MINNEAPOLIS--(BUSINESS WIRE)--May 11, 2004

Equipment Ensures Reliable Delivery of High-Value

Services from the Data Center to the Desktop

ADC (Nasdaq:ADCT; www.adc.com) today announced it will showcase its portfolio of IP infrastructure solutions at the 2004 Networld+Interop conference May 11 - 14. The IP infrastructure portfolio supports the company's strategic initiative to become the leader in global network infrastructure solutions and services. ADC's new Global Network Infrastructure strategy includes the products, systems and services that provide the foundation for every type of communications network over every medium: fiber, copper, and wireless. These network infrastructure solutions will be featured in the ADC exhibit booth No. 2709 at Networld+Interop in Las Vegas, Nev.

"Establishing a solid network foundation rooted in connectivity has already proven successful as networks transition from analog to digital, circuit to packet, and from copper to fiber," said Robert E. Switz, president and CEO for ADC. "As organizations approach the convergence of voice, data and video with IP-based services, a foundation of connectivity remains just as essential. ADC understands the unique nature of high-performance networks - we listen to our customers' needs, we tailor solutions, and we build a network foundation that enables our customers to meet their business objectives."

As the first major step in ADC's Global Network Infrastructure strategy, the company recently announced an agreement to acquire the KRONE Group, a leading global supplier of copper- and fiber-based connectivity solutions and cabling products used in public access and enterprise networks worldwide. KRONE and ADC provide unmatched solutions for VoIP and Gigabit Ethernet networks. With approximately 70% of ADC sales in North America and approximately 80% of KRONE sales outside of North America, the combination of the two companies creates global scale with local presence that benefits customers with a broader technology expertise and competitive cost-leadership.

Large volume data users who depend on their unique, high-performance networks as a vital means of revenue creation require a network infrastructure capable of delivering next generation IP-based services. These include enterprises that view data as a product and critical to business operations, as well as carriers and service providers that operate large-scale data centers for their business customers. ADC's leading network infrastructure solutions are the foundation for high-speed, highly reliable networks throughout the world, and have already been deployed in sophisticated environments such as data-intensive financial services and banking networks; carrier-class data centers operated by service providers and enterprise organizations; highly-secure, bandwidth intensive government networks; real-time news and broadcasting networks; and mission-critical industrial security, process control and communications networks.

In addition to its physical layer connectivity solutions, ADC also provides systems integration services to help build network infrastructures. These services include planning, design, installation, deployment and optimization services. ADC installs network equipment from more than 60 of the world's leading active equipment vendors and has more than 20 years of integration experience on multi-technology and multi-service platforms.

At Networld+Interop, ADC will showcase its portfolio of IP Infrastructure solutions that address the unique needs of organizations deploying high-performance IP-based networks, including:

Power-over-Ethernet Infrastructure Solutions -- The new ADC Midspan Power-over-Ethernet Controller eliminates the need for installation of local power to devices such as VoIP phones and Wi-Fi access points, saving time and money. With the ADC Midspan PoE Controller, power for the network device is generated in a large corporation's telecommunications room, which is usually backed up by an uninterrupted power supply, and delivered over standard Category 5, 5e or 6 Ethernet LAN cabling, increasing reliability even further.

Media Conversion and Optical Extension Solutions -- The carrier-class, intelligent, and scalable ADC OptEnet media converter platform manages any network's Ethernet or SONET media transitions. Integrated intelligence allows the user to remotely monitor system performance and transmit alarm conditions to upstream operational support systems. Incorporating a patent-pending system architecture and leveraging ADC's leadership in connectivity solutions, the OptEnet platform provides the ideal solution for Ethernet extensions in support of transparent LAN services or switch router interconnect requirements. A variety of solutions are supported ranging from 10Mb to OC-12 to Gigabit Ethernet.

Ethernet Infrastructure Solutions -- The ADC Ethernet Distribution Frame (EDF) provides a cross-connect field that ties together all Ethernet network elements from multiple floors of the central office or point-of-presence, providing a common craft interface for performing adds, upgrades, and rearrangements on Ethernet services. The EDF typically consists of NEBS Level 3 Certified equipment such as ADC's patented Glide Cable Management, Category 5e and 6 Ethernet patch panels, and Fiber Management Trays. With the EDF installed, technicians can isolate elements, connect new elements, route around problems, and perform maintenance functions. The frame design supports network growth and flexibility in the Ethernet distribution system.

Optical Infrastructure Solutions -- ADC's optical infrastructure products and systems provide access, termination, and connectivity for fiber-based networks, including its family of high-density Next-Generation Frame products, FL1000 and FL2000 fiber patch panels, and the FiberGuide raceway system.
