ID-337 provides a set of functional, stability, and basic performance test cases and related pass/fail requirements for FAST implementations according to ITU-T Recommendations G.9700 and G.9701. Test cases include requirements for vectoring, where applicable. The primary goal of ID-337 is to provide a set of test cases and framework to verify interoperability between an FTU-O (e.g., a DPU or a DP-side Reference Design) and one or more FTU-Rs (e.g. CPEs or CP-side Reference Designs). The test cases are defined for a Device Under Test (DUT – either a DPU or CPE), tested against a Link Partner (either a CPE or DPU respectively). The DPU/CPE may be a reference design, however containing the necessary FTU?O/R and system functionality to execute this test plan (see e.g., section 4.2). Issue 1 of ID-337 serves as the test plan, including pass/fail requirements for each test case, for the Broadband Forum FAST Certification Program. Additional documentation is available from the Broadband Forum about the FAST Certification Program, including program benefits, participation requirements, number and type of equipment to be tested against, and logo usage guidelines. For additional details about the Broadband Forum’s certification programs, please refer to: Interoperability and Certification Testing.
This test plan is currently under heavy development within the Broadband Forum and is not yet available for active testing.
