does the sockets look like any of these

Going by what you say it looks like you have two master sockets if you can unsrew the faceplate and there is a test socket behind each of them. It looks like Openreach didnt know about the socket in the cupboard and made another main socket / OR the master socket was moved but the ORIGINAL left in place BT stamp is the older one which makes sense as it is in the cupboard maybe not used for BB at the time. The line connections are 2 and 5 - connection 3 is for the bell circuit If both master sockets are connected to the line you will have 2 capacitors in circuit only 1 is required. The line colours arent the same as I used. blue/white/blue were across the line[2+5] Its possible that the sockets and colours, but I have the original book of connections when the new socket system was introduced,- have changed since I worked for them but there still should be only 1 master socket.

Welcome to the forum kates2787......
The usual method of wiring goes like this.......
The incoming bt line goes into a junction box, normally just inside where the line enters the property. The line then goes to the rear of your master socket. There should be no other line connected to the junction box. At the rear of the master socket there should be 2 wires connected, Blue (with white stripe) connected to terminal 2, and White (with blue stripe) connected to terminal 5. All of the wiring up to this point is the resposnibility of openreach and should not be touched.
Any extentions that you have are connected to the rear of the faceplate (which, in turn, plugs into the test socket). By using this method, your internal wiring can easily be disconnected from the bt line.
Hope this helps.....

The A +B you refer to are the old connection box and is the incoming line the old ones terminated on screws not on the slotted strips with 1+2+3 one side and 4+5+6 on the other which can be removed. This is so that hardwiring can be sotted into the detachable part by using a Krone tool . THats the OLD way of working. Its obvious that the modern master sockets are different but not in the connection numbers=2 and 5 for the line and 3 was on the removable strip. Its just you have old and new designs in your house . If I was there with you I could fix it in 5 minutes.

John--If there are two master sockets then 3 should be removed from the -second -openreach master socket. Not from the first-BT- as that supplies the capacitor circuit for bell and speech path[through other circuits in the phone] to any extn. I realise many modern phones will work with just the line and no -3-connection but that isnt universal. especially if they fitted a old 746 bell phone or bought an antique 300 type bakelite[both with modern plug cord].
