ADSL2 plugfest 2003 
DURHAM, N.H.--(BUSINESS WIRE)--July 16, 2003-- 
Ten ADSL2 Chipset Developers Push Towards Increased Bandwidth For 
Enhanced Broadband Applications Offered By ADSL2 Physical Layer 
Interoperability Progress 
The DSL Forum announced the success of its second multi-vendor
ADSL2 "plugfest" interoperability event conducted at the end of June
in conjunction with the University of New Hampshire's InterOperability
Laboratory (UNH-IOL) in Durham, NH. At the DSL Forum-sponsored
interoperability plugfest, ten ADSL2 chipset developers performed
three basic physical layer tests, defined in the DSL Forum's internal
"Proposed Draft 013 - Interoperability Test Plan for ADSL2 Plugfests"
"The strong attendance and performance at this second ADSL2
'plugfest' event provides evidence that the DSL industry is geared up
to fight for the triple play space--voice and data as always, and now
especially video," said Tom Starr, president of the DSL Forum. "Our
role is to broaden DSL interoperability and reach, to ensure effective
broadband support of emerging applications and content. ADSL2 is a
fundamental element in achieving the next major steps in delivering
DSL benefits to mass markets around the world and plugfests such as
this are vital for expediting these DSL advancements." 
ADSL2 (also known as ITU Recommendation G.992.3) is the new
standard that was approved by the International Telecommunications
Union (ITU) in August 2002. It provides numerous improvements over
existing ADSL standards including line diagnostics, power management,
power cutback, reduced framing and online configuration. The ITU has
also recently approved the ADSL2plus standard, which builds on ADSL2
by expanding the bandwidth to approximately 2 MHz and increasing
achievable data rates to more than 20 Mbps. 
Scott Valcourt, Managing Director of the University of New
Hampshire InterOperability Laboratory comments: "The increased
participation levels and great success in terms of G.hs and
initialization interoperability clearly demonstrate that ADSL2 as a
technology is steadily advancing and becoming increasingly
interoperable on a worldwide scale, with ADSL2plus closely on its
PD-013 is a testing suite that provides three basic physical layer
tests to ensure interoperability between multiple chipsets and systems
supporting ADSL2. Test results were gathered through the use of
technical analyses, one specific to Central Office (CO) solutions, and
one specific to Customer Premises Equipment (CPE) solutions. The
plugfest results showed immense progress. 
The ten silicon companies participating in the most recent ADSL2
plugfest were: 
Analog Devices, Inc. (NYSE: ADI) 
Aware, Inc. (NASDAQ: AWRE), 
Broadcom Corporation (NASDAQ: BRCM) 
Catena Networks 
Centillium Communications, Inc. (NASDAQ: CTLM) 
Infineon Technologies AG (FSE/NYSE: IFX) 
GlobespanVirata, Inc. (NASDAQ: GSPN) 
Realtek Semiconductor Corp. 
Samsung Electronics Co, Ltd. 
Texas Instruments Incorporated 
A third plugfest for ADSL2 chipsets is scheduled for the week of
August 4, 2003, followed by a plugfest open to all ADSL2 system
vendors-- DSLAM, CPE, testing equipment, and chipset developers are
all expected to participate-- to test extensions to the ADSL2,
including ADSL2plus and Reach Extended ADSL2 standard the week of
August 11, 2003, both at the UNH-IOL.

About the University of New Hampshire InterOperability Laboratory 
The University of New Hampshire InterOperability Laboratory
(UNH-IOL) is a non-profit organization that currently offers
comprehensive interoperability and conformance-based testing services
in the following network technology areas, individually know as
Consortiums: 10Base-T, 10 Gigabit Ethernet, ADSL, Bridge Functions,
DOCSIS, Fast Ethernet, Fibre Channel, Gigabit Ethernet, IPv6, iSCSI,
MPLS, Power over Ethernet, Routing, SHDSL, VDSL, and Wireless. The
mission of the UNH-IOL is two-fold: to educate and train undergraduate
and graduate students from the University of New Hampshire in specific
technology areas, and to provide a neutral multi-vendor environment
for the purpose of identifying and solving complex interoperability
problems. The test solutions that are created at the UNH-IOL offer a
set of methods to increase interoperability through protocol
operations, signaling, point-to-point and multi-system scenarios.
