Title:	Harmonization of ITU-T C&I and DSM-CC
Purpose:	Proposal
Relevant sub-group: DSM

-----------------------------------

At the ITU-T Experts Group sole sessions held on November 1, 3 and 4 in Singapore, we discussed the C&I (Control and Indication) signalling in the context of protocol reference model of the H.32X audiovisual terminal and its relevance to DSM-CC Extension.  One of the issues is through what channel these signals are transported and with what protocol stack.  The following is the outcome of the meeting.

We will provide the commands and procedures for:

•	Terminal capability exchange,
•	Mode setting (initiation and switching),
•	Video frame synchronous and asynchronous signalling, particularly for conversational services.

We wish to collaborate in:

•	ATM specific procedures for distributive/retrieval services,
•	Video frame synchronous/asynchronous signalling for distributive/retrieval services.
