A.  I can't understand how your phone could have rung on a 2nd
    call w/ call waiting.  Ringing voltage (90v 20~ AC) is not
    applied to the line for the second call.?????

    You say you "were on the other line.", there is no other line
    in call waiting.  The central office switches you between 2
    different trunks in the CO, but there is still only 1 line to
    your house.  If you had 2 lines and key equipment then that
    could explain the situation.

B.  Call waiting works differently on different switch
    technologies.  That may explain part of your observed
    behavior.
