CableLabs said it handed out passing grades to eight cable modems and nine cable modem termination systems for the complex DOCSIS 1.1 specification following certification wave 22.

With those additional stamps of approval, CableLabs has certified a total of 32 modems for DOCSIS 1.1, a specification that adds quality of service and other elements that underlie cable's forthcoming PacketCable platform, which is expected to usher in new multimedia services and applications based on Internet protocol, including IP telephony.

CableLabs said the latest modem vendors to get the DOCSIS 1.1 green light include 3Com, Correlant, Joohong and Motorola. Texas Instruments and Toshiba, meanwhile, had cable modems re-certified for the specification.

Certification was significant for Motorola, a leading DOCSIS cable modem vendor that had yet to break through the DOCSIS 1.1 barrier. In the most recent wave, CableLabs certified three Motorola cable modem models: the SurfBoard 4100, SB4200 and SB4220.

CableLabs also qualified or re-qualified CMTSs from ADC, Arris, Cisco, Juniper, Motorola and Scientific-Atlanta, which re-sells Juniper's CMTS under the "Prisma" brand. In some cases, vendors had more than on product qualified, CableLabs said. Louisville, Colo.-based CableLabs has qualified 16 CMTSs overall.

In comparison, CableLabs has certified 214 modems and qualified 28 CMTSs for DOCSIS 1.0.

"Our fourth year promised to be the most productive for DOCSIS," said Rouzbeh Yassini, the founder and CEO of YAS Broadband Ventures and senior executive consultant to CableLabs.

CableLabs is expected to kick off certification wave 23 on July 22, with results expected on or around Sept. 26. The final wave of 2002 is slated to begin Oct. 14.
