1. I have no idea what the user-data component is used for.
2. I don't know what you mean by "get and set," but RAS does not use Q.931
or UUIEs in its encoding. It uses ASN.1 PER exclusively. I assume by your
other question that you are asking what the outer-most encoding is for RAS.
With call-signaling, it's Q.931; with RAS, it's ASN.1 PER--RAS uses ASN.1

Subject: How to get the heel of RAS Message.
I have two problems concerning H.323 ASN.1.
H.323 ASN.1 states as follows:
protocol-discriminator INTEGER (0..255),
user-information OCTET STRING (SIZE(1..131)),
My question is," What's the use of "user-date" field and what its
protocol-discriminator field stand for? " Can anyone present me an example?
The H.323 ASN.1 tells us that following the path
"H323-UserInformation>>h323-uu-pdu>>h323-message-body", we can get and set
UUIE of Q931 messages. But how can we do the same thing with RAS messages?
Or, what are the "ABSOLUTE PATH", the root, of the messages?
