NodeScale Vectoring cancels noise
across an entire network node from 192 to 384 ports or more, meeting the
deployment requirements of the world's leading service providers. With Ikanos'
algorithms, compression and coding techniques, service providers can deliver
100 Mbps performance at the scale necessary to support their growing subscriber
bases via a cost-effective commercial silicon and software solution.
NodeScale Vectoring was designed from inception to address the need for delivering
100 Mbps performance across an entire service provider network. The complete
system includes NodeScale Vectoring compatible line cards, Vector Computation
Engines and G.vector-ready customer premises equipment. The system can be
deployed flexibly to increase the performance of existing VDSL nodes, as part
of ADSL network upgrades and in copper plants that previously served only plain
old telephone service (POTS). Since the same Ikanos chipset supports vectored
and non-vectored deployments, upgrades can occur on a line-by-line basis for a
pay-as-you-go vectored network deployment.
Ikanos' NodeScale Vectoring complies with the
International Telecommunication Union standards group (ITU-T) G.vector standard
(G.993.5), which provides for dynamic spectrum management level 3 (DSM-3)
through the use of advanced crosstalk cancellation techniques.
