CableLabs Awards Industry ‘First’ With DOCSIS 3.0 Qualification
LOUISVILLE, Colo –BUSINESS WIRE– Dec 19, `07 — In a major milestone for the cable industry, CableLabs has awarded qualification status for Data over Cable Service Interface Specification (DOCSIS) 3.0.
DOCSIS 3.0 specifications enable downstream data rates of 160 Mbps or higher and upstream data rates of 120 Mbps or higher.
Casa Systems received “silver” qualification while Arris and Cisco received “bronze” qualification for their cable modem termination systems (CMTS) headend gear. The announcement comes at the conclusion of the recent test wave in which the first products built based on the DOCSIS 3.0 specifications were formally evaluated.
The headends were tested under a tiered program that was created as a way to encourage CMTS makers to submit gear for testing earlier than they otherwise might. CableLabs also offered suppliers numerous informal interoperability events where vendors work together in CableLabs’ facilities to test and evaluate their implementations of the specifications.
“This technological achievement is a great step for our industry,” said Brian L. Roberts, Chairman and CEO of Comcast Corp., and Chairman of the CableLabs Board of Directors. “CableLabs rapid certification effort will enable companies to begin to develop products that will support the rapid deployment of DOCSIS 3.0 services in 2008.”
To achieve these higher data rates DOCSIS 3.0 describes a methodology for channel bonding in both the upstream and downstream directions. A minimum of four channels, each with throughput of 40 Mbps, is specified. DOCSIS 3.0 also incorporates support for the Internet Protocol version 6 (IPv6).
IPv6 is the next generation of the Internet Protocol and greatly expands the number of Internet addresses that cable operators may use, allowing them to provide consumers with more IP-based services. In addition, DOCSIS 3.0 is backward compatible with all existing DOCSIS products.
IPv6 also will allow cable operators to effectively manage the proliferation of devices that are capturing consumer interest, including portable media players, cellular phones, gaming consoles, PDAs and others. More at CableLabs.
