Hello,

I think my house has got a bit of a weird wiring set up, and just wondered what you think of it. Also every time the phone rings the SNR drops, sometimes the internet cuts out altogether.

This is where the line is coming into the house next to the front door. As you can see there is also a line coming out the side.

This line leads into the garage to a BT DACS2 box.

It then comes back out of the garage and into a bedroom upstairs.

This is the socket that it leads to, I've looked inside (not touched only looked) and there is only the two blue/white wires that are connected to the A & B points, all the rest are coiled up. The internet works ok in this socket, sometimes with a slightly less line attenuation but still cuts off with the phone, if anything more often too.

This is the main master socket (I think!) in the living room downstairs, pretty much the other side of the main grey box on the wall.

Inside there are no wires connected to the A & B points, but there is some extensions joined. The blue and white cables are joined to some other ones the same and they go elsewhere. The internet does not work using the test socket with this one. (Upstairs it does)

Lastly there is an extension socket in another bedroom upstairs with a phone plugged into it.

I only took any notice of this wiring when the BT filtered face plate that I bought did not work in the master socket.

Here is routerstats showing the SNR over about an hour or so. The drops are when I rang the phone.

And here's the router stats, It's a Billion Bipac 7800n.

If anybody's got any thought's on this that would be great!

Also the house is about 20 years old.

Cheers!

Two of those photos are the same.

I think the BT filtered faceplate should work in any socket that the test socket works in.

If you take the lower front plate of whichever socket is the actual master socket, all the other sockets should be completely dead.

I suppose at one time, the property might have had two different phone lines, maybe using DACS, but later that was disconnected and one of the master sockets re-purposed as an extension socket.

I changed the photo that was the same

I took the front off the socket in the living room... The internet plugged into this socket still carried on working, and the phone upstairs worked in both sockets.

I also took the front off the socked that goes through the DACS box in the garage, So even with the front's taken off both sockets everything still worked ok.

The third socket is not an NTE5 so there's no front to come off.

Then I suppose it's a mess of star wiring, where each socket has been independently joined to the incoming line. Probably not optimal for broadband, but it might not be too bad, personally after my star wiring was sorted out, it made absolutely no difference whatsoever.

[ben_strange]

I'm not that bothered about the fact that the wiring is a mess, It's more the fact that when the phone rings the SNR dips, sometimes not by much but sometimes it disconnects.

[ejs]

Your ISP should accept the broadband disconnecting when the phone rings as a broadband fault. If it were only dips in the SNRM, probably not. I expect most Openreach engineers would install a new master socket and disconnect the star wired extensions. The fault could be elsewhere on the line or even at the exchange. You can't guarantee that you won't get an engineer who would disconnect your extension sockets, and if that solves the problem, then decide that the problem was with your extension wiring and so you'd get charged, but you could always argue about any charge with your ISP later. Some ISPs have their own engineers who do the master socket and internal wiring work.
