ALU Introduces high-capacity "green" DSL

Alcatel-Lucent today launched the market’s first true high-capacity and eco-efficient digital subscriber line (DSL) platform – enabling service providers to deliver tomorrow’s applications over their installed copper base, all while consuming up to 25% less power compared to conventional DSL solutions.

Alcatel-Lucent’s revolutionary green DSL leverages the reduced power consumption of its latest generation of DSL line cards, the company’s unique distributed DSLAM concept and Alcatel- Lucent’s Smart DSL technology.

“Today, standards exist that allow modems to go in a low-power mode when user traffic is low. However, re-activating these modems causes power fluctuations – resulting in crosstalk and destabilizing the network,” said Jürgen Lison, Vice-President of Alcatel-Lucent's ISAM product unit. “Alcatel-Lucent’s green DSL provides operators with a unique, end-to-end solution that overcomes these issues – enabling a significant reduction of the modems’ power consumption across a service provider’s subscriber base without causing any line stability issues. This is avalue proposition that cannot be provided by any other vendor in the industry today.”
 

Not only does Alcatel-Lucent’s latest ISAM release support a significant power reduction compared to conventional DSL solutions, it is also the first commercially-available DSL platform
for ETSI markets that delivers 50Mbs to all users – with peaks up to 100Mbs - anywhere in the network because of its new, high-capacity, very high-speed DSL (VDSL) line cards and its support of VDSL bonding technology across the line card. This ISAM release incorporates the company’s third generation of VDSL line cards, highlighting Alcatel-Lucent’s innovative technology and market leadership in the DSL space, while supporting its applications enablement strategy through physical layer synchronization for mobile backhaul and enhanced support for business services.

“Release-4 of the ISAM platform puts Alcatel-Lucent more than one year ahead of its competitors,” said Dave Geary, President of Alcatel-Lucent’s Wireline Networks activities. “The
ISAM platform enables our customers to deliver the most bandwidth-intensive services over their copper architectures, by leveraging – for instance - last-mile bonding support, which is a first in ETSI markets. We are confident that our ‘more bandwidth with less power’ value proposition will again create a big stir in the DSL industry – just as the launch of the ISAM platform five years ago.”

This release supports Alcatel-Lucent’s comprehensive eco-sustainability program that includes using innovation to build smarter, eco-sustainable networks at all layers (access, transport and core) with a framework that addresses hardware, software, network and site innovation.
