ASP3 in INACTIVE state. ASP1 and ASP2 are in active state and handling traffic. Now if ASP2 moves to inactive state then notify" insufficient ASP resources" is sent to ASP3. In this situation if any ULP data is received at the SG for the AS what the SG should do??? Option1: Send data to ASP1? OR Option2: Buffer data until number of active ASPs=n? Q2: What if after the above notification ("insufficieant ASP resources") is received at the AS end no ASP initiates ACTIVE procedure? The RFC is not clear about it .

A third option for this case, which you didn't mention, would be to send an SS7 msg back to the sender, indicating that the destination is unavailable.

Q2: SG continues to send DATA to ASP1. Please have a look to M3Ua-bis document regarding those issues. The state diagram for AS has answers to your questions.
