DOCSIS 3.1® Certification Testing: A Look at Core and Secondary Testing

In our latest webinar, Kyrio explained new changes that accelerate DOCSIS 3.1 certification testing. If you missed the webinar, you can watch the replay or view the slides. Additionally, you can read our frequently asked questions document related to these recent changes.

We also announced that we are implementing a new two-phase test strategy that allows us to find critical issues sooner in the certification wave and make the process more consistent. The new two-phase approach begins on July 14, 2017, and consists of Core and Secondary Testing.

The following diagram outlines the new two-phase test strategy:

So, what exactly are Core and Secondary Tests?

The Core Testing phase includes a set of critical tests that oftentimes prevents devices from being certified. After a device passes Core tests, the device moves on to Secondary Testing. If there are any failures during Core Testing, we will notify the submitting company, as well as provide an opportunity to update their submission. Through this new two-phase testing strategy, we will be able to identify critical failures sooner in the testing cycle to ensure a better customer experience.

In the Secondary Testing stage, we will be diligent in informing submitting companies of any errors that might be discovered. This new process lets us reliably predict the time necessary to complete certification testing.
