Gfast Test Plans

This Broadband Forum Test Plan, TP-337, provides a set of functional, stability, and basic performance test cases and related pass/fail requirements for G.fast implementations according to ITU-T Recommendations G.9700 [1] and G.9701 [2].

The primary goal of TP-337 is to provide a set of test cases and framework to verify interoperability between a G.fast Transceiver Unit at the Optical Network Unit (FTU-O) (e.g., a Distribution Point Unit [DPU]) and one or more FTU at the Remote site (FTU-Rs) (e.g., Customer Premise Equipments [CPEs]).

TP-337 serves as the test plan, including pass/fail requirements for each test case, for the Broadband Forum G.fast Certification Program. Technical content in this test plan includes test setup information, equipment configuration requirements, test procedures, and pass/fail requirements for each test case.

For additional details about the G.fast Certification Program, including requirements for participation in the program or to view the list of currently certified devices, , please refer to: Gfast Interoperability and Certification Testing.

Issue 3 of the test plan adds additional test cases for iDTA, cDTA, and SHINE Type 4 noise.

The primary goal of IR-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 IR-337 serves as the test plan, including pass/fail requirements for each test case, for the Broadband Forum Gfast Certification Program. Additional documentation is available from the Broadband Forum about the Gfast Certification Program, including program benefits, participation requirements, number and type of equipment to be tested against, and logo usage guidelines.
