TITLE : REPORT ON THE STATUS OF Q.12/16 "B-ISDN MULTIMEDIA
SYSTEMS AND TERMINALS"
---------------------
1. Interim activities
After the SG16 meeting in March 1997, Q.12/16 held two
Rapporteur meetings jointly with Q.13/16 and Q.14/16:
- 10 - 13 June 1997, in Hertzlia (Israel), hosted by
RADVision and Vocaltec
- 8-11 September 1997, in Sunriver (USA), hosted by Intel
After the Sunriver meeting, Q.12/16 work has been carried out
through correspondence.
2. Progress of the work
The progress of Q.12/16 work is summarized in the following

-------------------------------------------------------------
* Security for broadband systems address ATM specific
considerations; generic specifications are covered by
H.235.
The major work items toward determination of H.310 Version 2
and H.bmultipoint are listed as follows:
H.310 Version 2
- Reflection of H.310 Implementers Guide
- Reflection of corrected H.320/H.321 interoperation mode
stack of RAST-5 terminals
- Inclusion of procedures for intercommunication between
H.310 RAST-1 and RAST-5 terminals
- Reflection of the advice from SG11 regarding the use of B-
HLI for resourceId indication.
H.bmultipoint
- Reflection of the Sunriver meeting discussion outcome
- Inclusion of basic communication procedures using H.245
control and H.310 VFS C&I for the video switching and video
mixing multipoint
- Discussion of clocking issues
- Review of the call setup procedures in the light of point-
to-multipoint configuration
These and other items need be further reviewed and discussed
at this meeting.
3. Objectives of this meeting
- Decision of H.222.0|ISO/IEC 13818-1 Amendments 3 and 4
- Decision of H.321 Version 2
- Approval of H.310 Correction
- Determination of H.310 Version 2
- Determination of H.bmultipoint
- Determination of H.222.0|ISO/IEC 13818-1 Amendment 5
- Discussion on security, VBR and interworking aspects
- Production of liaison statements to relevant groups
- Discussion on future direction
4. Particular items needing the guidance of WP2
1) Forward referencing to the SG11 definition
H.321 Version 2 relies on SG11 definition of new signalling
capabilities:
- Section 7.3"End Station Identifier" in Q.2941.1 GIT
- Section C.4parameter "X"in a Q.2931 Notification
Indicator IE
At the time of decision of H.321 Version 2, they are under
development in SG11. A possible solution will be to issue
Implementers Guide of H.321 when SG11 has completed these
works.
2) Future direction of standardizing ATM-based audiovisual
communication systems
H.310 Version 2 and H.bmultipoint will provide the basic set
of specifications for the ATM-based audiovisual communication
systems. The next step target should be set as part of the
future H-series workplan with cosideration of the current
level of interest in the ATM-based systems.
