         As an "old" Bell Canada telephone installer, I have been following 
this thread and must comment. In the earlier days when there were party 
lines, (two subscribers to a single line), the Yellow was always connected 
to ground and so three wires were required and the "ring" power (~90VDC) 
was supplied to either the red or the green depending on which party was 
being called with the completed circuit going to ground.


"R"ing was "R"ed
Green was Tip
Yellow was ground
Black was "Extra" and usually not used.

         Today the red and green are used for one line and if two distinct 
phone lines are in your home, the yellow and black are used for the second 
line. I also found out the hard way recently that it does make a difference 
which way the lines are connected to the modern phones as I had to reverse 
the red and green to make an extension work. Polarity is important.
