The fact that existing copper loops can facilitate 300Mbps at 400metres reshapes the whole next-generation broadband competitive environment - and will open up a wide range of new business opportunities for 'traditional' DSL players.<br><br>"This announcement shows that Alcatel-Lucent is seriously looking at all possible innovations to help its customers speed up the deployment of next-generation access networks, through a smart mix of advanced copper and fibre technologies."<br><br>If the technology can be commercialised economically within the next few years it could have a significant impact on Australia's NBN. Clearly the possibility of its network being able to deliver 100Mbps via DSL to customers 1km from the exchange would considerably increase the competitive threat the Telstra's existing network could pose to the NBN.<br><br>The throughput was achieved using a technology called "DSL Phantom Mode". Gee Rittenhouse, head of Research for Bell Labs, suggested that it has very real commercial possibilities.<br><br>"What makes DSL Phantom Mode such an important breakthrough is that it combines cutting edge technology with an attractive business model that will open up entirely new commercial opportunities for service providers, enabling them in particular, to offer the latest broadband IP-based services using existing network infrastructure."<br><br>According to Alcatel-Lucent, "At its core, DSL Phantom Mode involves the creation of a virtual or 'phantom' channel that supplements the two physical wires that are the standard configuration for copper transmission lines."<span class="Apple-converted-space"> </span><br><br>'DSL Phantom Mode' appears to be a new phrase coined by Alcatel-Lucent - a Google search produced no references that could not be traced back to Alcatel-Lucent's press release - and the company's 'explanation' throws little light on what it is or how it works.<br><br>"Bell Labs' innovation and the source of DSL Phantom Mode's dramatic increase in transmission capacity lies in its application of analogue phantom mode technology in combination with industry-standard techniques: vectoring that eliminates interference or 'crosstalk' between copper wires, and bonding that makes it possible to take individual lines and aggregate them."<br><br>The demonstration took place in a laboratory and Alcatel-Lucent says: "Further research is being conducted to refine deployment models and determine a specific set of customer premises equipment models compatible with the DSL Phantom Mode technology."<br><br>However equipment vendors, and telcos, have long held out the promise of boosting DSL bandwidth by bonding together two or more pairs, using a technique known as dynamic spectrum management.<span style="color: rgb(0, 32, 96);
