DOCUMENT #:GSC15-PLEN-51 FOR:Presentation SOURCE:ITU AGENDA ITEM:Plenary 6.10 Conformance and Interoperability Testing Reinhard Scholl ITU Global Standards Collaboration (GSC) GSC-15

Highlight of Current Activities (1/3)  ITU-T SG 11: Lead study group on test specifications  ITU-T SG 15: Has extensive testing ecosystem  ITU-T SG 16: its IPTV standards (H-series) was put to test in ITU-T’s first interop event (20-23 July) 3 IPTV testing specs approved; others further developed  ITU-T SG 17: Lead study group on languages and description techniques Also: Q14/17 on Testing methodology, specification language and Generic test suites for CIT 2

Highlight of Current Activities (2/3)  ITU-T JCA-CIT: Joint Coordination Activity on Conformance and Interoperability Testing Works with all Study Groups to:  address the topics relevant to conformance and interoperability testing  enhance the quality of ITU-T Recommendations Eliminate errors, ambiguities unverified behaviours Include sufficient detail for implementation and testing Include interfaces needed for interconnection and testing  develop methodologies and frameworks for testing 3

Highlight of Current Activities (3/3)  Regional ITU consultations on conformance assessment and interoperability Quito, 8 July 2010 Nairobi, July 2010 Sydney, Sep  Pilot conformity database developed  ITU Interop started IPTV (July in Geneva; Sep. in Singapore; Dec. in India) Home networking 4

Strategic Direction  WTSA-08 Res. 76 on conformance & interop  …supported & complemented by WTDC-10 Res. 47 (ITU-D)  ITU Council-09 mandated a pilot conformity assessment database interoperability events human resources capacity building assistance in the establishment of test facilities in developing countries a business plan for long-term implementation 5

Challenges  Regional ITU consultations on conformance assessment and interoperability are a useful discussion platform, see e.g. Presentations at Kenya workshop, in particularPresentations at Kenya workshop  TSB’s overview presentation on status of implementation of WTSA-08 Res. 76overview presentation 6

Next Steps/Actions  Continue implementing steps outlined under “Strategic directions”  Study groups to continue working on test specs  Keep momentum of ITU’s IPTV Interop event Expand to other ITU standards, in collaboration with partners as appropriate  Populate conformance database 7
