DES MOINES, IA--(Marketwire - Nov 5, 2012) - [ Calix, Inc. ] (NYSE: [ CALX ]) today announced it has reached the 100 Iowa customer milestone with the selection of the Calix Unified Access portfolio by Danville Mutual Telephone Company. For more than a decade, Calix has been serving the needs of communications service providers throughout the state and enabling the delivery of advanced broadband services to its residents and businesses. Beginning with one of the first deployments of the Calix C7 Multiservice Access Platform in 2001 and continuing with the deployment of thousands of platforms spanning the entire Calix Unified Access portfolio, Calix has remained committed to its strong Independent Operating Company (IOC) customer base in Iowa, as well as its over 1100 customers globally.

"Liberty Communications selected the Calix C7 back in 2001, as we began to roll out fiber in our network. With that selection, we became the second Calix customer in the company's history and it's first in Iowa," said Jerry Melick, President and General Manager of Liberty Communications in West Liberty, Iowa. "As our network has transformed into a primarily fiber-to-the-premises (FTTP) architecture, we have also added Calix E-Series solutions to our product mix. Throughout this 11-year partnership with Calix, their team has always had a vision for both their success as a company, as well as for our success as a service provider, looking beyond their hardware to support our business and help us reach our goals."

Calix has been a critical partner for its Iowa-based customers over the past decade as they have transformed their networks from primarily ATM and copper-based networks built to deliver voice and basic data services to the vast majority now delivering a rapidly expanding array of advanced IP and Ethernet broadband services such as IPTV over fiber and VDSL2. Throughout this transformation, the Calix Unified Access portfolio has evolved to support a wide array of new technologies and services while still providing personal service and support through the company's intimate customer engagement model.

"Since Calix was founded, we have taken great pride in our personal approach to customers, truly partnering with them as they evolve their copper- and fiber-based networks," said John Colvin, Calix Senior Vice President of North America Sales and Marketing. "As their networks and businesses have transformed over time, Calix has transformed with them, extending our Unified Access portfolio to meet their changing network requirements. In Iowa, with the vast majority of our customers delivering broadband services over fiber, we look forward to continuing to support their vision as they roll out the next generation of advanced applications."
