BT test socket

Because the main socket connects to the test socket?

The point of it is that there's no extensions connected to it, so when you're using that your extensions are out of the picture...
 
Yeah I believe it does.

ISPs always ask to plug in to the test socket if your having problems with your broadband. My thinking is why not just bypass this supposed weak link, and make the test socket the main socket.

Just seems strange to me.
 
Because the whole point is eliminating your extension wiring?

(It isn't a question. I know it's the case.)
 
The main socket is there to allow extensions to run off it as far as I'm aware. If you didn't have any extensions, you could run off the test socket with no problems at all, but if you were to make the test socket your main socket, then the extensions would have nothing to connect to (since they connect to the back faceplate that is the "main" socket), and so (obviously) wouldn't work. Good question though, I know quite a lot of people can be confused by this when they only have one socket in their house :D
 
Yeah, if you don't have any hard-wired extensions, the socket on the faceplate and the test socket are basically the same thing.

"Use the test socket" is basically an idiot-proof version of "try your connection without any extensions".
 
Not quite - the sockets on the front of the faceplate are either filtered (voice side), or the same as the normal faceplate with a different socket (ADSL side).
