Netensity's AdvanEdge(TM) 1212 Platform Incorporates Legerity's

Intelligent Access(TM) Chipsets to Enable Integrated ADSL and

POTS Services in Multi-Subscriber Environments

Legerity, Inc., a leading communication integrated circuit (IC) provider for data and voice networks, today announced that its Intelligent Access(TM) chipsets provide a voice over broadband solution for the AdvanEdge(TM) 1212 Integrated Access Platform (IAP) from Netensity, Inc., an innovator in multi-service broadband access solutions for the multi-subscriber market.

Netensity's AdvanEdge 1212 IAP is a 12-port, standards-based communications platform that provides Digital Subscriber Line (DSL) access for integrated voice, data, and video applications in multi-dwelling unit (MDU) and multi-tenant unit (MTU) environments. Legerity chipsets designed into the AdvanEdge platform include a four-channel Intelligent Subscriber Line Audio-processing Circuit (ISLAC(TM)) codec/filter and an Intelligent Subscriber Line Interface Circuit (ISLIC(TM)) device with integrated ringing. These circuits -- the Am79Q2242JC Quad ISLAC codec/filter and the Am79R241 ISLIC -- are members of Legerity's Intelligent Access Voice Solutions, a chipset family optimized for voice over broadband and short-loop applications.

"In developing the industry's first fully integrated, standards-based IAP for shared tenant environments, Netensity designed in Legerity's Intelligent Access chipsets because they offer integrated features we need, such as line testing and diagnostics, while adhering to stringent carrier-class standards," said Arlan Harris, president and chief executive officer of Netensity, Inc. "We value Legerity as a communication IC partner because they share our goal of enabling widespread deployment of integrated ADSL and voice services."

"Netensity's innovative AdvanEdge 1212 platform offers a technological breakthrough for service providers who want to deliver bundled data and voice services to business and residential subscribers in higher-density environments," said Daryl White, president and CFO of Legerity. "Our Intelligent Access chipsets provide Netensity with enabling semiconductor technology for broadband, multi-service access solutions designed for the growing MTU and MDU markets in North America, Europe, and Asia."

Netensity's innovative approach to broadband access combines Asynchronous Transfer Mode (ATM) switching, packetized voice, DSL multiplexing, and "plain old telephone service" (POTS) technologies in a highly integrated platform. By incorporating these technologies into a low-cost-of-entry Customer Located Equipment (CLE) platform, the AdvanEdge 1212 functions as a "virtual central office," enabling incumbent and competitive access service providers to provision voice and ADSL access to residential and business subscribers over existing single-pair telephone wiring without the local loop distance limitations and deployment roadblocks associated with traditional voice and DSL provisioning.

About Legerity's Intelligent Access Voice Solutions

Legerity's Intelligent Access Voice Solutions are multiple-line chipsets designed to reduce the cost per line by integrating system functions, such as ringing and advanced test capabilities, that would otherwise require external hardware. The Intelligent Access family includes a wide range of IC products optimized for varying communication application requirements. Dual and Quad ISLAC devices are low-voltage CMOS ICs that provide A/D and D/A conversion, filtering, equalization, hybrid balance, companding, supervision, ringing and test functions, and interfaces to an external microprocessor and the digital backplane. ISLIC devices are high-voltage bipolar ICs that drive a single subscriber line, maintain longitudinal balance, and sense line conditions.
