ARRIS to Demonstrate DOCSIS 3.1 Capabilities at CableLabs

This week, we’re at CableLabs® DOCSIS 3.1 Technology Demonstration Event to give service providers insight into managing the DOCSIS® 3.1 migration.

Our presentation will cover DOCSIS 3.1’s facility for backwards compatibility and scalability to tomorrow’s networks. Specifically, we’ll be demonstrating the following aspects of the technology:

  • How the ARRIS E6000™ CER platform and CMTS product support bonding across DOCSIS 3.0 and DOCSIS 3.1 downstream channels
  • How a DOCSIS 3.0 upstream channel can simultaneously support DOCSIS 3.1 and DOCSIS 3.0 cable modems

We will also connect a spectrum analyzer to show the concurrent transmission of DOCSIS 3.1 and DOCSIS 3.0 channels.

DOCSIS 3.1 will help operators deliver the speed and performance to deliver tomorrow’s services, and ARRIS is at the forefront of this technology implementation.

And very soon, we’ll be unveiling several new advanced broadband DOCSIS 3.1 devices. Stay tuned!

ARRIS Announces the General Availability of AgileMax™ and Introduces HPON™ (Hybrid Passive Optical Network) Architecture

Today, we’re proud to announce the general availability of AgileMax, our revolutionary HPONAgileMax_Front(hybrid passive optical network) solution to completely eliminate Optical Beat Interference (OBI) in Advanced DOCSIS, FTTP deployments.

The AgileMax demo packed our booth at last year’s SCTE because of our promise to eliminate OBI—one of the long-standing challenges to deploying fiber to the home (FTTH) with RFoG technology. OBI is a chronic performance issue caused by multiple Optical Network Units (ONUs) communicating at the same time over the same fiber, resulting in unpredictable performance only worsened by network advances like DOCSIS 3.1. OBI has plagued RFoG deployments and prevented mass rollouts for over a decade, until now…

AgileMax— the backbone of ARRIS’s HPON solution – enables the industry’s only OBI free, DOCSIS based FTTP solution. The ARRIS AgileMax engine enables previously unachievable split ratios, reaches, and data rates, while remaining completely transparent to traditional PON solutions. AgileMax and HPON are CMTS, ONU, and cable modem agnostic—making this the most  flexible, cost-effective, operationally efficient and future-ready solution available. AgileMax promises to revolutionize fiber deployments around the world.

ARRIS Talks CCAP Migration @ Customer Leadership Forum

CCAP or Converged Cable Access Platform is paving the way for the industry’s migration towards a common video and data delivery platform.

CCAP is a hot topic at this week’s Customer Leadership Forum (CLF) for the Caribbean and Latin American(CALA) region. Mauricio Janisset, Staff Solutions Architect, mentioned in his talks this week that while CCAP defines a particular architecture, there are numerous ways to reach that converged endpoint.

The question remains: how will the industry implement CCAP?

The answer, of course, is multifaceted, but it’s important to understand that the CCAP initiative addresses a common and urgent need to enable more narrowcast QAM channels in a more dense and power-efficient footprint. Service providers with several CMTS and Edge QAM architectures rely on a range of technology suppliers and various service delivery goals—and their approaches to CCAP will vary accordingly. But while CCAP is a technology and an architecture, it is also an evolution…

Picking the right evolutionary path is critical not only for reaching the right destination, but also for ensuring that the journey matches your infrastructure, capabilities, and business requirements.

This has been the subject of many discussions in the context of CALA, this week, but for a more detailed look at CCAP considerations, check out this white paper from Tom Cloonan – our CTO, Network Solutions – and Todd Kessler – our VP Product Line Management.

E6000 Wins Driving Tomorrow’s Video and Broadband Services

Our E6000™ Converged Edge Router gives service providers around the world new levels of network capacity and efficiency—a competitive advantage in delivering today’s services and the scale for driving E6000_360__1tomorrow’s video and broadband experiences.

This week, we announced that Cable TV of East Alabama  and Comporium will deploy the E6000 to their respective subscriber bases. The E6000’s footprint covers a growing footprint of millions of live consumers.

The Motley Fool called the E6000 “a bigger success than anyone predicted.” We’ve seen demand from operators grow by leaps and bounds since we launched the platform last December. That’s due in large part to its capability to realize incremental revenue for providers of all sizes—enabling more operators to take advantage of new efficiencies, while offering a customizable pathway to future services.

On a larger stage, that’s what ARRIS’s end-to-end platform is doing for today’s providers. It combines our legacy of leadership in video and broadband with solutions that span the entire content delivery chain—from the headend to the home. Our E6000 is just one of the ways that we’re collaborating with our customers to invent the future.

Answers to Key DOCSIS 3.1 Migration Questions

Jeff Walker

Jeff Walker-Sr. Director, CMTS Product Marketing, ARRIS

With more headlines and data pointing to consumers’ increasing desire for TV Anywhere, multiscreen services, OTT and IP video, we know it’s crucial for service providers to look for ways to further optimize their network.

More providers than ever are transitioning to higher-speed, wideband DOCSIS 3.0 technology. In fact, DOCSIS 3.0 device shipments are expected to comprise nearly 90 percent of worldwide cable CPE shipments in 2014. And the good news is that by taking full advantage of DOCSIS 3.0, service providers not only optimize the performance of their networks, but also prepare those networks for a smooth migration to DOCSIS 3.1.

So where exactly are we in regards to the DOCSIS 3.1 migration? How do cable providers get there? And perhaps the question on most everyone’s mind…is it possible to ensure a smooth migration path? Thankfully, the short answer to the last question is “yes.”  But let’s address these questions in greater detail – as well as some additional key points related to DOCSIS 3.1.

First, what exactly will DOCSIS 3.1 do for cable providers? Under appropriate conditions, DOCSIS 3.1 will enable providers to achieve up to a 50 percent increase in data throughput in the same spectrum supporting speeds up to 10 Gbps in the downstream and 1+ Gbps in the upstream.

DOCSIS 3.1 enables expanded speeds through the use of OFDM, which uses multiple sub-carriers in channels up to 192 MHz in width, and Low Density Parity Check (LDPC) forward error correction, which is more efficient than the Reed-Solomon FEC codes used in early DOCSIS versions. The combination of OFDM and LDPC allows providers to use higher modulation orders – 1024, 2048 and 4096 QAM – and enable maximum throughput across various HFC plant conditions.

So where do we stand in the DOCSIS 3.1 migration timeline? DOCSIS 3.1 specifications were released in October 2013, and many vendors are currently developing compatible products. DOCSIS 3.1 enables providers to provide compelling service offerings in a dynamic, competitive marketplace. They can meet the growing demand for managed and OTT IP video services as well as data and traditional video services, such as VOD and nDVR.

The expectation is DOCSIS 3.1 testing will begin later this year and into 2015. Deployments will more than likely begin in late 2015 and early 2016. But it’s crucial for providers making significant investments in their deployed DOCSIS 3.0 CCAP technology to offer software upgrades to key aspects of DOCSIS 3.1. This will enable them to offer enhanced downstream speeds beyond what is possible with the bonding of multiple 6 or 8 MHz channels.

Maybe by now you’re wondering how one might approach this migration path? Thankfully, the migration to DOCSIS 3.1 can be a multi-phased approach making it easier to adapt to the change.

It’s good to know from the start that the migration can be done separately on the downstream and upstream channels. This allows for quicker expansion on the congested downstream channels using some of the DOCSIS 3.1 features. From there, upstream support can be implemented later when additional upstream bandwidth is necessary.

Additionally, providers can start using DOCSIS 3.1 on their existing spectrum in 96MHz or 192MHz blocks and then later adapt their plant and expand to use the higher downstream frequencies up to 1.2 GHz or 1.7 GHz defined in the standards. This approach can make use of “holes” in existing spectrum, and support the gradual insertion of the DOCSIS 3.1 modems into their systems.

One of the operating modes that can aid in the migration to DOCSIS 3.1 is enabled by turning off a block of OFDM sub-carriers in the OFDM channel and operating a single-carrier QAM channel within that spectrum.  DOCSIS 3.1 modems and DOCSIS 3.0 modems will be able to operate in the same serving group with the DOCSIS 3.1 modems using both the OFDM and SC-QAM channels and DOCSIS 3.0 modems operating in single-carrier QAM channels.

Finally, the DOCSIS 3.1 migration is made easier and more cost-effective if the same CCAP line cards being used for DOCSIS 3.0 services can be upgraded to support 3.1 via a software upgrade. This saves the provider from an expensive line card replacement. It is also important to have a CCAP with the necessary capacity in the switch fabric, mid-plane, power and cooling. Ultimately, the overall system should scale to beyond 1 Terabit/s of throughput with the appropriate QoS control, traffic managers and network-side interfaces.

In summary, the DOCSIS 3.1 migration aims to be fairly straightforward because of both backward compatibility with DOCSIS 3.0 modems and gateways AND the ability to preserve today’s CCAP investments. Testing of compatible cable modems and gateways will commence later this year followed by upgrades to deployed CCAP systems. All of these initiatives strengthen the cable providers’ position to optimize the performance of their systems to support the growing demand for IP video, data and traditional video services.

We’re not too far away, and I’m looking forward to sharing more updates as we continue down the path to DOCSIS 3.1.
