ABSTRACT:
A method and apparatus implements a Virtual Exchange Reference Impact (VERI) technique to define a pattern to shape the spectrum of a cabinet deployed system to minimize its impact, e.g., FEXT, into an exchange deployed system while achieving effective cabinet system performance, e.g., in terms of data transmission rate. The invention shapes the cabinet system to replicate a self-impact of the exchange system on itself based on the known distance of the cabinet from the exchange. The shaping is required when both exchange and cabinet systems share the same bundle and exhibit overlapped bandwidths. A particular example consists of VDSL deployed from remote cabinet impacting ADSL2/ADSL2+ deployed from the exchange.
