Widening the door for advanced cable-based services and applications such as packetized voice, two cable modem manufacturers and two cable termination system vendors today became the first to pass CableLabs' test for the DOCSIS 1.1 specification.

Following a revamped effort for automated testing routines and an "ongoing" wave of DOCSIS 1.1 testing that kicked off in January of this year, CableLabs said it concluded certification wave 19 by handing out passing grades to Toshiba's 2500 cable modem model, Texas Instruments Inc.'s cable modem reference design and CMTS gear from Arris Group Inc. and Cadant Inc.

Other vendors that submitted equipment for DOCSIS 1.1 certification and qualification in the most recent wave included 3Com, Ambit Microsystems, Askey, Cisco Systems Inc., Conexant Systems, Ericsson, Tellabs, Joohong, Motorola Broadband Communications Sector, Samsung, Terayon, Thomson Consumer Electronics, ADC Telecommunications, RiverDelta Networks (now part of Motorola Broadband) and Riverstone Networks.

CableLabs noted that the certified 1.1 modems are compatible with existing DOCSIS 1.0 equipment and will be compatible with future versions of the spec, including DOCSIS 2.0, which is designed to mitigate noise and widen cable's upstream pipe.

Among other advancements, DOCSIS 1.1 provides the underlying quality of service platform for CableLabs' PacketCable infrastructure and CableHome initiative.

"Our customers will be the real beneficiaries because they will be able to enjoy ever more advanced and affordable broadband technologies in their homes or businesses," said Joseph Collins, chairman of CableLabs' board of directors, in a statement. Collins also is chairman of AOL Time Warner Inc.'s new interactive-video division, and is the former CEO of Time Warner Cable. (Editor's note: Collins will be inducted into The Cable Television Hall of Fame, it was announced today.)

Certification wave 20 is slated to kick off on Oct. 22, with results released on or around Dec. 21, according to CableLabs' most recent certification schedule.

Perhaps surprisingly, it took 28 months for CableLabs to go from specification to certification for the more advanced 1.1 spec. In comparison, it took a period of 33 months for that to happen for DOCSIS 1.0.

CableLabs said it also ended certification wave 19 by stamping approvals on 29 modems and one CMTS (from Motorola) for DOCSIS 1.0. Overall, CableLabs has certified 178 modems and 24 CMTSs for DOCSIS 1.0.
