   It is probably not a difference worth dying for but to me "multiple   
   lines" implies multiple directory numbers (and in some sense or other,   
   multiple facilities*) and a whole different model from "call waiting"   
   and "conferenceing"  which are protocols for signalling to the switch   
   that you want the call currently on the single "line" put on "hold" at   
   the switch and either the waiting inbound call, or an originating   
   register connected to that single line.
