Telekom Austria Rolls with Vectoring from Alcatel-Lucent

Telekom Austria will deploy vectoring technology from Alcatel-Lucent to deliver significantly higher data transmission speeds on its domestic Giga-Network. Vectoring technology minimizes the impact of interference or “crosstalk�? between copper lines in a copper bundle.


Telekom Austria's A1 group is initially deploying vectoring in Korneuburg, lower Austria. A comprehensive countrywide rollout is planned for the second half of 2012.


With the world’s first commercial launch of VDSL2 Vectoring technology, Alcatel-Lucent has demonstrated once again its technology leadership. Based on cutting-edge innovation from our research center Bell Labs, the VDSL2 Vectoring technology marks a further important step in our efforts to get the utmost out of the current network infrastructure and thus create real added value for network operators such as A1 and their customers,�? said Stephen Carter, President, Europe Middle East and Africa for Alcatel-Lucent.

“The still untapped potential of copper lines is incredibly impressive. Since the late 1990s, when private households started to use modems for data transmission, we have been able to reach a thousendfold increase in transmission capacities of existing copper lines. We are currently facing a dual challenge: on the one hand, we have to invest in the further rollout of our high-performance fiber optic network going forward, and on the other, we have to provide our customers with a full-coverage broadband network with ever-increasing bandwidths starting from today," stated Walter Goldenits, CTO, A1.

  • In September 2011, Alcatel-Lucent introduced a VDSL2 vectoring solution capable of delivering 100 Mbps over existing copper loop lengths of 400 meters.

    VDSL2 vectoring uses digital signal processing to remove crosstalk between copper pairs in a bundle, similar to noise cancellation in headphones. From line cards at the central office or DSLAM, the system measures the crosstalk from all the lines in the bundle and then generates an anti-phase signal to cancel out the noise. For this solution, Alcatel-Lucent developed its own chipset and software. It began field trials in 2010 with a number of operators, including Belgacom, A1 Telekom Austria, Swisscom, Orange, P&T Luxemburg and Türk Telekom.


    Alcatel-Lucent's VDSL2 Vectoring solution includes both Board-level Vectoring (ideal for small nodes) and System-Level Vectoring options for the company's existing ISAM DSLAM platforms, including the 7356 ISAM, the 7330 ISAM and the 7302 ISAM. The new products include a 48-port Board Level Vectoring card, a 48-port System Level Vectoring card, and a Vector Processing card supporting 192 ports initially and expanding to 384-ports of system level vectoring in 2012.
