Certification wave 28 at CableLabs ended with a home networking milestone: granting the first passing grade to a cable modem gateway based on the CableHome 1.1 specification.

Receiving that honor was Linksys (now part of Cisco Systems), which was awarded the CableHome 1.1 stamp for its Wireless-G Cable Gateway (WCG200), which has 802.11g support baked in. CableLabs tested two other products for CableHome 1.1 in wave 28, but did not disclose those vendors.

A step above CableHome 1.0, the 1.1 spec enables cable operators to offer managed home networking services and features, including firewalls, parental controls and some preliminary LAN-side messaging. It also serves as a foundation for multimedia applications delivered via a home network.

Those additive features are "a great addition to our home networking businesses," said Richard Hertz, CableHome's certification board chair and vice president of cross platform network services at Comcast Cable.

During the wave, CableLabs also awarded CableHome 1.0 certification to a gateway from Motorola Broadband.

On the PacketCable 1.0 front, three vendors won approval: ARRIS for its Touchstone Telephony Modem 402P embedded multimedia terminal adapter, Siemens Carrier Networks for its SURPASS hiQ call management server (CMS), and Nortel Networks for the media gateway controller function of its Succession Communication Server 2000.

With Siemens in the qualified mix, the number of CMSs to win PacketCable qualification rises to six. The other vendors in that rare air include Syndeo Corp., Cedar Point Communications, Cisco Systems, Nortel Networks and Telcordia Technologies.

A flow of modems also made it through DOCSIS testing unscathed. CableLabs granted DOCSIS 2.0 certification to eight modems and one eMTA, and re-certified two other modems for the advanced spec.

Ambit Microsystems, Askey Computer Corp., Castlenet, Shenzhen Coship, Motorola Broadband (three models) and Thomson were awarded DOCSIS 2.0 status. ARRIS' Touchstone Telephony Modem 402P eMTA also received DOCSIS 2.0 certification.

Castlenet and Motorola also had products re-certified for 2.0.

CableLabs also awarded DOCSIS 1.1 certification to products from Electroline Equipment Inc. and Toshiba (two modems). Thomson also received DOCSIS 1.0 certification on a model during the wave.

Electroline's certification is significant because its product is designed for outdoor use. The company's "DOCSIS Rugged Cable Modem" is designed to enable operators to perform DOCSIS network monitoring in conditions that would break modems designed for indoor, consumer use.

"This represents another chapter in the success of the DOCSIS platform, as cable operators begin to use the same DOCSIS infrastructure for network reliability as for high-speed data service delivery," said Jay Rolls, DOCSIS certification board chair and vice president, telephony and data engineering for Cox Communications.

Terayon Communication Systems made it through another testing wave as the only cable modem termination system vendor to win DOCSIS 2.0 qualification.

CableLabs is expected to release results from certification wave 29 in late June.
