  1. Voice on the Net Conference IMTC Efforts to Support and Encourage Interoperability! Interoperability to Ubiquity Data Video Audio Matt Collier President IMTC Vice President, Polycom

  2. The Agenda • Standards Definition • Standards Organizations • IMTC Activity Update • IMTC Voice over IP Forum

  3. Standards or standards? • Adopted Standards vs Market standards • Are “free” applications free? • Who benefits from open standards • Do Standards stiffle competition? • Do Standards freeze innovation? Standards Key? Aren’t communications products that don’t communicate BROKEN?!?

  4. Who Sets the Standards?

  5. ITU - Setting Multimedia Communications Standards • Developing interoperable open standards for multimedia communications for > 10 years • Focused on real-time conversational services • Addresses multiple levels: • Audio and video encoding • Data protocols • Network interfaces and protocols • Call setup and management • Multinetwork Interworking Whose Standards?

  6. T.120/130 - Series also T.100s, T.170s T.504, T.523, T.541, T.564 V. - Series (almost all) All H. - Series G.720 - Series also G.190s, G.ACG, G.WSC/A, G.WSC/B, G.4kbps F.700 - Series New for ‘97: Study Group 16, The Lead Study Group for Multimedia Whose Standards? http://www.itu.ch

  7. The Alphabet Soup • ITU-T Video Conferencing Standards • H.320: For ISDN widely used today • H.321: H.320 over ATM • H.322: H.320 over iso-ethernet LANs • H.323: Multimedia conferencing on Packet Nets • H.324: Multimedia conferencing on POTS • H.310: Multimedia conferencing on ATM • ITU-T T.120 Data Conferencing Standards • Work with/without all the H.series • Multipoint multinetwork collaboration

  9. Other Standards Organizations • ETSI - European Telecom Standards • IETF - Internet Standards • ANSI - North American Telecom Standards • IMTC supports all efforts to adopt telecommunication standards worldwide!

  10. International Multimedia Teleconferencing Consortium • Non-profit 501 (c) (6) California corporation organized as a business league • Incorporated Oct. 1993, as CATS • Open Membership Policy • Controlled by Voting Members

  11. International Multimedia Teleconferencing Consortium Promote, Encourage, and Facilitate the Ongoing Development and Implementation of Interoperable Multimedia Teleconferencing Solutions based on Open International Standards.

  12. International Multimedia Teleconferencing Consortium • A open forum of over 148 vendors and service providers working to make open standards work • Actively supports standards development • Providing a vendor neutral forum for interoperability testing: H.320, H.323, H.324 and T.120 - all on-going now • Close liaison relationships with ITU-T, ETSI and IETF • http://www.imtc.org Whose Standards?
