DOCSIS 2.0 Approved as International Standard.Business Editors/High-Tech Writers LOUISVILLE, Colo.--(BUSINESS WIRE)--Dec. 19, 2002 The ITU-T See ITU. ITU-T - International Telecommunications Union (International Telecommunications Union See ITU. (body, standard) International Telecommunications Union - (ITU) ITU-T, the telecommunication standardisation sector of ITU, is responsible for making technical recommendations about telephone and data (including fax) communications systems for PTTs and suppliers. -- Telecommunication Sector) has announced the approval of a standard defining the second-generation data over cable system, also known as DOCSIS (Data Over Cable Service Interface Specification) A cable modem standard from the CableLabs research consortium (www.cablelabs.com), which provides equipment certification for interoperability. (TM) 2.0. The completion of the Recommendation J.122 represents a major milestone in the development of the broadband infrastructure worldwide. The award-winning technology gives cable operators the ability to offer speeds up to 600 times faster than are available through standard dial-up telephone modems. DOCSIS (Data over Cable Service Interface Specification (communications, networking) Data Over Cable Service Interface Specification - (DOCSIS) ITU-approved interface requirements for cable modems involved in high-speed data distribution over a cable television network. ) technology has been specified by CableLabs. DOCSIS 2.0 is the latest member of the DOCSIS family. Separately today, CableLabs(R) announced that it has awarded certification status for DOCSIS 2.0 compliance during the recently completed round of certification testing. Dr. Richard R. Green, Chairman of the relevant ITU-T Study Group 9 and President and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of CableLabs, stated: "DOCSIS is recognized as a technology that enables the broadband revolution to reach communities and that will help sustain economic development. ITU's fast action enables cable operators around the world to provide consumers and bandwidth users with a faster, more powerful version of that technology." Rouzbeh Yassini Rouzbeh Yassini is an Iranian-American engineer, self-credited with creating the cable modem and helped propel broadband through cable. He was the founder of LANcity and helped establish the cable modem industry standard (DOCSIS) through Cable Television Laboratories. , executive consultant to CableLabs and head of its Broadband Access See broadband and wireless broadband. initiative, said: "DOCSIS is a great enabler. We have seen more than 20 million DOCSIS modems shipped to nearly every continent. Our colleagues in Europe and Asia have played a major role in this globalization globalization Process by which the experience of everyday life, marked by the diffusion of commodities and ideas, is becoming standardized around the world. Factors that have contributed to globalization include increasingly sophisticated communications and transportation of DOCSIS technology," added Yassini. "Cable modem cable modem Modem used to convert analog data signals to digital form and vise versa, for transmission or receipt over cable television lines, especially for connecting to the Internet. prices have plummeted because of DOCSIS and it is the basis for an exciting array of new Internet See Web 2.0 and Internet2. Protocol-based consumer and business services that cable operators will deliver," he said. The new international standard is a key to unleashing the significant bandwidth available in cable systems, and is backward compatible with previous versions of the DOCSIS. Furthermore, as is true with the previous version of the specification (ITU-T Rec. J.112, also known as DOCSIS 1.1), the new standard can be used as the foundation upon which IPCablecom IP-communication/telephony services can be offered. The standardization is remarkable due to the fact that work on the specification began less than 18 months ago. The rapid standardization is important to promoting worldwide adoption of this important technology. The enhancements that J.122 provides over J.112 are primarily focused on the upstream transmission path, from the customer to the network. The new standard provides significantly increased capacity and improved robustness to the upstream path allowing cable operators to make maximum use of their existing infrastructure. The specification includes two technologies that achieve that goal: an advanced form of time-division multiple access, and synchronous code-division multiple access. CableLabs is a research and development consortium of cable television system operators representing cable operators internationally. CableLabs plans and funds research and development projects that will help cable companies take advantage of future opportunities and meet future challenges in the cable television industry. It also transfers relevant technologies to member companies and to the industry.
