Horry Telephone Cooperative Selects Calix as Fiber Access Supplier

PETALUMA, CA—March 1, 2010—Calix today announced that Horry Telephone Cooperative (HTC) (Conway, S.C.) has chosen the Calix Unified Access Infrastructure to deliver a variety of fiber services and applications in its network. The largest cooperative and the 18th largest Incumbent Local Exchange Carrier (ILEC) in the country, HTC is expanding its investment in advanced fiber access technologies to support a range of high-bandwidth services, including voice and advanced RF video to single family residences and multi-dwelling units.

HTC is utilizing gigabit passive optical network (GPON) technology in its network and plans to widely deploy the Ethernet eXtensible Architecture (EXA) Powered Calix C7 Multiservice Access Platform (MSAP) for residential and business GPON services and a variety of Calix 700GX Optical Network Terminals (ONTs) with the ability to support both GPON and Active Ethernet (AE) at the customer premises. The Calix Management System (CMS) will provide provisioning and service management across the entire Calix Unified Access Infrastructure.

"In our highly-competitive environment, it is crucial for HTC to deliver the most advanced services efficiently and effectively," said Frank Sarvis, chief executive network engineering of HTC. "Fiber to the premises provides us with the optimal delivery vehicle for addressing our competition head-on. The breadth and flexibility of the Calix fiber solutions portfolio gives us the tools we need to deliver the services that our customers want with the efficiency that our business demands."

Serving parts of Myrtle Beach and greater Horry County, South Carolina – one of the fastest growing areas in the country – HTC sees wide fiber deployment as key to its future. As HTC expands its fiber network and services, the Calix Unified Access Infrastructure provides the following benefits to HTC:

• The EXA Powered Calix C7 brings high density and services flexibility to HTC's targeted business and residential customers.
• The Calix family of 700GX ONTs deliver a variety of form factor and service options at the customer premises, including important residential features like integrated radio frequency over glass (RFOG) support, as well as key business service features like multiple T1 support. Calix ONTs provide HTC with optimized options for a range of applications.
• CMS provides HTC with a unified service activation and management model independent of service type, technology, or form factor.

"Service providers around the Southeast and cooperatives around the country look to HTC for its leadership in delivering advanced services to its customers," said John Colvin, vice president of field operations at Calix. "We feel privileged that HTC has selected Calix for its strategic fiber access initiatives. HTC is constantly raising the services bar throughout its service area, and Calix Unified Access solutions and innovation will continue will provide an ever-expanding set of options to allow HTC to continue to lead their market."
