Interop·Labs for DOCSIS® 4.0 Technology
On behalf of CableLabs, Kyrio will be hosting upcoming DOCSIS 4.0 interoperability events!
As vendors work to create the development of DOCSIS 4.0 products, CableLabs and Kyrio are busy preparing for the next phase of technology development: conducting interoperability events. CableLabs has established a rigorous process for technology development starting with DOCSIS 1.0 technology and ultimately leading to the robust ecosystem that exists today. The company’s proven approach has worked successfully at CableLabs for the past 24 years:
Phase 1 Phase 2 Phase 3
Phase 1 is the specification stage, when CableLabs, members and vendors come together to collaborate on defining the DOCSIS technology. Phase 1 for DOCSIS 4.0 was completed in 2019, when the specifications were written and suppliers have began implementation.
Phase 2 is when interoperability events (aka interops) occur at CableLabs in Louisville, Colorado to make sure that systems work together. As the term implies, interops are held to ensure that components of a DOCSIS system — including the base technology, security and support — are interoperable for easy installation and proactive customer care.
For DOCSIS 4.0 technology, CableLabs will be prepared to host the first interop event this year after SCTE Cable-Tec Expo 2021 in Atlanta, where the show floor promises to hold several DOCSIS 4.0 technology demonstrations.
At this time, 12 DOCSIS 4.0 interoperability events are planned to begin in October 2021 and will run through December 2022. This near-monthly spacing will give suppliers the opportunity to attend, learn and then run a sprint to add new functionality for the next interop.
The early interops focus on basic functionality of the DOCSIS chipsets. As the schedule progresses, the focus will shift to adding more software functionality. Always, the emphasis will be on interoperable solutions, including the cable modem, cable modem termination system (CMTS) and software support systems. Going forward, the interops will include Remote PHY and Remote MACPHY devices.
Interoperability gives operators the confidence to plan large installations and the certainty that the equipment they purchase today will also work tomorrow. Customers can buy a modem and take it with them if they move into a new cable territory, worldwide. Interoperability provides a larger market in which suppliers can compete, which, in turn, allows for healthier ecosystems and varying strategies.
Phase 3, the certification stage, will happen naturally as the interoperability process produces more mature products and systems. We’ll talk more about this phase when that time approaches.
The interop phase can be a fun, invigorating time. Some of us have been working on the DOCSIS project for two decades, and there are always new entrants. As we shift back to working in our offices post-pandemic, we’re all looking forward working face-to-face in the lab—all in the effort to bring forward the next generation of cable broadband and deliver on the 10G promise.
Interoperability is paramount to the DOCSIS ecosystem. The DOCSIS community is encouraged to once again come together for these upcoming interoperability events, contributing and collaborating to keep the DOCSIS 4.0 ecosystem healthy and sustainable. This fall, CableLabs will be ready!
Medical Grade Connectivity: How IoT Drives Digital Transformation in Healthcare
The connected world that is enabling the digital transformation of our lives and society is pervasive. So often, people view the radical transitions as dehumanizing – that technology moving us further from each other, making our relationships more distant and our interactions impersonal. However, this really doesn’t hold up to close scrutiny when we consider the context of our whole lives. We’ve never been so connected to people and information – and we are becoming more engaged every day. We are able to stay in touch with family and friends more easily; share experiences even though distant; share intimate ideas over phones even when sitting next to each other. Like so many important areas of our lives, the realization of the connected world is also transforming healthcare. CableLabs hosted an Inform[ED] symposium to investigate how connected healthcare is evolving and what technical challenges it must overcome. Attended by a fantastic mix of technical professionals, visionaries, and subject matter experts, the overwhelming consensus was that emerging technologies and pervasive networking will reinvent healthcare. The result will be an even more humane and caring system, accessible to more and more people at even lower cost.
The connected healthcare event was opened by Simon Kos, Chief Medical Officer of Microsoft. He set the tone for the day, demonstrating how technology is fundamentally changing society as it becomes more accessible, affordable and capable. His view was on our total health – not just during episodic care with clinicians, but our overall quality of life as we cope with the challenges of living. To organize his storytelling, he used the Quadruple Aim framework and presented examples to examine technology innovation along the dimensions of engaging patients, empowering care teams, optimizing clinical and operational effectiveness and transforming the care continuum. His examples resonated with the views and ideas of other presenters and panelists throughout the day.
Transforming Healthcare Through Interoperability and Data Liquidity
Security concerns are very real, as discussed by a panel of Corporate Information Security Officers (CISOs) moderated by Ram Ramadoss of Catholic Health Initiatives. Panelists included Cyrus Malbari of Abbott, Kathy Hughes of Northwell Health, and Timothy Torres of Sutter Health. The rash of ransomware incidents against thousands of hospitals globally demonstrates the severity of the threat environment. Yet, as Mr. Ramadoss discussed with his panel, they can’t control threats. Rather they work to control weaknesses. Some weaknesses are obvious and yet have been very hard to fully mitigate – phishing, being too open with system administrator privileges, exposing sensitive systems to risks by using them for personal activities such as email. Others are not so obvious. Kathy Hughes pointed out that the focus on care tends to decentralize IT – with the result that a large percentage of devices connected to the care network may not even be known to security teams. Timothy Torres said one way his organization found that works to deal with this challenge was to incentivize purchasing devices through correct channels. The panelists all felt that device security certification could be a major improvement in ensuring securable devices were used to provide care. And they cited potential savings in cyber security insurance as a result.
A discussion point that was visited throughout the day was data liquidity. The concept of data liquidity is not synonymous with interoperability, though related. Rather, data liquidity is about ensuring actionable access to health information by whomever needs it. This is a differentiating challenge in healthcare. As Kerry McDermott and Jeff Smith highlighted in the legal and regulatory panel, medical devices are regulated by a plethora of federal agencies. No other industry has the same mix of privacy and security requirements while at the same the ability to produce such rich and valuable data that, applied to the right algorithms and made available to the right person at the right time can save lives while lowering costs.
Fireside Chat with Ed Cantwell
Ed Cantwell and Ed Miller, both from the Center for Medical Interoperability, observed that interoperability and security in connected devices are interdependent. Security functions between devices must be interoperable, and insecure connectivity doesn’t provide practical interoperability. Ed Cantwell went further, describing secure interoperability need to be approached as a utility – a fundamental capability that must exist to support evolving practices in health care. This idea was similar to ideas shared during the IoT Security Inform[ED], where Brian Scriber of CableLabs asserted that code and practices to secure IoT devices and systems should be developed collaboratively and then shared freely.
Ed Cantwell also shared that he thinks blockchain technologies have a role to play here. Blockchains are designed to address trust in a way directly applicable to healthcare, providing a basis for security, privacy, control, transparency, and compliance.
Innovation in Connected Healthcare
The final speakers painted a bright future, discussing in depth how digital transformation will refocus healthcare on the patient, humanizing care. Summer Knight of Firecracker was particularly eloquent, sharing her passion and drive to show how the cable industry can be pivotal in providing medical grade connectivity. She feels that the evolving connectivity will engage and empower individuals and their family as part of the healthcare team as we hardwire humanity at every point of care. Medical grade connectivity can provide the platform for customer engagement and activation, putting the patient in the center of all decisions. The opportunity for contribution from cable is significant. Remote monitoring can reduce costs by as much as $8400/year per patient. Coupled with other critical functions, the near term opportunity for cable operators is over $200 billion annually, supporting a total addressable market of over 170 million people.
This was a very informative event. It brought stakeholders together to chart how we can achieve a bright future in providing secure, connected health. Working together, the cable industry and health care industry can lower the per capital cost of care and we can improve the wellness of populations by making access easier. Medical grade connectivity will improve the patent experience and change how we assess success in providing care as we transition the business focus from fee-for-service to a focus on positive results. We can empower care teams in new ways, ensuring quicker care that allows us to treat patients better and increase the likelihood of excellent outcomes.
Cable Connects with Healthcare
The connection between cable and healthcare may not be immediately obvious to the casual observer. However, upon further reflection, this connection becomes more evident. Cable companies have been expanding their commercial services to focus on the healthcare vertical. Cable operators are able to deliver a cost-effective bundle of broadband, telephone, and television services that meet the connectivity and business needs of hospitals and clinics. Connected healthcare is very important for areas of the country that lack medical resources. For example, GCI, the largest Internet provider in Alaska, is taking a lead in connected healthcare by providing remote Alaskan villages with telemedicine through their ConnectedMD program.
Connecting hospitals and clinics is only the beginning. Remote patient monitoring is becoming an increasingly important aspect in addressing the growing costs of healthcare. The results of a year-long remote patient monitoring pilot from Geneia showed a savings of over $8,000 per monitored patient annually. This kind of remote patient monitoring relies on a robust broadband connection to the home.
Today, in addition to connecting hospitals and clinics, the cable network infrastructure reaches 93% of U.S. homes. This enables cable services to contribute in an increasingly important role toward healthcare.
The demand for healthcare services continues to grow thanks to the reality of an increasing demographic of individuals over the age of sixty-five: currently that group makes up 15% of our population, but by 2040 it will be nearly 22%. Coupled with the rising cost of providing healthcare services in hospitals, connected healthcare makes more sense and “cents” than ever. It is well known that treating chronic conditions comprises the highest percentage (as much as 80%) of U.S. healthcare expenditures. Using remote patient monitoring to stay on top of chronic conditions and anticipating potential crises avoids unnecessary ER visits and improves patient outcomes.
Connectivity transcends industries and the issues faced by healthcare are massive, therefore the time for collaboration has arrived. One example of this kind of collaboration with the healthcare industry is our work with the Center for Medical Interoperability (CMI). The West Health Institute study, The Value Of Medical Device Interoperability, estimated that more than $30 billion in annual health care savings could be realized by solving medical device interoperability. CMI was formed to address this problem and is modeled after the CableLabs centralized research and development laboratory. CableLabs brings its expertise in device interoperability, device security, and certification to the healthcare industry through its participation in CMI’s specification development efforts.
Another example of industry-wide collaboration is our participation in the Open Connectivity Foundation (OCF) which is spearheading network security and interoperability standards for IoT devices. CableLabs not only has a board position at OCF, we chair the OCF Security Working group. Through OCF, we are working to drive increased IoT security to address the associated risks to both the network as well as the privacy of subscribers.
The organization that I represent, CableLabs, recognizes the increased role that the cable industry will contribute to the healthcare industry of the future. We are producing two back-to-back Inform[ED] Conferences to bring together cable industry technologists with health information management professionals. April 12 will focus on IoT Security and April 13 will cover Connected Healthcare. Please join us in New York City and we look forward to having you join us in this important conversation.

DOCSIS 3.1 Technology: Spec to Product in One Year
Around this time last year, CableLabs kicked off the first DOCSIS® 3.1 interoperability event. Looking back, it is amazing how far we have come.
Over the last year, CableLabs has held seven DOCSIS 3.1 interoperability events that provide manufacturers with the opportunity to work together on interoperability, development, and compliance. A total of 27 vendors across cable modem, head-end, and test equipment manufacturers have participated so far. Over the course of these events, vendors have continued to demonstrate improvements in product maturity.
Additionally, CableLabs has completed seven dry run events which provided vendors with additional development opportunities and evaluation of product readiness for certification and field trials through joint test execution between CableLabs and the vendors. This progress has paved the way for CableLabs to officially open the door for device certification submission and for cable operators to plan their field trials. While we can’t say much about what is going on in our certification labs, we can say it is like a beehive in there! CableLabs will be continuing the interoperability and dry run events in 2016 to support the industry and accelerate device availability.
One of the highlights of the year was the DOCSIS 3.1 technology demonstration day, where vendors flexed their muscles and showed the potential of the DOCSIS 3.1 technology. Demonstrations showcased the multi-Gbps capabilities of DOCSIS 3.1 technology, even while the products were still in development stage. Also, the ability to deploy DOCSIS 3.1 services in today’s networks through a fluid transition was demonstrated. Some vendors even showed how some of today’s cable modem termination systems, which are already deployed in the field, can be upgraded to support DOCSIS 3.1 technology while simultaneously supporting DOCSIS 3.1 and DOCSIS 3.0 devices. The state of the art in spectral efficiency was showcased with the support of 4096 QAM which is a 50% increase from what is possible in today’s DOCSIS 3.0 networks. All indicators are pointing in the right direction that DOCSIS 3.1 technology, as promised, will enable the cable operator to deliver great user experience to the customer.
In addition to holding several training workshops, CableLabs has been working closely with SCTE and NCTI to develop the required training courses to educate and prepare the workforce for the deployment of DOCSIS 3.1 services.
And as the year comes to an end, Comcast puts the icing on the cake by announcing the kickoff of their DOCSIS 3.1 field trials signaling that their customers will soon be enjoying the great experiences that can be offered by DOCSIS 3.1 technology. Congratulations to Comcast for such a big achievement, and ending the year on a high note for the industry and for its customers as a whole.
