VIAVI DAA Test-Ready Certification Program

Are You Ready To Maintain Your Remote PHY Plant? We Are!

Distributed access architectures (DAA) like Remote PHY are coming fast, and operators globally are keenly aware that their implementation can be disruptive to HFC maintenance practices if not properly planned. VIAVI anticipated this challenge, and in partnership with leading DAA vendors, has developed a standards-based upstream ingress remediation and return sweep solution enabling reuse of existing ONX field meters, XPERTrak software, and operational processes. This solution requires that the DAA vendors implement CableLabs-specified NDF/NDR capabilities to operate, and the timing of this implementation varies among vendors.

VIAVI frequently receives inquiries from operators asking which DAA vendors currently support these solutions or have plans to support, and to simplify these responses the VIAVI DAA Test-Ready Certification Program was established.


Participating DAA vendors are certified at one of two levels:

Gold Certification

  • DAA partner has demonstrated interoperability with VIAVI instruments and systems to perform end-to-end return sweep and upstream spectrum analysis
  • Gold-Certified Vendors:  Casa SystemsCiscoHarmonicTeleste, Vecima

Silver Certification

  • Vendor has engaged with VIAVI and has roadmap in place to support interoperable sweep/ingress solution
  • Silver-Certified Vendors:  Arris, BKTelNokia

VIAVI will continue to update vendor status as they progress, all questions regarding anticipated dates for specific vendors to support VIAVI DAA test capabilities should be directed to the respective DAA vendors.
