This is a term which needs consistent definition before we continue. It's 
being used in different ways, including as you noted above.

Since the term is "Admission", I believe it only makes sense to use "CAC" it 
to refer to the control that is placed on deciding whether or not to admit a 
new call (i.e., packet flow), not on anything that is done later to decide 
whether to preempt a call or terminate a packet flow.
