Say... I don't know currently, but British home phone lines used a
separate ring copper line, because that line was separated from the voice lines at the entry box to the home. So the plug needed that separate pin. Presumably a very long time ago? When I lived in London in the late 90s, we had plain 2-wire copper cable running up the outside wall, seemed to be dating back to the 50s.
I don't know about England, but where I grew up, party line phones had a third wire used for ringing and hook switch. How that 3rd wire was connected depended on which of the 2 parties you were. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
