Competitive Business Telecom Provider Expands Service Area and High Bandwidth Telecom Services

DENVER -- Integra Telecom Inc., a facilities-based, integrated communications provider for business, has invested an additional $3 million in its Colorado telecom network. By upgrading its best-in-class telecommunications network, Integra has expanded its service area and added product offerings to include:

* VPN solutions: an Internet Protocol Virtual Private Network (IP-VPN) service providing a secure, multi-site, private network.

* Integra's Network Solutions: a secure private network transport service.

* Ethernet Solutions Metro E IP: increased Internet bandwidth for business via native Ethernet protocol.

"We're excited to have made such substantial investments in our Colorado network and to expand our service area and portfolio of voice and data solutions for businesses," said Ken Worcester, senior vice president of Integra Telecom of Colorado. "These services give Integra customers a competitive edge by eliminating excess costs, streamlining multiple telecommunications systems and providing robust connectivity."

Through its recent investments, Integra Telecom expanded its Colorado service area to include: Loveland, Pikeview, Aberdeen, and Montbello. With these additions, Integra's new services, as well as its full suite of business telecommunications solutions, are available to businesses in 30 communities throughout the Boulder, Colorado Springs, Denver and Fort Collins, Colo. areas.

"We see tremendous potential in Colorado as local businesses continue to demand the personalized service and diverse portfolio of customized voice and data solutions that Integra offers. Our recent investments will position Integra to best serve Colorado businesses; providing the reliable services and responsive customer care our customers have come to expect," continued Worcester.

VPN and Integra's Network Solutions

Integra's IP-VPN and Network Solutions are both delivered using Multi-Protocol Label Switching (MPLS) technology, which allows business customers to combine voice, data and Internet traffic onto a single cost-effective and easy-to-manage IP-based network that scales as their business grows.

Integra's MPLS technologies provide customers the security and reliability of private line telecommunications with the simplicity, speed and scalability of packet-based networks. Integra customers using MPLS technology maintain the option to control their network or have Integra configure and maintain equipment and routing instructions to best use the network while supporting, voice, data, video, and other mission-critical applications. The technology is customizable for business networks of all sizes, and locations can be easily added or removed.

Benefits of Integra Telecom's MPLS Technology:

* Connect and mesh multiple locations with an array of access types, upgrade bandwidth and change network configuration with minimal effort and cost.

* Converge multiple applications and traffic types onto a single network.

* Allow network managers to give voice and data applications priority, as needed, using Quality of Service (QoS) tagging or Class of Service (CoS) priority.

Integra Ethernet Solutions

Integra's new Ethernet Solutions provides a native Ethernet connection without the extensive costs of building a direct fiber connection. Integra's Ethernet Solutions offers options of five, 10, 15, 20 or 30 megabits per second (Mbps) of full-duplex, symmetrical IP bandwidth; ensuring equal upload and download speeds. These increments allow for growth, while making it possible for customers to choose a bandwidth that meets their current business needs.

In addition to Ethernet and MPLS services, Integra Telecom launched Broadband Internet services for Colorado businesses in August. Integra's Broadband Internet provides enterprise-level Internet access at rates that fit the small and medium-sized business budget.
