ADC Doubles HDSL2 Reach with HDSL2 Repeater.

Business Editors &Technology Writers

MINNEAPOLIS--(BUSINESS WIRE)--Jan. 24, 2000

ADC (Nasdaq:ADCT; www.adc.com) today extended its leadership in the HDLS2 market with the announced availability of a new HDSL2 repeater. The repeater will allow deployment of T1 service up to 24,000 feet from a central serving office with one repeater in place, over a single copper wire, based on carrier serving area (CSA) guidelines. ADC's HDSL2 repeater is the first that operates over the full CSA loop lengths and provides line power to a remote unit. This expanded service area will enable carriers to reach the majority of their customers at full line rates using HDSL2 technology.

ADC's unique HDSL2 repeater design employs highly integrated silicon, which significantly reduces power dissipation while doubling the copper reach. When configured with ADC's Soneplex HDSL2 central office and remote modules, the system provides carriers an extremely cost-effective solution for service delivery. ADC's HDSL2 system offers a spectrally friendly solution, which does not interfere with ADSL, HDSL or T1 in the same binder group. Additionally, low-power dissipation permits greater deployment densities in an outside plant environment.

&uot;Through our use of best-of-breed technologies, ADC has developed a product that utilizes second-generation silicon to enable providers to expand their service delivery reach to more points in the network.,&uot; said Michele Bishop, Soneplex program manager for ADC's Broadband Access and Transport Group. &uot;ADC now gives customers a choice - a repeater solution for carriers wishing to double their reach and a standards-compliant system for HDSL2 service to 12,000 feet.&uot;

The ANSI committee developing the HDSL2 standard has to date developed placeholders within the standard in anticipation of repeater technology advances. ADC's HDSL2 repeater adheres to the repeater standardization work that has been completed, including the areas addressing interoperability. As demonstrated by HDSL2's 4-wire predecessor HDSL, ubiquitous loop deployments are only achievable when repeater modules are available. ADC has achieved this milestone with the availability of its HDSL2 repeater.

HDSL2 is the first standardized digital service that requires no compromise. The technology enables service providers to deliver full T1 performance over a single twisted pair cable with the same reach, robustness and spectral compatibility of today's two-pair HDSL. HDSL2 is ANSI-standardized and has been meticulously tested for spectral compatibility with other standardized services. It requires only one copper pair with no line conditioning and supports line power over the standard CSA radius.
