Accelerated MSAPs and IADs Enable In-Building Delivery

of Bundled Voice and Data Services in MTU Applications

WCA 2000 -- Accelerated Networks (NASDAQ:ACCL) will join Siemens Carrier Networks LLC, a wholly owned subsidiary of Siemens Information and Communication Networks Inc. at this year's Wireless Communications Association conference in New Orleans to demonstrate a multiservice broadband access network solution for wireless carriers.

Accelerated's multiservice access platforms (MSAPs) allow multiple services to be delivered over in-building wiring using symmetrical DSL (SDSL) technology, which is well-suited for business-oriented multi-tenant unit (MTU) environments. Accelerated's family of integrated access devices (IADs) provide connectivity to customer-premises voice and data equipment, allowing high-quality delivery of multimedia applications all the way to the desktop.

"We believe that the combination of LMDS wireless systems and DSL-based multiservice broadband access equipment provides an efficient and robust solution for wireless carriers focused on MTU applications," stated Suresh Nihalani, president and chief executive officer of Accelerated Networks. "Siemens' ability to integrate all of the components necessary for robust and seamless broadband wireless solution allows wireless carriers to rapidly exploit the value of their LMDS licenses."

The specific products from Accelerated Networks in the WCA 2000 demonstration include the AN-3204 MSAP concentrator and the AN-30 IAD. The AN-3204 is a compact DSL concentrator, ideally sized for MTU applications, providing connectivity to the P-Com 28Ghz ODU at bandwidths up to 155Mbps, and further providing connectivity to in-building wiring using SDSL at symmetrical bandwidths up to 2.3Mbps. The AN-30 IAD, a member of Accelerated's range of IADs, provides connectivity to subscriber analog or digital telephony equipment and Ethernet or frame relay data devices. Integral echo cancellation, voice compression, silence suppression and comfort noise insertion allow as many as 24 high-quality voice lines to be delivered over a single copper pair, in addition to high-speed Internet access, frame relay access and IP VPNs.

The complete system is part of Siemens Quickstream(TM) broadband wireless access solution. Accelerated Networks and P-Com are Siemens technology partners. According to Fred Fromm, president and CEO of Siemens Carrier Networks LLC, "Quickstream brings wireless and wireline solutions together, integrating the infrastructure technology with content and applications. It's an ideal way for carriers to address business customers with individually tailored solutions."
