Recently moved into a new flat - a new build which had never had BT service before. A master socket (newest type with the Openreach logo) is present in a cupboard with the electricity box and other utilities. There are also 3 extension sockets in various places around the apartment. The developer warned me that while the wiring is in the walls BT will need to connect the extensions to the master socket but I forgot to ask them to do so when they enabled the line so I'm now looking at doing it myself.
I've taken a photo of the master socket here but it was quite hard to take due to the small cupboard the socket is in.
Simple quesiton really - which of the exposed wires, if any, should I connect to which terminals on the master socket front plate to get the extension sockets to work?
As a side note the DSL (Be ADSL2+) running on the line, while decent for a very short line, is a fair bit below average for the attenuation so I'm wondering if there's anything else wrong with the wiring in that socket - can't see anything obvious though and the DSL is connected to the test socket so there's probably nothing I can do.
Apologies if this is the wrong forum for this but most of the phone wiring threads seem to be in here.
