Exhibit 99.3

September 23, 2007

To All ARRIS and C-COR Employees:

Today we are extremely pleased to announce that our respective companies, ARRIS and C-COR, have signed a definitive agreement to merge. The combination of our two businesses will create the leading pure play solutions provider to the global cable industry offering a full suite of IP telephony, high speed data, video infrastructure and video management solutions.

The combination of ARRIS’ leading voice, data and video products together with
C-COR’s leading access, transmission, video and software solutions will result in a much better positioned combined business than either company would have individually. We believe the combined business will be uniquely positioned to capture “triple and quad play” spending by delivering proven, next generation voice, data and video, transmission and software solution products to broadband service providers.

The combined organization will also have an impressive global footprint with excellent customer and product line diversity and an even stronger international sales, R&D, and support presence. This transaction will create a company that reported over $1.2bn in combined sales over the last four quarters. With over 2000 employees, the combined sales force, engineering and R&D, administration, marketing and manufacturing teams will be a formidable adversary to our competitors.

Over the next several months, while we await regulatory and shareholder approval, 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 early 2008.

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. We both 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.
