I run my landline phone through the auxiliary BT socket. The router is in the master socket, which is placed in an inaccessible back of kitchen cupboard site in my flat.

The 3rd BT socket that services my Sky+ box (for Box office) no longer works. Rather than get BT in to fix it at great expense, I thought of running an extension from the working landline/ aux socket to the Sky+ box.

Apologies for technical ignorance here. I believe I can get a type of double adaptor for the socket so that I can run the phone and Sky box line off it. What's it actually called (so I can buy it online) and how do I fit it so that it has the ADSL filter in it? (which I need to keep plugged in or my internet connection drops)

thanks for your help & please keep any replies simple. cheers

You need something like this if I am understanding you correctly

Converts a single BT phone socket into two.

If you plug the double adapter into the phone socket on the ADSL filter that will filter both the phone and Sky connection. If you plug the adapter into the phone socket then plug the filter into one outlet on the doubler you will also need a second filter on the end of the extension lead where you plug the Sky box in.

So either

Phone socket --> ADSL Filter --> Doubler
Doubler Out 1 ---> Phone
Doubler Out 2 ---> Sky extension --> Sky box

Or

Phone socket ---> Doubler
Doubler Out 1 ---> ADSL Filter --> Phone
Doubler Out 2 ---> Sky extension --> ADSL Filter --> Sky box

BT is responsible only for the master socket. You can replace any secondary socket (and wiring) yourself at minimal cost.

Is your secondary socket not working because the connections are corroded or because it is disconnected inside, or disconnected at the master socket or because the cable is damaged? It's not difficult to check.

Never do it this way if you can possibly avoid it. The filter is designed to work with a single appliance connected. If you connect it to a splitter so that two appliances can be connected, you lower the impedance that it's feeding and that will often change the filter "crossover" frequency, so it doesn't work properly. You will either hear unwanted noise on the line or your broadband speed will be reduced. Even worse, the broadband may become intermittent and the cause may not be obvious (unless you've read this).

If you must do it this way, use an "active filter", which can cope with a greater load.

thanks guys.
So is option 2 better then? ie Phone socket ---> Doubler
Doubler Out 1 ---> ADSL Filter --> Phone
Doubler Out 2 ---> Sky extension --> ADSL Filter --> Sky box

I bought a doubler off amazon. Thanks for the tip re not getting BT but someone else. An extension would be easier though as don't use it very often (occasional Sky Box Office )
The BT connection was disconnected when the whole Sky socket was moved to another wall. The satellite guy just didn't bother to run it to the new socket

Sorry to highjack this thread but I can't find a telecoms section on the forum.
I am getting a duhdudduh duhdudduh noise on a phone line. I have turned off the router and it is still there. It is on a French POTS line with doubler (for a fax machine). I have also tried removing the doubler, disconnecting all extensions and using a fixed phone in the master socket.
Any ideas?

Not sure what the noise you're describing really sounds like, but if it's an interrupted dial tone it could just mean that there's a message in your France Telecom voicemail box.

Thanks, I'll try to record the noise and the other thread. It's not an interrupted dial tone but definitely interference.
