That is pretty much it (perhaps also SCTP RESTART). An ASP intentionally issuing ASP Down has not failed. If the SGP feelds that the ASP is not responding properly (getting too many errors, or fatal errors), it could also consider the ASP as failed (even though the SCTP association is viable, M3UA communication to the ASP is not possible). But then it should probably drop the SCTP association anyway. --brian > > thanks, > Dario > > > > > Brian F. G.
