Exhibit 99.3

October 11, 2011

To All ARRIS Employees:

We are pleased to inform you today that ARRIS and BigBand Networks announced that we have entered into a definitive agreement whereby ARRIS will acquire BigBand Networks by means of a tender offer.

With the addition of BigBand’s experienced employees, this acquisition further extends ARRIS’ capabilities in the processing, management and distribution of digital video content and represents an important acquisition of innovative technologies that will accelerate time-to-market and increase opportunities for ARRIS in several fast growing product areas. These include the Converged Cable Access Platform (CCAP) architecture defined by CableLabs^®, Local and Targeted Advertising, IP Video Distribution, and Advanced Video Processing and Compression. BigBand’s valuable patent portfolio, coupled with their expertise in digital video networking will enhance ARRIS’ technological leadership as the telecommunications industry moves to an all IP Converged Network Architecture. And BigBand’s success in penetrating the telco markets with their advertising and video networking technologies will give ARRIS additional Customer and Segment Diversification.

Please join me in welcoming the BigBand Networks employees around the world who will be joining our organization once the transaction is complete. BigBand has a significant presence in Tel Aviv, Israel; Shenzhen, China; Redwood City, CA; and Westborough, MA. These sites will complement ARRIS existing facilities around the world.

Over the next several weeks, while we await regulatory and shareholder acceptance, we will begin planning the transition to one organization, making sure to understand the strengths of each organization and to build upon them. Although many decisions have yet to be determined, we will continue to communicate with employees as the process proceeds, in anticipation of a closing date in late 2011.

In the meantime, it is business as usual as we have customers to serve and products to build. Please stay focused and continue executing on our current business plans in order to realize the success we know we are capable of achieving. I would like to thank you for your solid efforts to date that have positioned us to make this next exciting step that we are announcing today possible and look forward to your continued support as we work together to achieve our desired results for our customers, shareholders and very importantly each of you.
