The International Telecommunication Union (ITU) has finalised the new technical specifications for triple play services at speeds up to 10 times faster than standard ADSL.
The ITU recommendation for very-high-bit-rate digital subscriber line 2 (VDSL2) will allow operators to compete with cable and satellite providers by offering triple play services such as video-on-demand, high speed Internet access and advanced voice services over a standard copper telephone cable.
The VDSL2 standard, which delivers up to 100Mbps both up and downstream, not only addresses the growing consumer demand for high-speed multi-media services, but is also interoperable with existing DSL equipment and should work with both legacy ATM networks and next-generation IP-based networks.
"We have leveraged the strengths of ADSL, ADSL2+ and VDSL to achieve the very high performance levels you will see with the new VDSL2," says Yoichi Maeda, chairman of the ITU Telecommunications Standardisation Sector Study Group.
"The new standard will be an extremely important feature of the telecommunications landscape, and is a landmark achievement for those players that are relying on this recommendation to take their businesses to the next level."
Maeda claims that the new VDSL2 Recommendation (ITU-T G.993.2) is ready for immediate deployment and should help to foster competitive global markets for high-speed equipment, while assuring a level playing field for developers and vendors.
