Docsis 3.0 Gear Tracker

4:30 PM -- CableLabs recently posted the results of Docsis Certification Wave 67, and there's not exactly much new to write home about.

That's because many of latest Docsis 3.0 approvals were for re-certifications of cable modems and embedded multimedia terminal adapters (E-MTAs). However, the results did reveal a new wideband product from Ubee Interactive (formerly Ambit) -- the DDW3600.

Per usual, the CableLabs posting offers skimpy details about these certified products, but Ubee VP of business development Barry Hardek tells me via email that it's a Docsis 3.0 wireless gateway that supports four bonded channels in each direction (the bare minimum required by the specs), plus built-in 802.11n.

Also important: The product is based on Texas Instruments Inc. (NYSE: TXN) silicon. Ubee has also won certification for a standalone modem based on the TI platform, along with two that use a Broadcom Corp. (Nasdaq: BRCM) chipset that can bond up to eight downstream channels. (See Broadcom Breaks Docsis 3.0 Barrier .)

Newbee from Ubee

Ubee's latest certified wideband box is powered by the TI chipset.

In the latest Wave, CableLabs also awarded recerts to the Arris Group Inc. (Nasdaq: ARRS) TM702G EMTA and WBM750A modem; the Motorola Inc. (NYSE: MOT) SB6120 modem; and the SMC Networks Inc. SMCD3G Docsis modem gateway. Nothing new on the cable modem termination system (CMTS) front so far, meaning Casa Systems Inc. remains the only supplier to win qualification for a CMTS that can do upstream channel bonding.

In non-Docsis 3.0 news of note, CableLabs did "verify for interoperability" a digital set-top from Pace Micro Technology that uses Docsis 2.0 and the Docsis Set-Top Gateway (DSG), a data and headend signaling path that supplants proprietary methods used by Motorola and Cisco Systems Inc. (Nasdaq: CSCO) and is a key piece of the tru2way platform. The box in question is the Pace RNG110, a lower-end, all-digital device that's part of Comcast Corp. (Nasdaq: CMCSA, CMCSK)'s next-gen set-top project.

Shifting back to wideband, here's our most updated list of Docsis 3.0 certified and qualified products:
