Nokia today became one of the first global DSL suppliers to announce the availability of a standards-based VDSL (very high speed digital subscriber line) line card using a DMT (discreet multitone) chipset. The line card is deployable in Nokia’s new-generation broadband access platform, the Nokia D500, and can also be installed into the Nokia D500 remote access module.
The line card is being introduced at the Broadband World Forum in Berlin and the PT/ Expo Comm in Beijing. The fully integrated VDSL solution will be available for commercial trials towards the end of the year.
The Nokia VDSL line card implements the DMT line code and is compliant with the ITU-T 993.1 VDSL standard, supporting both 997 and 998 band plans with 3 or 4 bands. The line card allows operators and service providers to offer symmetric services, providing up to 10 Mbps service to businesses, as well as asymmetric services, providing 22 Mbps downstream and 3 Mbps upstream for high bandwidth services such as video on demand and digital broadcast TV.
Each VDSL line card supports 24 ports and allows both packet and ATM data transport over VDSL loops in the hardware design. As part of the family of Nokia D500 line cards, the 24-port VDSL DMT line card provides high-speed service solutions for business and residential customers, meeting their increasingly bandwidth-intensive requirements.
“VDSL allows operators to support a diverse range of services including residential media services, such as video on demand, digital broadcast TV, and interactive TV, as well as improved business-oriented high-speed data services, such as high-end LAN interconnection for small to medium enterprises and small-office home-office businesses,” says Mark Slater, Vice President. Sales and Marketing, Broadband Systems, Nokia Networks. “These services will be important in helping operators drive the overall profitability of broadband services and thus increase average revenue per broadband user.”
DMT line coding is particularly suited to the deployment of VDSL-based services in the local loop. Crosstalk and RF interference can be much more acute in central office and remote site based solutions, and DMT offers specific features and functionalities to reduce the affect of such interference. Having a DMT solution in the access network helps provide for future interoperability between multiple line technologies.
