Hello Sundar,
In case of IUA, Each interface Id related mesgs will travel on a specific
SCTP stream ID,
u need to build a table which co-relates the InterfaceId ----> SCTP Stream
ID. Once the SCTP_COMM_UP
mesg is recved from SCTP the IUA need to build this relationship table
according to the number of Streams
SCTP supported by the "SCTP association" between the SG and MGC.

Hari

BlankHi,

This is Sundar from Future Software. I am currently designing Testsuites for
IUA(RFC3057).

In Section 4.1.1 of RFC 3057, there is a statement as below:
4.1.1 Q.921 or Q.931 primitives procedures

On receiving these primitives from the local layer, the IUA layer

will send the corresponding QPTM message (Data, Unit Data, Establish,

Release) to its peer. While doing so, the IUA layer needs to fill

various fields of the common and specific headers correctly. In

addition the message needs to be sent on the SCTP stream that

corresponds to the D channel (Interface Identifier).

Now my question is what is the relationship between the D-channel and the
SCTP streams.

Best Regards,
Sundar.
I'm not here just to make a living, I'm here to make a difference !
