Alcatel-Lucent’s new DSL gear consumes 25% less power

| July 3, 2009

Alcatel-Lucent has launched what it calls a “high-capacity and eco-efficient” DSL platform, which now consumes 25% less power than conventional DSL solutions. According to the company, the ‘green DSL’ platform leverages increased energy efficiency of its latest generation DSL line cards, a unique distributed DSLAM concept, and something called 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 Jurgen 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 a value proposition that cannot be provided by any other vendor in the industry today.”

In addition to energy savings, Alcatel-Lucent claims that the new platform is the first commercially-available DSL platform for ETSI markets that delivers 50Mbps to all users with the ability to peak up to 100Mbps via its support for VDSL and VDSL bonding technology across line cards. The company did not specified the product number of the new platform.

“Operators challenged by recessionary and fiber business case limitations want to optimize investment in their existing copper networks while also offering sustained higher bandwidth over an extended reach. In conjunction with the expected growth of FTTB, VDSL2 remains an important option to support higher bandwidth services to residences and enterprises and for mobile backhaul,” noted Kamalini Ganguly, broadband analyst at Ovum, Inc. “The new release of Alcatel-Lucent’s ISAM platform addresses the operator constraints and objectives we have noted in our research. Our research further shows that greener access technologies are a critical need for operators, and lower-power products are a critical component of meeting this need.”
