CableLabs Remote MACPHY Project Launches

CableLabs Admin

Feb 7, 2018

Last month, we announced the launch of the Remote MACPHY working group. As part of our Distributed CCAP Architecture program (DCA), the Remote MACPHY working group is comprised of operators, equipment manufacturers, and CableLabs’ engineers that help cable operators distribute their access networks. The charter is to develop one or more specifications that allow vendors’ Remote MACPHY solutions to interoperate when deployed.

Remote MACPHY Background

The cable industry has been working on replacing the old Cable Modem Termination Systems (CMTSs) with a Converged Cable Access Platform (CCAP) for some time. CCAP hardware simplifies the network by putting ports for both data and cable video on a single device, saving space and power. Now that operators have transitioned to CCAP, there has been a movement to distribute those functions out of the headened, closer to the edge of the network. This is being done through Remote MACPHY and Remote PHY. These Distributed Access Architectures provide several key benefits to the Hybrid Fiber Coax (HFC) networks that deliver cable TV and broadband and we highlight Remote MACPHY in our video below. 

Watch now to learn more about Remote MACPHY technology and its benefits.

DOCSIS 3.1: Where We Are Today

The NCTA recently announced Gigasphere, which encompasses the new experiences customers will come to enjoy based on the DOCSIS 3.1 technology developed by CableLabs, Inc.

There is a lot of excitement around DOCSIS 3.1, and the new capabilities it will bring to cable networks for cable operators and their customers. Customers will be able to enjoy gigabit speed access on the downstream and upstream, allowing them to download 4K video and ultra-high definition movies faster than ever. Reduced network delay will also take the online gaming experience to a new height, increasing responsiveness and allowing higher resolution graphics. Also, the widespread availability of cable high-speed internet will make the benefits of DOCSIS 3.1 available to over  90% of U.S. households.

Cable service providers, in addition to being able to provide richer experiences to their customers, will have an easier time maintaining their networks due to the Proactive Network Maintenance functionalities embedded into DOCSIS 3.1; thus being able to provide a more consistent and reliable experience to their customers.

Looking back, it has been just over 18 months of intense work, collaboration and innovation across technology vendors and MSOs since we started the DOCSIS 3.1 project, reaching our first public milestone in November 2013 by publishing the first official release of the DOCSIS 3.1 specification – and we are not done yet! We are planning for our first round of equipment interoperability testing later this year, and we expect to see devices ready for certification by the middle of 2015.

Also, CableLabs is working with several MSOs to to make sure the networks are ready when DOCSIS 3.1 devices hit the market. We are engaged in a wide range of HFC network testing activities to prime the network to support the higher capacities enabled by DOCSIS 3.1.

Finally, to increase the ecosystem technical expertise around DOCSIS 3.1, CableLabs will be hosting a DOCSIS 3.1 training session June 2- June 5  for attendees to gain an in-depth understanding of DOCSIS 3.1.

These are exciting times at CableLabs, so much has been accomplished, and there is much more to look forward to!

Stay tuned for further updates ....
