Integra Telecom Selects Hatteras Networks for Mid-Band Ethernet Rollout

Hatteras Networks, the global leader in flexible Ethernet solutions for enterprise access services and next-generation cell tower backhaul, announced that Integra Telecom Inc., a facilities-based, integrated communications carrier for business, has selected the EtherFLEX(TM) HN4000 and HN400 family of Mid-Band Ethernet solutions to support its Ethernet-over-copper deployment. Hatteras Networks EtherFLEX solutions will enable Integra to rollout a highly resilient Metro Ethernet service offering at speeds of 5 to 30 Mbps to its business customers with initial deployments in Salt Lake City, Utah, and Boise, Idaho.

Hatteras Networks' EtherFLEX solutions feature the broadest, most flexible platform, with a scalable, pay-as-you-grow approach that will enable Integra to upsell bandwidth and managed Ethernet services as the service offering ramps up. Integra is taking advantage of the HN4000's dual GigE uplink options to ensure the error-free delivery of bandwidth delivered from the customer back to the network core. The redundancy delivered by Hatteras' unique cross-box bonding allowed Integra to build a highly reliable, resilient network platform. With Hatteras Networks' EtherFLEX platform, Integra Telecom will be able to dramatically extend the reach of its current Metro Ethernet service offering to customers that don't have access to fiber networks. Hatteras Networks solutions will support Integra's Ethernet Solutions product offering, enabling them to broaden the service area for existing Internet access services, penetrating much deeper into their current markets. Without the need for new infrastructure, Integra will be able to quickly capitalize on a largely untapped market opportunity while building a bigger, more capable network.

"We chose Hatteras Networks because of the unmatched resiliency, advanced feature set and maximum port density of its Mid-Band Ethernet solutions," explained Dudley Slater, CEO for Integra Telecom. "With Ethernet Solutions, supported by Hatteras' EtherFLEX product line, we'll quickly and cost-effectively enable existing and new customers to take advantage of high-bandwidth, highly reliable Internet access."

"Integra Telecom has found the fastest, easiest and most efficient means to extend the availability and capabilities of its Ethernet services with an offering that will satisfy the needs of business customers throughout its target markets," said Kevin Sheehan, CEO for Hatteras Networks. "With our highly reliable, resilient EtherFLEX solutions, Integra Telecom will be able to continue its deep-rooted tradition of delivering the highest quality customer service."

Hatteras Networks is demonstrating its new EtherFLEX service architecture at NXTcomm in booth SU3711 at the Las Vegas Convention Center from

June 17 to June 19, 2008.

About Hatteras Networks

Hatteras Networks is redefining the way carriers think about Ethernet services. Hatteras Networks' Ethernet service edge solutions are leading Service Providers worldwide to a $21 billion expansion of the Metro Ethernet market, which had previously been limited to the fiber footprint. Historically, T1s and E1s have been the fundamental building block for voice and data business services. Now, Service Providers can cost-effectively offer up to 45 Mbps Mid-Band Ethernet services over existing copper facilities, enabling businesses to migrate from legacy Frame Relay, ATM and T1/E1 connections to transparent Ethernet services for voice and data business connectivity, infrastructure backhaul and mobile wireless backhaul solutions.

Already deployed on five continents, Hatteras Networks solutions are enabling a market expansion for carriers that is as significant for business services as "triple play" is for residential. For more information, visit www.hatterasnetworks.com.
