Infineon´s QAM-VDSL Solution Fully Supports ETSI´s VDSL Standard: Dual-Line Code Allows Carriers To Choose Best Products For Deployment

Jul 2, 2003 | Market News

Munich, Germany – July 2, 2003 – Infineon Technologies (FSE/NYSE: IFX) today announced that its Quadrature Amplitude Modulation (QAM) VDSL chip set fully supports the newly revised European Telecommunications Standards Institute (ETSI) VDSL standard specifications. The ETSI TM6 sub committee has decided to revise the VDSL standard to support dual-line code. This proposal is expected to be adopted and published by ETSI as planned during July 2003.

ETSI’s VDSL standard, first approved in February 2001, specifies both QAM and DMT (discrete multi-tone) as acceptable modulation techniques, leaving the choice of this single aspect of VDSL technology up to the market. Additionally, a large number of European operators recently expressed their support for a dual line-code standard with an important contribution at the June 2003 T1E1.4 standardization meeting. The contribution in support of dual line code for VDSL can be found at the following URL:

“ The clear statement of support for dual line code made by major European operating companies demonstrates their commitment to promote free market choice for VDSL technology,” said Christian Wolff, Vice President of Infineon’s Wireline Communications Business Group and General Manager of the Access Business Unit, “The best way to accelerate VDSL deployment is to encourage true competition, in which component choice is based on price, performance, silicon size, and vendor reputation. Rather than leaving the market to a single chip vendor with limited field experience, ETSI supports that line code selection should be made by the carriers. To date, solutions chosen by most equipment providers and carriers are based on QAM VDSL.”

QAM-VDSL systems make up more than 95% of all VDSL deployments in the world. Infineon has shipped over 4 million QAM-VDSL ports, representing more than 2.5 million active lines. This makes Infineon’s QAM VDSL the number one VDSL solution in the world today.
