        Dear Colleagues,

        I would like to invite you to participate in an audio call, Tuesday
October
        20th from 11AM to 1PM EST to discuss our work plan for the study of
gateway
        decomposition as outlined in TD 89 (WP2).

        The goals of the audio call will be to identify what work items we
need to
        completed and in what order should we attack them. Once we have an
agreed to
        work plan, we can talk about building an architecture document and
the
        specific requirements of each interface.

        As a place to start the discussions, I think we need the following
        (referenced to TD 89):

        New Protocols:
        *****************
        Interface A - Device Control Interface

        New H.246 Annexes:
        ************************
        1) H.323 to Voice/Voiceband Terminals = The breakdown of the media.
How DTMF
        is converted to/from UserInputIndication messages, etc. (There is a
draft of
        this in the current H.246 Annex B)
        2) H.323 to SS7 (Similar to Q.699 - a Q.931 to ISUP conversion spec)
        3) H.323 to Q.931 (Similar to the section in Annex A for H.320)

        Interface B, C, D
        ********************
        For the Proposed Interfaces B, C, and D. Given that the messages
passing
        across these interfaces must reflect all of the content of the
signaling
        that the respective signaling functions receive from and send to
extern
        entities, aren't these protocols modified or extended ISUP for
Interface D,
        modified or extended Q.931 for Interface C, and modified or extended
H.225
        for Interface B? For C & D, can they be the real protocols if
carried on a
        T1 and some derivation of them if running over TCP/IP?

        Please try and get all attendee requests in by Monday the 19th at
12:00 Noon
        EST so that I can make the proper arrangements. I will send port
assignments
        later that day. Here is a summary of attendees so far:

        1) G. Thom
        2) S. Nayak
        3) R. Badri
        4) P Kallur
        5) K. Hedayat
        6) R Spitzer
