Hi Christian,
Good timing, In the study D meeting in Washington dc I was asked to put my contribution as a proposal for new annex in h.246. In the contribution I show one example in Annex-A of the RAS messages mapping into ITU INAP other example may include HLR/VLR, MAP and WIN messages. I did not include the parameters mapping. Because, I did not want to do all that work until the concept is approved. (document attached)
In any case I have proposed the lower layer sigtran transport (CTP) to carry upper layer protocol for tunneling and interworking. Which should not be any issue with h.246 or the work you are doing..I hope?
I will read your contribution as a framework going forward on SS7 interworking. We both/all need to resolve the Transport problem where to terminate the Lower SS7 layers (MTP 1,2,3).
That is, where does SS7 ends and IP begins? in the H.323 network i.e., tiphon.
Regards, Ed

G'Day All,
Attached is a draft copy of H.246 Annex C.
As you can see it is Version 0.0 so it needs some work. It is based on Q.699 as is split into 4 main sections:
1 Overview/Introduction 2 ISUP to H225 message and parameter mapping 3 Outgoing Call - H.225 to ISUP Basic Call Services 4 Incoming Call - ISUP to H.225 Basic Call Services
The services sections need some work to align with the 3pty/conference discussions.
RAS hasn't been considered in the document yet.
Comments/addition/amendments welcome.
Regards, Christian Groves
