A-L offers “green” VDSL
In keeping with the trend toward making networks more energy-efficient, Alcatel-Lucent introduced a DSL platform it says will enable service providers to consume up to 25 percent less power compared with conventional DSL solutions.
As the product conforms to ETSI standards, it is designed for the European market.
A-L believes it to be the first commercially available VDSL platform for ETSI markets that, through the use of channel bonding, can deliver 50Mbs to all users (with peaks up to 100Mbs).
"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."
