> 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
