“Interoperable standardized Gfast technology is key because it underpins an ability to deliver next generation ultrafast broadband at scale,” said Kevin Foster, General Manager, Architecture and Innovation for BT. “Certification to the Broadband Forum’s Gfast requirements provides a known level of confidence and will reduce test time for both network operators and their communication provider customers.”

Lincoln Lavoie, Senior Engineer, Broadband Technologies at UNH-IOL, said: “The certification represents an outstanding technical achievement with hundreds of rigorous tests of the stability, functionality, control, and performance of Gfast systems and thousands of hours of close technical collaboration over many months between the lab and all of the companies involved. The program’s certification of these products has played a significant role in understanding and improving the implementation of Gfast.”

Approved Test Laboratory (ATL) Program

The Broadband Forum Approved Test Laboratory (ATL) program was established to benefit the industry by having independent, yet vetted, test laboratories, enabling vendors and operators to choose test labs with a heightened level of confidence that the labs have the right competence.

These labs specialize in their given areas, are well versed in the Broadband Forum specifications and help drive the BBF's goals for multi-vendor interoperable technologies, testing agreed performance and functional measurements to help expedite deployments.

Home Networking Related Testing (G.hn)

The ITU developed G.hn as the first global home networking standard created to unify home networking services and devices over any wire, including coaxial cable, phone lines and power lines. The HomeGrid Forum and the Broadband Forum are working together to develop an interoperability program to verify the adherence to the ITU standard. The Broadband Forum's role is to lead the development of the test requirements documents and test plan to be used in the HomeGrid's formal Compliance and Interoperability program.

Various plugfests are taking place and are driven by vendor interest and the industry's desire to test first silicon and to demonstrate G.hn's market potential. The specific goals of these first G.hn plugfests are to perform early tests for interoperability and compliance of chipsets from a number of vendors, validate the test suite and act as a prelude to the launch of HomeGrid's formal Compliance and Interoperability program.
