1.	Start traffic to B and C with SI=X.		
2.	Send a UPU from B to C with SI=X.		
3.	Check that the UPU message is received correctly without impact on the traffic from to A to C.

Note – The notion of unavailability of a user part is specific to the implementation, consequently, the ability to deactivate a user part is implementation dependent. The SPs having user part(s) are concerned.			
TEST DESCRIPTION			
1.	Start traffic to B and C with SI = X.		
2.	Deactivate the user part X.		
3.	Send a message from B to the user part X in A and check that this message is discarded and that a UPU is sent back.		
4.	Send a message from C to the user part X in A and check that this message is discarded and that a UPU is sent back.		
5.	Repeat point 3 and reactivate the user part.
