Note – n is the maximum load capacity of linkset 2. The traffic model used in this test is described in Table 2/Q.706.			
TEST DESCRIPTION			
1.	Start traffic to C with a load exceeding n/2 erlang on links 1 – 1 and 1 – 2 (n is the maximum load that the link 2 may carry without congestion).		
2.	Check that the signalling traffic flow control procedure is started in A. Check that a TFC message concerning C is received for each 8 messages received in B during the congestion.		
3.	Reduce the load to 0.1 erlang or less on links 1 – 1 and 1 – 2.		
4.	Check that the congestion disappears and that no TFC is received.		
5.	Stop traffic.		
6.	Check that the traffic from C to B has not been disturbed.
