Telecom Leaders to Collaborate On Standard-Based HDSL2 Effort for Business Access Market RESTON, Va.--(BUSINESS WIRE) via NewsEdge Corporation -- Leaders in Digital Subscriber Line (DSL) technology announced today that they are collectively endorsing HDSL2, a high-performance symmetric, standard-based DSL service for the business access market segment. In order to accelerate the deployment of HDSL2, 3Com Corporation, Alcatel, FlowPoint Corporation, Level One Communications, Netopia and Nortel Networks are publicly endorsing this new two-wire transmission technology. Comprised of both central office (CO) and customer premise equipment (CPE) manufacturers, the group intends to develop products incorporating HDSL2 technology. The equipment vendors will work together, using the University of New Hampshire's (UNH) Interoperability Lab to ensure interoperability among CPE and CO based equipment. The addition of small-to-medium business-focused HDSL2 technology to the local loop will allow Local Exchange Carriers (LECs) the ability to offer a full suite of symmetric DSL services for businesses. The draft proposed American National Standard for HDSL2 was developed by ANSI accredited Committee T1 and is now out for voting and comment. In addition, the International Telecommunications Union (ITU) is working on an international standard, referred to as G.shdsl, for this technology. The companies will base their work on the ANSI HDSL2 standard and progress towards G.shdsl when available. HDSL2 is currently designed to deliver T1-quality symmetric service over a single copper pair. The ITU G.shdsl effort intends to build upon this base technology to deliver a multi-rate symmetric service over extended reaches for maximum business coverage. "It is critical that the leaders in the DSL market place work together to drive standards. Standards translate to interoperability and this reduces stranded assets for customers. With this HDSL2 announcement, key participants in the supply chain for DSL service have agreed to endorse HDSL2. Our customers, and the entire market, will benefit from these efforts," said Mike Dobbs, VP/GM Alcatel ADSL. "As a long-standing interoperability advocate, 3Com Corporation fully supports efforts to establish a universal HDSL2 standard," said Joe Celia, product line manger for 3Com's network systems business unit. "As demand for high-speed Internet access grows, HDSL2 could provide seamless, high-bandwidth connectivity solutions to small and medium businesses worldwide." "Netopia is pleased to endorse HDSL2, as we believe that the move towards standardization and interoperability will provide many new business opportunities for DSL customer premises equipment vendors such as Netopia," said Michael Trupiano, senior vice president and general manager, Netopia Internet Equipment Division. "HDSL2 will allow our service provider partners to offer DSL service that is as powerful as leased line technology and substantially more cost-effective." "The enthusiasm that we are seeing for our HDSL2 chip set is evidence of the demand by service providers for this high-speed, symmetric and interoperable technology," said Dr. Robert Pepper, vice president, Intel's Network Communications Group, and general manager, Level One Communications, Inc. "We are working closely with our key customers to provide more highly integrated, lower power, standards compliant chipsets that will help enable widespread deployment of HDSL2 in early 2000." The HDSL2 line code, known as TC PAM, is designed to overcome some the limitations of today's Symmetric DSL (SDSL) offerings based on 2B1Q line codes. In addition to the increasing concern about 2B1Q-based SDSL solutions' degradation of coexisting services, they are not formally standardized, making them vendor-specific and not interoperable. HDSL2's TC PAM line code is more "spectrally friendly" to coexisting services while allowing for longer reach and higher data rates.
