To clarify:

Suppose two systems initiate RMPP transfers to each other.  Each system 
would be sending and reassembling RMPP messages.  Both could select the same 
TID.

Upon receiving an ACK, a system knows that it matches with the outbound 
send.  A NACK however could match with either the outbound send or the 
inbound receive.  System A needs to know if system B is attempting to stop 
transaction from A to B or B to A.

Does that make more sense?
