ADC NewNet's CALEAserver Enables Carriers to Comply with CALEA Wiretap Requirements.

MINNEAPOLIS--(BUSINESS WIRE)--June 4, 1998--

-- Software solution is first CALEA compliance product on the market and allows carriers to beat the rapidly approaching deadline --

ADC NewNet, a business unit of ADC Telecommunications, Inc. (NASDAQ: ADCT; www.adc.com), today announced its CALEAserver software, which allows wireless and wireline service providers to meet lawful intercept/wiretap requirements outlined in the Communications Assistance for Law Enforcement Act (CALEA). CALEAserver will be generally available for carriers to meet the original CALEA compliance date in late 1998.

Passed by the U.S. Congress in 1994, the CALEA law orders all telecommunications service providers to retool their networks to meet law enforcement agencies' wiretap capacity and capability requirements. The purpose of the act is to preserve wiretap ability as it is applied to new forms of telecommunications, such as wireless and digital. As part of CALEA, service providers who fail to complywith minimum upgrade requirements by the deadline (originally set for Oct. 28, 1998, but extensions currently being debated), are subject to $10,000-a-day fines.

CALEAserver is based on ADC NewNet's own state-of-the-art, open-architecture Signaling System 7 (SS7) stack. Deployed as an adjunct to network switches, the system is compatible with offerings from a variety of switching vendors, while also providing both wireless and wireline network capabilities. CALEAserver collects pertinent call information and allows carriers to provide secure access to that information by law enforcement agencies that obtain court-ordered wiretap directions.

The system's open, standards-based architecture accommodates all lawful intercept requirements today as well as those passed in the future. Subsequent items requested by the Federal Bureau of Investigation (FBI) can be added as a field software replacement. This includes the proposed FBI "punch list" items such as near real-time message handling and continuity check on voice channels. CALEAserver also is scalable, covering as many as four switches with a single unit.

"We are working actively with access function providers -- typically switch manufacturers -- and collection function providers to ensure interoperability in providing complete CALEA solutions," said Dr. Keith Bhatia, ADC NewNet's Executive Director of Business Development and Product Line Director for the Wireless Intelligent Network Group. "Our CALEAserver application is compliant with the present standard (Telecommunications Industry Association J-STD-025) and will also offer several additional features desired by law enforcement agencies."

"The CALEAserver is modular in design, ensuring fast time-to-market for both access and collection function connectivity," said Dr. Cemal Dikmen, Manager, Engineering for CALEAserver. "It is our intention to ensure that all new features include the 'punch list' items."

At Supercomm '98, being held June 9-11 in Atlanta, ADC (Booth No. 839) will demonstrate a working example of a CALEA-compliant call intercept. Using simulated access and collection functions, ADC's CALEAserver will show how a typical court-ordered intercept can be collected by a law enforcement agency. This simulation will demonstrate CALEAserver's capabilities, including:

-- Simultaneous delivery of voice (call content) and data (call detail records) -- Real-time display of call content messages -- Implementation of TIA standard J-STD-025 delivery interface messages
