ADC to Integrate Pulsecom's ADSL Technology Into Its Broadband Access Platform.

Business Editors

HERNDON, Va.--(BUSINESS WIRE)--Feb. 8, 2000

Leading Provider of Digital Loop Carrier (DLC) Systems

Will Incorporate Key Technology to Deliver

Integrated ADSL Support to Remote Customers

Pulsecom today announced that it has established a strategic relationship with ADC, a leading global supplier of network equipment, software and integration services for multiservice, broadband networks.

The relationship will enable ADC to integrate ADSL technology from Pulsecom into ADC's broadband multiservice DLC to provide an ADSL-ready solution for remote subscribers.

With this integrated solution, service providers can extend ADSL to their remotely-located subscriber base with the same platform they use to provision telephone service to these users.

With its own WavePacer(TM) Remote Access Multiplexer (RAM) family, Pulsecom was the first to deliver a universal solution for extending ADSL and DSL-Lite services to remote subscribers who are served by DLCs. The company was also the first to deliver such a solution for the international market, using the E1 standard.

DLCs are used extensively in most PTT's territories to deliver communications services to subscribers in areas that cannot be served by a provider's Central Office (CO) directly. In addition, DLC deployment is growing substantially outside of North America -- particularly in developing countries.

These factors combined mean that a solution for extending ADSL to those customers served by DLCs is critical to the future of mass-market ADSL.

ADC is a leading provider of DLC systems, with its flagship product, BroadAccess(TM), a world-class multiservice access platform optimized for SDH/PDH fiber-based networks, supporting services from POTS to xDSL. The platform interfaces to virtually any type of local exchange through V5.2/V5.1/CAS digital protocols or 2W connection, and to ATM backbones through E1s or STM-1 UNI.

&uot;Our customers were demanding a complete, ADSL-ready access solution that would allow them to tap the growing subscriber base served by our systems,&uot; commented David Goldschmidt, vice president of marketing, Teledata Division of ADC's Broadband Access and Transport Group.

&uot;Pulsecom provided the ADSL technology that enabled us to complement the offering to our customers, including the provision of ADSL services to the BroadAccess (TM) installed base.&uot;

&uot;With Pulsecom's technology, we can now provide our customers with a standards-based solution that is interoperable with a wide variety of CPE,&uot; added Goldschmidt.

&uot;We are seeing significant interest in our ADSL technology from international markets,&uot; said Sassan Babaie, vice president of sales and marketing for Pulsecom. &uot;Being able to deliver a fully integrated access system that is ADSL-ready should give ADC a competitive edge in the international market and will help Pulsecom tap this market.&uot;
