MINNEAPOLIS--(BUSINESS WIRE)--April 5, 2000

Performance Software to Monitor Taiwan's Largest Wireless Network

ADC (Nasdaq:ADCT; www.adc.com) today announced another win in Asia Pacific for its leading network performance reporting solution, Metrica/NPR. Chunghwa Telecom Co., Ltd. (CHT), Taiwan's PTT, has selected several solutions from the Metrica product family via prime contractor Teltai (Taiwan) Ltd.

Metrica/NPR for Wireless will be used to monitor CHT's wireless (GSM/DCS and AMPS) networks, interfacing with Nortel and Ericsson infrastructure elements. CHT, which was founded in 1996 when it inherited the role from the Directorate General of Telecommunications, Ministry of Communications, will be seeking to gain competitive advantage in a rapidly developing market. It is currently the largest mobile telephony operator in Taiwan with more than 3.5 million subscribers. Covering the whole of Taiwan, CHT will use the Metrica/NPR solution to enhance its network performance and service quality.

Metrica/NPR, used by 160 mobile and fixed networks around the world, stores large volumes of performance measurement data and provides daily, weekly and monthly reports on a wide range of operating parameters, such as traffic and grade of service. Operators use this information to forecast network growth, diagnose faults, and optimise performance. In addition to Metrica/NPR, CHT will use Metrica/PAS (performance alarm server) to monitor both performance data and historical data stored by Metrica/NPR against thresholds and alert operators to potential abnormalities. As part of the implementation, CHT will be able to view network performance information in its geographical context and display performance highlights, trends and faults on maps.

"Keeping good network quality is the best policy to serve our customers. Metrica/NPR performance management system can provide fast and accurate performance response of mobile networks and increase efficiency of our optimization work," said Mr Mu-Piao Shih, managing director of Mobile Communications Department for Chunghwa Telecom, Long Distance & Mobile Business Group.

"The Metrica products will further enhance the ability of CHT to take on the competition in Taiwan, and we are happy to have this chance to work with the Metrica team to achieve this," said Albert Loh, president of Teltai.

"We are looking forward to helping CHT to face the challenges of maintaining and improving QoS in a market experiencing aggressive competition," said Richard Hsueh, vice president/managing director, Asia Pacific for ADC's Software Systems Division. "We are also delighted to have this opportunity to work with a prime contractor such as Teltai. Asia Pacific is a key region for Metrica products which have always been quickly adopted by leading operators in this part of the world."

ADC Metrica technology is deployed in 160 networks in 55 countries around the world. More information about ADC's Metrica products can be reached on the Web at www.metrica.com, where complete details about its expertise and range of products are available.
