> Mark Phillips, G7LTT/NI2O > Randolph, NJ It's not done that way in the UK. BT (via OpenReach) will install a 2nd master socket for a 2nd phone line. Internally we normally run 3 wires. The 3rd wire carries the ringing current, isolatesd via a capacitor - also acts as a "tinkle suppressor" which stops bells tinkling on other phones when you use a phone with a loop-disconnect dialler. Here's an example: http://www.wppltd.demon.co.uk/WPP/Wiring/UK_telephone/uk_telephone.html In these enlightened days, it's normal to not use the 3rd wire internally on extension as it has been known to degrade an ADSL signal.
