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.
