CableLabs® Certifies More DOCSIS™ 1.1 Modems
Total of 21 1.1 Modems Certified to dateLouisville, Colorado, March 28, 2002—The cable industry has certified twelve more DOCSIS™ 1.1 high-speed cable modems at the conclusion of the third certification wave for DOCSIS 1.1 testing, adding to a growing supply of second-generation interoperable high-speed devices.
The companies receiving DOCSIS 1.1 certification status in the latest wave of testing are Accton, Arris, Askey, Conexant, Quanta Network Systems Inc., Samsung, Scientific-Atlanta, Tellabs, Terayon, Thomson, and Xrostech.
In addition to this record number of certified DOCSIS 1.1 CMs, CableLabs® today qualified two Cable Modem Termination Systems (CMTSs) from Arris and Riverstone.
The 1.1 modems are compatible with existing DOCSIS 1.0 equipment and will work on cable systems alongside modems that will be certified under future versions of DOCSIS. There are now a total of 21 DOCSIS 1.1 modems certified, and four CMTSs that are qualified.
Strategically, DOCSIS 1.1 opens a technological doorway to augmented revenue streams for cable providers. It does so by enabling the existence of high-speed Internet service tiers, via techniques known as data fragmentation and quality-of-service (QoS). Those two techniques allow cable providers to deliver high-speed Internet services simultaneously over the same plant—and in a path parallel to—core video services.
And, perhaps most importantly, equipment built to comply with the DOCSIS 1.1 specification becomes the foundation for expanding the list of advanced cable services offered by cable providers, including home networking through the CableLabs CableHome™ project, and packet telephony and multimedia services through the CableLabs PacketCable™ project. Overall, DOCSIS 1.1 enables cable operators to deliver twice the level of functionality while reducing operating costs by half.
To date, 203 DOCSIS 1.0 modems have received certification status and 26 CMTS have been qualified by CableLabs. In this wave, 7 cable modems from the following companies achieved 1.0 certification or re-certification, in some cases for new products: Aastra, Asustek, Linksys, Motorola, and Thomson.
Rouzbeh Yassini, executive consultant to CableLabs and leader of the cable modem initiative at CableLabs, said that the DOCSIS 1.1 results of certification wave 21 indicate that the cable modem certification strategy continues to help the broadband industry's advance as DOCSIS 1.1 is the basis for new IP services rollouts. "This certification program continues as a vehicle for helping get product to market in a remarkable timeframe and in good working order," said Yassini, who also is CEO of YAS Broadband Ventures.
