DSL dispersed up to 100 Mbit / s?

Several years ago, the firm. ASSIA. - Author and developer of the software ( software) technology for Dynamic Spectrum Management (DSM) and the corporation. Ikanos. - A leading developer of chips for the technology, have entered into an agreement pursuant to which ASSIA Ikanos and pledged to develop in 2011... 2012, a set of integrated circuit. NodeScale Vectoring system. The latter would allow to increase considerably ( by about half, to 100 Mbit / c) the possibility of high-speed VDSL2 modems, and thus greatly expand the introduction of combined copper and optical -type scenario FTTx (FFTB, FTTC, FTTN etc) in the networks of broadband access ( BBA). Moreover, ASSIA was to develop software, and Ikanos - himself a set of integrated circuit.

And the first report of success: in Fremont (California, USA), September 20, 2011 the first official demonstration of VDSL2 equipment with new set of integrated circuit NodeScale Vectoring system. The latter contains a linear map NodeScale Vectoring, processors Vector Computation Engines and Components for the modem user, corresponding to the standard G. 993/5 (formerly known as G. vector).

Our reference.
In systems. DSL. the main obstacle is the mutual influence of transition between pairs of the cable bundle. In this case the main parameters of the lines DSL - bandwidth (or speed ), and overlapped length are calculated for worst-case transient effects, as they have considerable scatter and virtually underestimated.

The method of dynamic spectrum management DSM ( we are talking about the spectrum of crosstalk ) can significantly reduce ( and ideally and practically suppress the interference ). This is due to this suppression and obtained a significant gain in the parameters of DSL lines. Naturally, the DSM method is an automatic method does not require the intervention of operating personnel.

DSM method includes 4 levels, which are complicated with the number. In the present design uses third level of DSM, called Vectoring. This explains the presence of the word in the title of a set of integrated circuit.
