Interoperability

We are dedicated to the ongoing advancement of real-time, rich-media communications, and promote the interoperability of products and services based on international industry standards.

While we actively promote standardization, The IMTC is not a standards development organizations, but rather an Interoperability testing & recommendation forum.

Our members participate in standards-related activities, interoperability forums, workshops and labs throughout the year and submit their test findings and specifications for consideration in developing Standards and Recommendations.

IMTC collaborates with numerous standard bodies, including ETSI, IEEE, IETF, ISO/IEC, ITU-T, TIA, 3GPP, and W3C.

Industry Standards

The IMTC has been involved in the development of four sets of ITU-T communications protocols:

H.320, H.323, H.324 (3G-324 M for cellular mobile systems) and T.120. Since 2000, the IMTC has focused increased attention on Packet-Switched Streaming, based on the 3GPP Technical Specifications TS 26.233 and TS 26.234. Interworking between H.323 and SIP products has also come to the forefront.

Standards Organizations

ETSI

http://www.etsi.org

ETSI (the European Telecommunications Standards Institute), formed in 1988 by the Commission of the European Communities, is a non-profit organization whose mission is to produce the telecommunications standards that will be used for decades to come throughout Europe and beyond. Based in Sophia-Antipolis in France, ETSI unites 786 members from 56 countries and represents administrations, network operators, manufacturers, service providers, research institutions and end-users. The members determine the Institute’s work program, and are responsible for approving its deliverables. As a result, ETSI’s activities address accurate market requirements conveyed by its members.

IMTC has conducted several interoperability sessions jointly with ETSI.

IEEE

http://www.ieee.org

The Institute of Electrical and Electronics Engineers, Inc. (IEEE, pronounced Eye-triple-E) is a non-profit, technical professional association of more than 380,000 individual members in 150 countries.

Through its members, the IEEE is a leading authority in technical areas ranging from computer engineering, biomedical technology and telecommunications, to electric power, aerospace and consumer electronics, among others. Although not a formal standards organization, the IEEE sponsors consensus-based standards activities which have led to the development of nearly 900 active standards with 700 more under way.

IETF

http://www.ietf.org

The Internet Engineering Task Force is a large open international community of network designers, operators, vendors, and researchers concerned with the evolution of the Internet architecture and the smooth operation of the Internet. It is open to any interested individual.

The actual technical work of the IETF is conducted in work groups, which are organized by topic into several areas (e.g., routing, transport, security, etc.). Much of the work is handled via mailing lists. The IETF holds meetings three times per year.

In support of IETF, the IMTC has, over the past several years, conducted extensive interoperability testing on the protocols subtending H.323, such as IP, RTC and UDP. More recently, IMTC has organized interoperability sessions to verify interworking between H.323 and SIP-based solutions.

ISO/IEC

http://www.iso.org

The International Standards Organization is the source of ISO 9000 and more than 14,000 International Standards for business, government and society.

ISO is network of national standards institutes from 147 countries working in partnership with international organizations, governments, industry, business and consumer representatives. A bridge between public and private sectors.

IMTC has participated in establishing requirements for the ISO/IEC JTC 1/SC29 Working Group, more widely known as MPEG, which stands for “Moving Picture Experts Group”. This acronym also designates a family of ISO/ IEC JTC1 standards used for coding audiovisual information (e.g., movies, video, music) in a digital compressed format.

ITU-T

http://www.itu.int/net/home/index.aspx

The International Telecommunications Union (ITU) is a treaty organization of the United Nations which has as members each and every country. It is also the oldest telecommunications standards organization, dating back to 1865. The standards work in the ITU is divided into two sections, ITU-Telecommunications (ITU-T) and ITU-Radiocommunications (ITU-R). Each section is organized into Study Groups, Working Parties, and Questions. The work in a Question is led by a Rapporteur.

IMTC, as a formal and approved liaison to ITU Study Groups 15 (Transport networks, systems and equipment) and 16 (Multimedia services, systems and terminals), has played a significant role in helping define, shape and promote the rapid ratification of standards for multimedia communications. In particular, IMTC has been specifying requirements in the areas of Intellectual Property Rights, H.323 protocols, and speech/video codecs.

In addition, IMTC holds industry events, enabling providers to test interworking among various developers’ implementations of standards-based equipment.

TIA

http://www.tiaonline.org/

The Telecommunications Industry Association (TIA) represents providers of communications and information technology products and services for the global marketplace. Its core competencies include standards development, advocacy, market development and trade promotion activities.

3GPP

http://www.3gpp.org

The 3rd Generation Partnership Project (3GPP) is a collaboration agreement. It brings together a number of telecommunications standards bodies which are organizational partners. The current organizational partners are ARIB, CCSA, ETSI, T1, TTA, and TTC.

Established in 1998, the original scope of 3GPP was to produce globally applicable Technical Specifications and Technical Reports for a 3rd Generation Mobile System based on evolved GSM core networks and the radio access technologies that they support. It was subsequently extended to include the maintenance and development of the Global System for Mobile communication (GSM) Technical Specifications and Technical Reports including evolved radio access technologies (e.g. General Packet Radio Service (GPRS) and Enhanced Data rates for GSM Evolution (EDGE).

IMTC has become extremely active in organizing sessions to verify interoperability among different su’?? Packet-Switched Streaming (PSS) products for use in the mobile environment. These products are built in compliance with 3GPP Technical Specifications TS 26.233 and TS 26.234.

W3C

http://www.w3.org

The World Wide Web Consortium (W3C) “develops interoperable technologies (specifications, guidelines, software, and tools) to lead the Web to its full potential as a forum for information, commerce, communication, and collective understanding”.

SIP

http://www.ietf.org/html.charters/sip-charter.html

http://www.sipforum.org

IETF has chartered the Session Initiation Protocol (SIP) working group to continue the development of SIP, currently specified as proposed standard RFC 2543. SIP is a text-based protocol, similar to HTTP and SMTP, for initiating interactive communication sessions between users. Such sessions include voice, video, chat, interactive games, and virtual reality. The primary focus of the group involves bringing SIP from proposed to draft standard, in addition to specifying and developing proposed extensions that arise out of strong requirements.
