[Fwd: SGCP+IPDC => MGCP]
by Hong Liu 20 Oct '98

20 Oct '98

Hi, all, I would like to inform you on the most recent development in converging SGCP and IPDC for IP device control. The merged protocol is called MGCP (or media gateway control protocol). This is an important step towards the realization of gateway decomposition for VoIP. I hope this will help the new work item within SG 16 on the same issue. Best regards, --Hong

Please include me in the call, Guido Schuster 1 847 222 2486 guido_schuster(a)3com.com Mark Reid <mreid(a)VIDEOSERVER.COM> on 10/16/98 03:52:34 PM Please respond to Mailing list for parties associated with ITU-T Study Group 16 <ITU-SG16(a)MAILBAG.INTEL.COM> To: ITU-SG16(a)MAILBAG.INTEL.COM cc: (Guido Schuster/MW/US/3Com) Subject: 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 7) R Chopra 8) A Amir 9) R Even 10) H Liu 11) J Yeh 12) R Radhika 13) B Bell 14) T Taylor 15) G Freundlich 16) M Reid/B Hill/G Kajos All comments welcome, Mark Reid 1-781-505-2368 mreid(a)videoserver.com Bryan Hill 1-781-505-2159 bhill(a)videoserver.com

(781) 505-2159 bhill(a)videoserver.com <mailto:bhill@videoserver.com> -----Original Message----- From: Mark Reid [SMTP:mreid@VIDEOSERVER.COM] Sent: Friday, October 16, 1998 4:53 PM To: ITU-SG16(a)mailbag.cps.intel.com Subject: 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 7) R Chopra 8) A Amir 9) R Even 10) H Liu 11) J Yeh 12) R Radhika 13) B Bell 14) T Taylor 15) G Freundlich 16) M Reid/B Hill/G Kajos All comments welcome, Mark Reid 1-781-505-2368 mreid(a)videoserver.com Bryan Hill 1-781-505-2159 bhill(a)videoserver.com

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 7) R Chopra 8) A Amir 9) R Even 10) H Liu 11) J Yeh 12) R Radhika 13) B Bell 14) T Taylor 15) G Freundlich 16) M Reid/B Hill/G Kajos All comments welcome, Mark Reid 1-781-505-2368 mreid(a)videoserver.com Bryan Hill 1-781-505-2159 bhill(a)videoserver.com

[Q] Differences between 'ad hoc multipoint conf' and 'multipoint conf'.
by Lee Hyoung soo 16 Oct '98

16 Oct '98

Hi, Can you tell me the differences between 'ad hoc multipoint conference' and 'multipoint conference'? According to the recommendation of H.323 V2, ad hoc multipoint conference : An Ad Hoc Multipoint conference was a point-to-point conference that had been expanded into a multipoint conference at some time during the call. multipoint conference : A Multipoint conference is a conference between three or more terminals. Any multipoint conference can begin with three or more terminals without expansion from point-to-point conference? Best wishes, soo Nada Research Co., Ltd. Korea.
