!uccessfulI

; sinallin messae e'plicitly indicates that the elementary procedure successfully completed with thereceipt of the response.

nsuccessfulI

; sinallin messae e'plicitly indicates that the 2P failed.

; On time supervision e'piry (i.e. absence of e'pected response).

!uccessful and nsuccessfulI

; One sinallin messae reports both successful and unsuccessful outcome for the different included reAuests.The response messae used is the one defined for successful outcome.

1lass * 2Ps are considered always successful.

1lass 3 2Ps have one or several response messaes reportin both successful- unsuccessful outcome of the reAuests andtemporary status information about the reAuests. This type of 2P only terminates throuh response(s) or 2P timer e'piry.
