Abstract
A software definable DLC architecture ( ) based on high speed analog-to-digital converters ( ) and digital signal processors ( ) capable of sampling to at least several MHz. Multiple copper pair wires ( ) are attached to a single DSP ( ) and upbanding is applied at staggered intervals so that all copper pairs reside in distinct spectral bands. Signals arriving from a single copper pair is sampled and digitized within the spectral band associated with each subscriber side service. The encoded digitized result is transmitted back to the central office ( ) for decoding into the relevant signaling scheme according to the type of service attached to the subscriber ( ).
