master socket in the hall and my modem in the study running from an extension. Because my extensions are star wired I put a filtered faceplate on the master and ran the study extension via AB using a rat-tail filter as I advised earlier. This all worked perfectly well.
When Openreach later installed my VDSL service their helpful chap relocated the master to the study by using my existing extension wiring to take the line directly to the new master and then back to the old master location to connect to the other extensions. The joining of the line to my extension wiring was done using jelly crimps behind the old master socket.
This does require you to have at least 3 pair extension wiring (ie 2 wires for the existing line and then 3 back to the original location) for this to work. Luckily I did have such wiring in place.

How's the bell signal fed?
From the mid-point of the series connected resistive-capacitive shunt across the pair in the master socket.

Would you put it into different words so that it's accessible for those who don't know the terminology? Thanks.

See reply 15
You can't put a technical answer in anything other than technical terminology.
