About a month after CableLabs shared results from certification wave 20, the industry's R&D house gave a belated passing grade to Cisco Systems' uBR7246 cable modem termination system for DOCSIS 1.1 qualification.
The nod puts Cisco in elite company. Arris Group is the only other vendor thus far to obtain the DOCSIS 1.1 qualification green light.
The event was far from unique. CableLabs has qualified and certified equipment weeks after the end of testing waves, and most recently handed out a late DOCSIS 1.0 qualification to Pacific Broadband Communications, which was recently acquired by Juniper Networks. Still, the late green light marks the first one involving DOCSIS 1.1 qualification.
John Mattson, director of marketing for Cisco's cable business unit, said there were a few anomalies and "phantom failures" in the initial test results involving the uBR7246, a CMTS/router with redundant capabilities. Those problems did not resurface during retesting, Mattson said.
On the market for more than two years, Cisco's uBR7246 is also qualified for DOCSIS 1.0.
Cisco has submitted its full-chassis uBR10012 for DOCSIS 1.1 testing in wave 21, slated to end March 22.
