ADC Telecommunications Announces NewNet IP CALEAserver for Next Generation Networks.

MINNEAPOLIS--(BUSINESS WIRE)--Sept. 29, 1999--

NewNet IP CALEAserver(TM) Application Provides the Capability

to Meet CALEA Requirements in Next Generation Networks

ADC Telecommunications, Inc., (Nasdaq:ADCT; www.adc.com) announced today the NewNet IP CALEAserver for Internet Protocol (IP) CALEA compliance. ADC's NewNet IP CALEAserver works in conjunction with the Next Generation Networks' (NGN) voice over packet solution, specifically voice over IP (VoIP), to provide a number of telephony services. ADC also offers other CALEA-compliant lawful intercept solutions for the circuit switched network, including the NewNet CALEAserver(TM) and NewNet CDCmanager(TM).

CALEA stands for Communications Assistance for Law Enforcement Act. CALEA requires wireless and wireline telephone carriers to upgrade their networks to provide court-ordered intercepted call data and call identification information to one or more governmental Law Enforcement Agencies (LEAs) by June 30, 2000 for circuit mode communications and September 30, 2001 for packet mode communications.

Lawful access within a packet switched network requires the involvement of VoIP network elements, including a new element for the IP CALEA application. The NewNet IP CALEAserver is a new network element responsible for receiving the intercepted communications data from various packet switched network elements, such as the trunking gateways and call agents, and then redistributing the appropriate data to the collection facilities of law enforcement agencies. The first phase of this application will be available in January 2000.

"The IP CALEAserver is the first application which solves one of the most difficult telephony issues lawful intercept following the CALEA requirements," said Dr. Keith Bhatia, vice president of sales and marketing for ADC's NewNet Division. "The IP CALEAserver will provide law enforcement with data and IP voice as required by the CALEA law."

"As a leading SS7 middleware and enhanced services platforms provider, we are now taking our expertise in telephony applications into the next generation network," said Grant Wakelin, president of ADC's NewNet Division.

More information on ADC's NewNet IP CALEA solution will be provided at the ADC booth (#231/233) at the Fall '99 Voice On The Net trade show and conference, September 28-30 in Atlanta, Georgia.
