UK Phone wire colour codes?

I have unearthed an old phone extension cable that I want to use.

Modern BT (Brit Telecom) wiring for extension is :
Terminal 2 Blue/white wire
Terminal 3 Orange/whiterings
Terminal 4White orange rings
Terminal 5 white/blue rings

Terminals 1 & 6 not used

However, the old extension cable has four wires coloured blue, orange. green and brown.

Anybody know which goes to which terminal?

Yrs, frustrated...
