Re: Functionaliy of M3UA

Sergey,
Thank you for understanding, it's not easy to explaine on the foreign
language. I wish you will be kind to me :)
But lets get back to my question. I can agree that SG2 may send DUNA to
concerned active ASPs(connected to both SGs and placed in MGC), but what
message should send ASP to SG1( to the other one) to tell him about link
failure (at SS7 side of the SG2) in this case? Or ASP shouldn't do it?

Stan.
P.S.
Sergey, I think you are absolutely right (about politeness)!
