Needs clarification on handling of SCON message

Hi,

I have one query regarding the SCON message handling between SG and ASP.

Suppose a SG informs one of the Active ASP serving an AS that one of the point code in MTP3 network has become congested and hence sends the SCON message with congestion level say 1 to ASP.

After receiving the SCON message with congestion level 1, the ASP starts the audit procedure and starts sending the DAUD message for that destination.

Now when the destination point code in MTP3 network become uncongested, can a SGP inform the ASP by sending a DAVA message or it always informs by sending SCON message with congestion level as 0.

And what if say after sending the initial SCON message to ASP with congestion level 1, the SG gets restarted. After restart would it be a DAVA message sent to ASP, on receiving it the ASP clears the congestion level set earlier and marks the destination point available and informs the higher layers.

Regards
Deepak
