APC-1321 "Coordinating H.323 and T.120 Conferences"
by Bill Quinn 04 Sep '97

04 Sep '97

Hello everyone, APC-1321.ZIP (a zipped word 7 file) was cross posted last night to the following FTP servers: ftp://ftp.imtc-files.org/imtc-site/t120_sunriver97/ (Q3 site) ftp://itu-t:sg15!avc@ftp.gctech.co.jp/9709_Sun/ (Q14 site) ftp://standard.pictel.com/avc-site/9709_Sun/ (Q14 mirror site) The document discusses several short term issues which have been identified by the IMTC ad-hoc T.120/H.323 Harmonization group. The document covers the recommended coordination of T.120 and H.323 conferences. Replacement text for H.323, H.245 and T.120 is included. While this document has already been endorsed by several companies, it is important to mention that Lucent will be presenting a document that solves one of the issues in a different way. Note that APC-1321 will address many issues, and the Lucent document will only conflict with one of these issues. We feel that since both solutions solve an existing problem differently, that we would rather present both solutions and let the experts of Q3 and Q14 make the final group decision. Thanks, bill quinn ---------------------------------------------------------------------------- ---- Bill Quinn DataBeam Corporation VOICE : 606-425-3695 EMAIL : billq(a)databeam.com

MF (multifrequency) tones are, as far as I can tell, used only for in-band trunk signalling, such as on international circuits (Signalling System No. 5) and between PBXes and COs. They use a combination of two tones from the set of 700, 900, 1100, 1300, 1500, and 1700 Hz. See Recommendation Q.151 for how they're used in SS5 to encode digits and control signals. I've not identified a need for MF signals to be carried over H.32x terminals, but maybe Dale or someone else has. >> 1.

A newer version of a >Recommendation can augment and clarify but cannot constrain previous >versions. But a new version of a recommendation CAN add new mandatory requirements on terminals claiming compliance to that new version. For example, if "X" was optional in Version 1, version 2 could make "X" mandatory for terminals claiming compliance to version 2. Or, if "X" was mandatory in version 1, and version 2 specifies an improved technique "XX", version 2 could require that two version 2 terminals communicating with each other use "XX" instead of "X" even though both implement "X" for backward compatibility with version 1. A new version should always require backward compatibility by continuing to mandate fallback to mechanisms required in previous versions. -- Toby ___________________________________________________________ Toby Nixon, Program Manager - NetMeeting http://www.microsoft.com/netmeeting Microsoft Corporation, Applications and Internet Client Group, Redmond WA USA +1 (425) 936-2792 Fax: +1 (425) 936-7329 mailto:tnixon@microsoft.com

APC-1285 - Use of H.245 in Supplementary Services - posted
by Pete Cordell 02 Sep '97

02 Sep '97

Dear All, APC-1285 - Use of H.245 in Supplementary Services - has been posted to the FTP site. A number of details have been changed since earlier drafts, but the principle is the same. The tone is also changed to encompass third party call control in general rather than just supplementary services. The abstract is as follows: A major issue in H.323 is that if a remote party does not support a particular supplementary service that you wish to use then you will not be able to use it, even if you yourself support it. This is particularly important when a remote endpoint calls into a managed signalling environment where supplementary services are supported. Currently, if the endpoint that is calling in does not support supplementary services, then it will be impossible to keep track of a call while transferring the endpoint to another endpoint within the environment. What is required is for the gatekeeper to perform some form of third party call control. This is an fundamental element of call control and needs to be supported in H.323. This proposal suggests making use of H.245 empty capability sets to implement this. The proposal also allows for the signalling of remote hold, which is useful in its own right.
