CLEC US Lec Corpa (MM)

Flexible, high-bandwidth Internet, data service provides easy integration with existing platforms CHARLOTTE, N.C., Aug. 28 /PRNewswire-FirstCall/ -- US LEC Corp. (NASDAQ:CLEC), a full-service provider of IP, data and voice solutions to businesses and enterprise organizations throughout the Eastern United States, today announced the availability of its Ethernet Local Loop transport service to the metro and surrounding areas of Louisville, Ky. "US LEC now offers Louisville one of the most flexible and efficient Internet and data transport services available," said Joe Brooks, regional vice president of sales for US LEC. "In addition to its compatibility with the near-universal Ethernet technology, Ethernet Local Loop also offers flexible bandwidth options, allowing customers to buy bandwidth incrementally - to as much as 500 megabytes." Ethernet Local Loop carries traffic based on Internet Protocol (IP), creating a platform or transport service for a broad range of US LEC services for businesses in Louisville. These IP services include US LEC's MPLS VPN data networking and high-bandwidth Internet access. With the addition of Louisville, US LEC now offers Ethernet Local Loop in 16 of its switching cities, including Atlanta; Baltimore; Charlotte, N.C.; Fort Myers, Fla.; Jacksonville, Fla.; Miami; Nashville; New York City; Orlando, Fla.; Philadelphia; Pittsburgh; Richmond, Va.; Tampa, Fla.; Washington, D.C.; and West Palm Beach, Fla. US LEC plans to fully deploy Ethernet Local Loop throughout its entire Eastern U.S. footprint by the end of 2006. Ethernet - A Familiar and Cost-Effective Technology Ethernet is one of the most deployed data networking technologies. On most computers, servers or routers -- almost any networked device -- you will find an Ethernet port for networking. It provides individuals, organizations and businesses the connectivity to a wide variety of applications, such as sending and receiving e-mail and connecting to the Internet or networks for printing, file sharing and collaboration. US LEC Ethernet Local Loop extends the use of this established and familiar technology to business' high bandwidth data transport and Internet access between multiple locations. Because Ethernet is so widely deployed, it is an easy and cost-effective way for customers to connect to a high-bandwidth data network. An example of its use is an enterprise with an inventory management system that needs connectivity to ensure all of its locations view real-time supply information or have access to its alternate supply chain via the Internet. Ethernet Local Loop can provide the transport to make applications like these possible. Accommodating On-Demand and Increment Growth Businesses with high-bandwidth needs are typically those most likely to need the flexibility to "burst" or quickly increase their bandwidth as their business requires it. With US LEC Ethernet Local Loop customers can easily add more bandwidth without the time delay and expense of ordering and installing new T-1s. For instance, Ethernet Local Loop can be purchased in 1MB increments starting from 3.0 Mbs to 500 Mbs, often without a change to their local loop. Businesses with variable Internet access needs can add a "burstable" option that guarantees a specific speed 24 x 7, but also allows "bursts" to a full 100 or 500 Mbs to handle heavy, intermittent Internet traffic. For instance, when a business runs a TV advertisement expected to attract significant traffic to their Web site, "bursting" accommodates this infrequent demand. This lets businesses manage infrequent, heavy traffic without having to purchase large amounts of bandwidth full-time. Backing up a company's computers onto a network data back-up solution, like US LEC's Data Back-up and Recovery, is another application that may result in burstable data. For multi-location customers utilizing MPLS VPN for data transport through its Ethernet Local Loop connection, US LEC offers speeds ranging from 1Mbs to 500Mbs. MPLS VPN also offers quality of service (QoS) guarantees. Quality guarantees ensure a business's most sensitive and demanding traffic, such as Customer Relationship Management applications or inventory management systems, receive priority delivery versus other non-priority traffic like Internet web surfing or e-mail applications. As priority activity decreases, bandwidth opens for other applications, allowing businesses to buy and utilize only the bandwidth they need and reduce costs.
