Vendors make initial run at DOCSIS 2.0, CableHome 1.0

Sat, 11/30/2002 - 7:00pm

The launch of certification wave 24 at CableLabs shaped up to be a bellwether of sorts, as several vendors stepped forward to become the first to submit products for official testing on DOCSIS 2.0, CableHome 1.0 and PacketCable 1.0.

On the DOCSIS 2.0 front, Motorola Broadband, Scientific-Atlanta, Terayon Communication Systems, Texas Instruments and Xrosstech all submitted cable modems or reference designs based on the advanced specification.

Com21 Inc. and Terayon were also the first to submit cable modem termination systems for official testing on DOCSIS 2.0, a spec that beefs up cable's upstream and mitigates noise.

For CableHome 1.0, a specification that extends DOCSIS to devices on a home network, two vendors submitted DOCSIS 1.1-based residential gateways for official certification: Linksys Group Inc. and NetGear Inc.

Several manufacturers also submitted multimedia terminal adapters (MTAs) to CableLabs for concurrent DOCSIS 1.1 and PacketCable 1.0 testing. Those vendors included Arris, Terayon, Motorola Broadband, Toshiba America Information Systems and Scientific-Atlanta. CableLabs also received CMTSs from Cisco Systems, Motorola Broadband and Terayon for official PacketCable testing.

For PacketCable–a platform that will usher in QoS-sensitive packet-based cable services such as IP telephony–the submission of MTAs and CMTSs to CableLabs for official testing marks just the beginning. A spate of additional network elements will make-up the full PacketCable architecture, including call management servers, provisioning servers, media gateways, signaling gateways and media gateway controllers.

Certification wave 24 is slated to end on December 13, with results released on or around December 19. The first CableLabs certification wave of 2003 is scheduled to kick off January 27, and end on April 4. CW 26 is slated to begin May 12.
