Support for the ARRIS SURFboard® SB6141 and SB6121

We’d like to clarify some confusion around our popular SURFboard® 1-big-SB6141_Right_SideSB6141 and SB6121 cable modems.

The SB6141 

There are currently no plans to end production of the SB6141 and you can still buy the product at your favorite stores: AmazonBest BuyNewEgg, and the ARRIS SURFshop.

After all, it’s one of the most reliable modems on the market and one of the best investments you can make as a cable customer.

The SB6121

The SB6121 is being phased out and replaced by the SB6141.  However there are many SB6121s still available for purchase, and we’ll continue to provide technical support for this device.

We’ve also seen some confusion around both of these products’ use with Comcast’s XFINITY Internet service.  Here’s what you need to know:

  • If you purchased (or plan to purchase) your SB6141, Comcast will continue to provision and support it.  You’re protected by our industry-leading two-year warranty.  So sit back, relax, and enjoy the fast Internet the SB6141 provides.
  • If you previously purchased an SB6121, Comcast currently will continue to provision and support it.  However, Comcast advises customers that this device is not recommended for any speeds above its 105 Mbps tier.
  • Comcast has updated its compatibility site at to clarify that the purchased versions of the SB6141 and SB6121 are approved for use.
  • If you LEASE your SB6141 or SB6121 from Comcast, those devices will continue to work, but Comcast will not be LEASING any new SB6121 or SB6141 units, and will be transitioning you into a newer device in the not-too-distant future.

If you have questions about our SURFboard SB6141 or SB6121, please contact us here.  Also, visit us at to view our entire portfolio and find a product that fits your needs.

Making DOCSIS® 3.1 a Reality this Year

DOCSIS® 3.1 has long been touted as the technology that will bring Gigabit services to the e6000_heromasses, so that consumers can enjoy faster broadband connections. It’s a technology that a number of service providers are looking to deploy in 2016, and one that ARRIS helped pioneer.

Today, it is exciting to see that DOCSIS 3.1 is becoming a reality. Comcast just announced that it will bring the world’s first DOCSIS 3.1 Gigabit Internet service to residential and business customers beginning in five US markets in 2016, using existing connections. We are excited to be part of this effort by supporting rollout in four of these markets with our flagship E6000® Converged Edge Router (CER) and a software-only upgrade.

When it comes to DOCSIS, we have a strong track record of pioneering innovation – from our work in developing the standard itself, to our unmatched technical expertise and the DOCSIS-based network deployments we have successfully completed around the world. This puts us in a unique position to bring this technology to market at scale. We recently unveiled new DOCSIS 3.1 modems for operators and retailers that complement our robust DOCSIS 3.1 network portfolio. And our E6000 CER is software-upgradable to DOCSIS 3.1 to help deliver on the full promise of multi-gigabit services to the home.

As more connected devices, streaming video and advanced services make their way into the home, consumers expect nothing less than fast speeds and reliable connections. We expect Gigabit speeds to the home to be the new standard by which broadband service providers will be measured. We are ready to continue working with our customers in 2016 to enable the smooth migration to these next-generation technologies – and provide the best-quality entertainment and communication experience in the home.

He will be truly missed,” states Bob Stanzione, ARRIS CEO.

Celebrating Engineers Week: Jack Birnbaum, Comcast

2014-04-26 16.30.10

Jack Birnbaum, VP of Video Control and Security

As we continue to celebrate National Engineers Week, we interviewed Jack Birnbaum, VP of Video Control and Security at Comcast about his inspiration to become an engineer.  Read below for the full interview.

What inspired you to become an engineer?

  • I like to solve problems and create things.  I was always interested in figuring out how things worked.  I had always been strong in math and science and was looking for a practical way to apply those skills.  Initially, I became interested in bio-medical engineering.   I was enamored with the idea that I could create solutions that would help people improve their health.  When I was in college, this field was mostly research-oriented, so I moved to computer engineering.

What does a day in the life of an engineer at Comcast look like?

  • The day in the life of the Comcast engineer has changed much in most recent times.  These days, we work in an agile development environment.  The engineers typically start their day with a 15-minute scrum, discussing activities completed, challenges encountered and commitments for the next day.  They collaborate to assist one another to achieve the team goals.  The engineers then move off to their development work.  Many times the engineers work in team areas so there is free flow of communication and collaboration.
  • On any day, an engineer may be called upon to perform demos of their work to product and business folks.  They may also be engaged in planning and evaluation of new projects.
  • Finally, since our teams are development- and operations-oriented, our engineers are often involved in monitoring the performance of our services with the goal of improving the customer experience.  If problems occur, they are counted on to work closely with our technical field personnel to analyze and resolve system issues.
  • At Comcast, we try to create an exciting environment for our engineers.  We have challenging projects that solve complex problems at a large scale.  We have innovation programs that challenge engineers to develop new concepts, some leading to Patent awards, some leading to new products and services.  We also consciously allocate time to encourage folks to develop new ideas or learn new skills.

 How do you collaborate with ARRIS engineers to solve industry challenges? 

  • Comcast has a long-standing partnership with ARRIS in developing solutions in the video space.  We work closely together to develop new products and solutions in the ever-changing video space.  As new technologies emerge, we look to our strong partners to help us determine solutions that meet the needs, are economically feasible and can deliver service with high quality.  With ARRIS, we have a partner with expertise in technology, integration and services.  Each of these areas is key to Comcast in delivering solutions that delight our customers.

 What are the most common challenges that engineers in our industry face?

  • I think the most common challenge that we face is change.  The industry is changing with new and different competitors.  The technology is changing with innovations in processing, storage, and networking.  Our customers’ expectations are changing as well.  There is a desire for more capabilities in more places.  What used to be video delivered to the TV is now video delivered to many devices, some in the home and some out of home.  There is a need to always be connected, which creates challenges to make sure that those connections are functional and secure.  There is a need to make sure all of the video content is displayed with high quality on many new devices.

What is one piece of advice you wish someone told you when you were pursuing a career in engineering?

  • The most successful engineers are flexible.  In this field, an engineer must be able to work with ambiguity.  Problems are not provided with all of the information needed and a path to a solution.  The engineer needs to be able to work with little information, discover the real problems to solve and create solutions.  When one adds the needs of the business, the engineer must be willing to change directions very quickly and continue to push toward the best solutions for our customers and our shareholders.
