Harmonic has announced another business win for its CableOs product, with the virtualized cable access solution deployed with DSA, a nonprofit antenna association in Denmark.

The software product will be managed by Harmonic’s local CableOS partner, Infowise.

Earlier this week, Harmonic attributed a 14% spike in Q3 sales to CableOS, which it said is now deployed with 19 cable operators globally.

"Harmonic's CableOS solution will ensure our smooth transition to DOCSIS 3.1, allowing us to efficiently and cost-effectively increase broadband capacity through a flexible architecture to support the deployment of R-PHY in the future,” said Henrik Lindholm, chairman of DSA, in a statement.

"As operators around the world move to DOCSIS 3.1 and roll out Gigabit internet offerings, it's becoming obvious that choosing a software-based CMTS offers distinct advantages over hardware, including operational efficiency, accelerated introduction of new features and scalability," said Gil Katz, senior VP of cable access business operations at Harmonic. "Our CableOS offering features a unique virtualized architecture that empowers cable providers like DSA to deliver fast broadband speeds and significantly reduce their operating expenses."

The Dynamic Spectrum Alliance said Cisco has now joined its ranks, along with Swarm Technologies and UTStarcom.

“The DSA is looking forward to working with Cisco Systems, Swarm Technologies and UTStarcom as we continue to work with governments and regulators around the world to enable more efficient spectrum utilization that will bring better connectivity and promote social and economic inclusion," said DSA chairman Paul Garnett.

As the name advertises, the group, whose members already include Amazon, Facebook, Google, Microsoft and Comcast, has been pushing for more "dynamic" access to "unused" spectrum over traditional market mechanisms like band clearing and auctions, but has been pushing back on the C-Band alliance proposal for clearing and private-market deals over auctions, deals that would lock up spectrum for licensed use rather than more flexible, unlicensed, uses.

"The private sale option raises significant concerns about fairness and efficiency, which the DSA does not believe can be cured by Commission oversight of a private sale," the DSA told the commission in comments on the C-Band proposal. "First, the DSA does not believe that a private sale can provide any assurance or confidence to C-band users, or the public that relies upon their services’ future availability, reliability, or costs. Second, a private sale will not protect the interests of all parties who are interested in acquiring C-band spectrum for flexible use, or the interests of the public in ensuring the sale is conducted in a manner that ensures a competitive market going forward. Third, a private sale would guarantee that U.S. taxpayers would not see any money from the auction of this public asset."

Cable operators and broadcasters are among those incumbents who would be hurt by interference in the band because they use that satellite spectrum for delivery of network programming (broadcast) and programming networks (cable) to stations and cable systems.
