CableLabs said nine new cable modems made the grade for DOCSIS 1.1 following certification wave 23, increasing the number of 1.1-certified modems to 42.

CableLabs also has qualified a total of 18 cable modem termination systems (CMTS) for DOCSIS 1.1 thus far, including qualification during the most recent wave of Terayon Communication Systems' BW 3500, a CMTS powered by silicon made by Terayon spin-off Imedia Semiconductor.

Following the most recent wave, which concluded Sept. 20, CableLabs handed out the coveted 1.1-certified label to modems made by Arris, Askey, Belkin, Castlenet, Fujitsu, Hitron, Linksys and Thomson, which makes RCA-branded cable modems. Com21 Inc. also received 1.1 re-certification for its DOXport 1110XB model.

Equipment based on the QoS-sensitive DOCSIS 1.1 specification will serve as the underpinnings of PacketCable, a platform that will usher in advanced packet-based cable applications and services such as IP telephony.

As part of wave 23, CableLabs said it concurrently performed three "parallel practice" certification runs for gear based on CableHome 1.0, PacketCable 1.0 and DOCSIS 2.0, an advanced specification designed to triple cable's upstream data path. CableLabs said results from the practice run will be used to refine products that eventually will be submitted for official certification waves based on those specifications.

On the DOCSIS 1.0 front, chip giant Broadcom Corp. said two cable modems based on its new DOCSIS 2.0-based silicon were certified following wave 23. That chip, the BCM3348, supports both of DOCSIS 2.0's advanced physical layer schemes: A-TDMA (advanced time division multiple access) and S-CDMA (synchronous code division multiple access).

CableLabs is expected to kick off certification wave 24 on Oct. 14, and release results on or around Dec. 19. The organization in August announced plans to lower some testing fees and to simplify and streamline its testing processes by combining its DOCSIS certification tests with those tied to PacketCable and CableHome.

CableLabs also got the green light from the DOCSIS board on Aug. 14 to move ahead on "eDOCSIS," a new specification effort tied to broadband equipment with "embedded" DOCSIS capabilities such as set-tops and residential gateways.
