Usually blue/white and white/blue wires from A&B on the back of the BT ADSL V10 NTE5 filtered faceplate to terminals 2 and 5 on the ADSL-FFP85D - Solwise ADSL Filtered BT/RJ11 Faceplate (do not use F2 and F5 for adsl, they are for a filtered voice extension only)
For that setup only two wires are needed, i.e. blue/white and white/blue, since the raw signal will be unfiltered from the BT ADSL V10 terminals A&B to the terminals 2 and 5 on the back of the Solwise ADSL Filtered BT/RJ11 Faceplate. This will provide a rj11 adsl connection for a router and a filtered connection for a phone plug on your extension.
