HUNTSVILLE, Ala.--(BUSINESS WIRE)--March 22, 2004

ADTRAN(R), Inc. (NASDAQ: ADTN), the market leader in carrier and business class network access solutions in the U.S., today announced the opening of its new European Regional Headquarters in Dublin, Ireland. This office will increase ADTRAN's access to the world's second largest networking market and make ADTRAN sales personnel and product information more readily accessible to the region's enterprise business and service provider customers.

Heading the new European Regional Headquarters is Ed Werner. Werner is responsible for establishing distributor and reseller channels in the EMEA market, thereby extending the market reach of ADTRAN products. Werner has over 20 years of experience in the telecommunications industry in the EMEA region. Prior to joining ADTRAN, Werner served in a number of senior positions within Lucent Technologies and AT&T, focusing on channel development and sales. Werner was responsible for creating Lucent's Global Business and SYSTIMAX(R) channel partner programs, one of the world's largest reseller networks.

"The European, Middle Eastern, and African markets offer a wealth of opportunity for growth in our global business base," said Ed Werner. "ADTRAN's NetVanta(R) products comply with global standards and offer distinct price advantages while providing the features customers need for today's high-performance networks. Now customers in the EMEA market have a choice in their supplier of networking equipment -- one that provides greater value and quicker return on investment."

The opening of the EMEA regional headquarters coincides with ADTRAN's announcement of an EMEA-wide distribution agreement with Anixter International, the largest global distributor and logistics services provider of wire, cable and connectivity products and services. Under the terms of the agreement, Anixter will distribute ADTRAN's line of enterprise networking solutions, with special emphasis on the NetVanta family of access routers, Ethernet switches, and VPN/firewall offerings. This will increase Anixter's presence in the networking market, while providing ADTRAN with the global logistical support and reseller base necessary to expand in the region.

"ADTRAN has built a reputation in the United States for providing top-quality products at market-leading price points," said Werner. "That foundation has made ADTRAN one of the world's most successful network access companies, with a 16-year history of profitability. Our mission is to take the same attributes that have made ADTRAN successful in the U.S. and build an equally impressive legacy in the EMEA market."
