Helps Service Providers Deliver TDM HiCap DS1 Services Over

Existing Local Loop Copper and Fiber Facilities

ADC (Nasdaq:ADCT; www.adc.com) introduced today its new LoopStar(TM) 400 carrier-class broadband access and transport system that allows service providers to cost-effectively deploy HiCap DS1 services using their existing TDM networks and local loop copper and fiber facilities. The LoopStar 400 system's flexible architecture supports multiple network and loop interface options that help reduce capital costs and ease the transition into new business services. The LoopStar 400 will be featured in ADC's booth (No. 11219) at SUPERCOMM 2003, June 3-5 in Atlanta.

For Central Office TDM applications, the compact LoopStar 400 supports T1, HDSL, HDSL2, HDSL4 and optical DS2 line cards for DS1 loop services as well as DS1, DS3, STS-1 and OC-3 TDM network interface options. Additional features include integrated testing, monitoring and management control for each DS1. Environmentally hardened for installation in remote cabinets, the LoopStar 400 offers remote management for unmanned sites via in-band Data Communications Channel (DCC) communications over OC-3. Lab trials for the LoopStar 400 are slated to begin in June at a major ILEC.

The LoopStar product line leverages ADC's extensive experience in standards compliant HDSL2 and HDSL4 products that enable customers to deploy HiCap DS1 services over existing copper infrastructure with assured quality, high availability and spectral compatibility. This strict adherence to standards significantly reduces operational and equipment costs normally associated with proprietary implementations of HDSLx technologies. The LoopStar 400 has a forward-looking architecture that anticipates the day when most business data services will be operating at Ethernet speeds.

"The LoopStar 400 system is ideal for service providers who want to deliver HiCap T1 services while minimizing their overall capital and operational expenditures," said Mike Pratt, president of ADC's Wireline Systems Business Unit. "LoopStar builds on ADC's years of experience in offering business class service delivery that meets the needs of customers who want to offer new revenue-generating services by leveraging their existing network assets."

The LoopStar 400 platform is the latest addition to ADC's comprehensive portfolio of Wireline products for service providers and private networks. The portfolio also includes Soneplex Loop Extender Systems and Broadband Systems, HiGain modules, and Wideband System 3190 as well as PG-FlexPlus micro-DLC and ADSL edge solutions. ADC also offers a complete line of indoor and outdoor enclosures and enterprise and network management solutions.
