ADSE Seamlessly Integrates Voice and Internet

Solutions with Scalable, Flexible Architecture

ADC, (Nasdaq:ADCT; www.adc.com) a leading global supplier of fiber optics, network equipment, software and integration services for broadband, multiservice networks, today announced the release of its Advanced Data System Environment (ADSE) 2.0, the core operating environment for ADC's Broadband Services Platform. ADSE 2.0 dramatically expands the core platform upon which ADC's multiple services operate. Now ADC's products, such as the Unified Message Portal (UMP), Internet Call Manager (ICM) and Voice Profile over Internet Mail (VPIM) will benefit from ADSE 2.0's advanced new features designed to bring adaptive communications to reality.

With its release of ADSE 2.0, ADC brings to market a communication systems environment that adapts to changing network technologies and provides seamless interoperability of enhanced services between a variety of devices and access methods. The open standards-based software environment provides the seamless integration of various voice and Internet applications in a scalable, flexible architecture that satisfies the reliability requirements of global service providers. ADSE 2.0 extends ADC's market expertise in adaptive communications by unifying the innovations collected through more than 2500 deployments and 225 customers across six continents.

"ADSE represents a transformation of our core adaptive communications systems, setting the stage for dramatic new growth," said Dana Love, vice president and general manager for ADC's Enhanced Services Division. "The key to any successful platform is interoperability that facilitates fast deployment, lower cost of ownership and flexible growth. ADSE will put this power in the hands of service providers worldwide."

ADC offers multiple adaptive communications services that will benefit from ADSE's enhanced interoperability, including:

-- Unified Message Portal (UMP), an application that enables subscribers to
access voice, fax and email messages over the Web using any e-mail client or
from a telephone interface.

-- Internet Call Manager (ICM) with Voice over IP (VoIP) functionality, that
permits subscribers to monitor and control their telephone calls while actively
connected to the Internet.

-- Voice Profile over Internet Mail (VPIM), that lets service providers connect
voice mail systems from different vendors through a common interface, saving on
infrastructure costs while increasing subscribers' access to messages.

Service providers using ADC's new ADSE technology can now build revenue generating services to help meet their subscribers' needs more rapidly than ever before. ADSE 2.0 is Internet-ready and supports multiple enhanced services from the same environment. This interoperability between adaptive communications systems translates to faster deployment and easier upgrades. ADSE 2.0 delivers these advantages with multiple pre-packaged adaptive communications services designed to reduce a service provider's total cost of ownership. The pre-packaged services also helps protect a service provider's infrastructure investment with improved compatibility with prior software releases. The result is a set of services that can adapt to subscribers' changing communications needs, access methods and mobility patterns, all from the same core system.
