SUWANEE, Ga. -- ARRIS (Nasdaq: ARRS) today announced an industry first, having successfully performed multiple Cable Modem Termination System (CMTS) hitless software upgrades with Comcast.

Accomplishing a “hitless upgrade” has been an important goal within the industry. This capability enables operators to more seamlessly perform the software upgrades needed to launch new high-speed and voice services. Results can include: increased network reliability, enhanced customer experience, and reduced operator costs.

Comcast and ARRIS leveraged the innovative ARRIS Cadant® C4™ CMTS hardware redundancy features and automated software upgrade process in their landmark hitless upgrades to the Cadant C4 CMTS Release 4.0 software.

“At Comcast, we are focused on continuously advancing our network, rolling out new built-for-broadband services, and ultimately creating the best broadband experience for our customers. This is what has led Comcast to become our nation’s number one broadband provider,” said Dave Fellows, Comcast chief technology officer.

“ARRIS’ industry milestone fully supports this vision, enabling Comcast to support all of our new service launches with regular software upgrades that we expect to be transparent to the customer. We value ARRIS’ understanding of the important need to balance technology advancement with the customer experience, and we are pleased to have worked with them on achieving this industry milestone,” continued Fellows.

“The Cadant C4 CMTS continues to redefine the definition of Carrier Grade,” said ARRIS VP, Engineering Dan Hickey. “We greatly appreciate the close working relationship with Comcast and are proud that we could achieve this industry milestone together."
