SAN RAMON, California (August 22, 2000) --The International Multimedia Telecommunications Consortium (IMTC) today reported that the SuperConnection test session of more than 65 multiple-protocol endpoints and components in a single conference was one of the highlights during the fourth annual IMTC SuperOp! Event held in Nice, France from July 9-15. The successful IMTC SuperOp! Event gave manufacturers, which are IMTC members, an opportunity to test the interoperability of their current and emerging multimedia conferencing and telephony products or services across a variety of Internet, intranet, LAN/WAN, digital (ISDN) and analog (POTS) telephone networks. IMTC SuperOp! achieved several objectives that support the IMTC's goal to foster the development and production of multimedia and telecom products and systems that operate in a seamless, multi-vendor network and are easy to install, use and maintain.

The SuperConnection test session was a single mixed conference that included audio only, video and audio as well as full video, audio and data connections. During the successful test more than 25 H.323 endpoints, nine H.323 gatekeepers, seven H.323 gateways, five H.323 MCUs (Multipoint Control Unit), 18 H.320 endpoints, three H.320 MCUs and one SIP gateway and one SIP endpoint were connected in the SuperConnection conference.

A number of new interoperability and compatibility tests were also conducted at IMTC SuperOp!, including the first series of tests using the Session Initiation Protocol (SIP). According to Greg W. Meyer, Chair of the IMTC's Conferencing over IP (CoIP) Activity Group and IP Telephony Program Manager at Intel Corporation, "Six companies with eight test teams were testing SIP including one firm with a H.323 gateway." The CoIP Activity Group conducted the tests.

The six-day SuperOp! Event drew more than 57 companies and a total of 260 participants from 17 countries who joined together in some 99 test teams that focused testing on interoperability of diverse, multimedia conferencing and telephony products and services built around such international standards as H.323, European Telecommunications Standards Institute (ETSI) TIPHON (Telecommunications and Internet Protocol Harmonization Over Networks), SIP, T.120, H.324 and H.320. IMTC SuperOp! 2000 was sponsored by ETSI, Intel, Microsoft and Tenovis with additional support from France Telecom. The seventh annual TAPI Bake-off, which is the Windows Telephony Interoperability Testing event, was co-located at the IMTC SuperOp! Event. Nineteen companies participated in the test sessions that promote interoperability between hardware and software programs that use the Windows Telephony Applications Programming Interface (TAPI).

At the IMTC SuperOp! event the teams tested much of the functionality of H.323, including FastStart and H.245 tunneling, gatekeeper-to-gatekeeper (intradomain) dialog and H.323 to phones and H.320 gateways. Some manufacturers also tested fax over IP (FoIP) and security features (H.235 and H.323 Annex J).

"The IMTC's SuperOp! Event continues to be the ultimate, international proving ground for standards-based multimedia and telephony products, said Matt Collier, president of the IMTC and the vice president of global business development at Polycom, Inc. "Engineers from around the world pool their expertise to develop comprehensive test procedures that are used at the IMTC SuperOp! and throughout the year at other IMTC tests. Work conducted at IMTC SuperOp! is driving voice/video/data convergence by providing rigorous testing platforms that truly measure interoperability betweenproducts from different sources and across multiple protocol networks."

In order to maintain an open forum for evaluation, discussion and resolution, individual test results are not disclosed. This enables competing companies to share important information and data that would normally be proprietary and confidential, for the benefit of the entire industry.

Conducting testing under the auspices of the IMTC provides the only vendor-neutral environment for companies to pinpoint areas where differing interpretations of any ambiguities in the international communications standards may exist. Since 1996, the IMTC has hosted more than 40 interoperability events around the globe to test T.120, H.320, H.323 and H.324 products and services for compatibility with each other.
