We are building the future of the XCCF right now, so it’s a great time to get involved.
#BEST CABLE MODEMS FOR 2018 SERIES#
If you want to learn more about the XCCF, you can read the previous entry in our PNM blog series here, or access the public version of the architecture document here. The CMVA, one of those applications, uses the data provided by the XCCF to validate modem performance in support of PNM.

We need to make sure these PNM capabilities work as intended in systems before we deploy and assure we can take full advantage of the capabilities once deployed. This complexity is why having PNM within the DOCSIS specification is an important move for the industry, supporting its ability to evolve. DOCSIS is a sophisticated system, especially 3.1 and Full Duplex DOCSIS.
You need to design it into the system as early as possible for the lowest cost, or work it in later at a much higher cost. You can’t add in reliability as if it’s a separate feature. You can’t manage what you can’t measure, so having modems capable of reporting PNM measurements allows cable operators to manage their networks effectively, inexpensively, and reliably! Realize: It’s always too late to start thinking about reliability! Therefore, we can build best practice operation solutions on that strong foundation. Best practices we can share: With a consistent industry approach to PNM data reporting, collection, and certification testing of modems, everyone can validate and verify consistent reporting.It is a critical first step toward many possible futures for DOCSIS. This capability can become an important source of information for all sorts of planning and engineering activities. Getting ready for future technology evolutions: New DOCSIS 3.1 modems provide more information about the plant and its ability to support enhanced services and deploy new technologies like FDX.A consistent approach with CMs is the first step toward CMTS testing and having integrated PNM capabilities for the entire architecture. PNM capabilities are an important part of this needed improvement. Ideally, a new technology will cost less to build, be less expensive to maintain, and provide superior service. We never want to introduce a new technology that costs more to maintain than the previous. Continuous service improvement: Before deploying a technology, it is important to know ahead of time whether CMs will be capable of supporting network maintenance and troubleshooting.Why is it important to validate PNM data reporting from CMs? But it’s an important step, and one we wish to highlight. Validating CM PNM functionality for DOCSIS 3.1 network deployments might seem like a small step in a large technology life cycle. CableLabs built the cable modem validation application (CMVA) to help bring that assurance to the industry. When CMs can be assured to report data about impairments in the network, service providers have a tool for finding and fixing network issues before they impact service. Cable modem (CM) validation is the work to assure that the CMs can fully support PNM. This blog entry in our PNM series focuses on cable modem validation.
CableLabs supports that commitment through its work in specifications, and particularly through its PNM project. When the cable industry made proactive network maintenance (PNM) a part of the DOCSIS® specifications, we showed great commitment to service. The cable industry is always trying to find ways to improve service.
