Broadband Forum Gfast Certified Interoperable Products

Certified pairs by similarity where not directly tested, but use the same Gfast chipset and firmware as a previously certified device from the same manufacturer, and the change in hardware or system software is not expected to impact ability of the system to pass certification testing. Refer to the Gfast Certification Guidelines for additional details.

• All certified device pairs must pass a baseline set of tests, covering mandatory functionality for performance, stability, functionality (SRA, FRA, PSD conformance, etc.)
• Additional capabilities that may be tested include: support for multiple lines (i.e. vectoring), dying gasp, and discontinuous operation. These features are listed in addition to the Baseline case
• Some devices are certified due their similarity to a previously tested device. Devices certified through similarity include the reference to the primary device's certification ID
