Hi All,

This is regarding M3UA SSNM messages.

1. Take an ASP with 2 SCTP link sets with each link set having 2
associations, connecting to two different SGs.

         | - - - - -> Link Set 1 (2 Associations) - - - - -> SG 1  - - - -
- >|
ASP  |
                         | HLR-1
         | - - - - -> Link Set 2 (2 Associations) - - - - -> SG 2  - - - -
- >|


    If all connections between SG-1 and the HLR-1 break,  the ASP would  be
notified with a DUNA.
    My question is through which SCTP connection between the ASP and SG-1,
the DUNA would be sent in a proper SG implementation?
    Would it be sent to both connections or to a randomly selected one ?



Thanks and Regards,
