System employing XDSL spectrum relocation

The invention relates generally to a digital subscriber loop (DSL) system which utilizes un-shielded twisted pair (UTP) or shielded twisted pair (STP) for network connection to customer premises equipment (CPE) through a network interface device (NID) and standard (i.e., in-home) wiring using coaxial cable for CATV and UTP for Plain Old Telephone Service (POTS). The invention also relates to a DSL system which uses a passive NID-based end station and an active CPE-based end station for spectrally relocating xDSL frequency signals to lower noise locations on customer premises wiring. A coaxial-based communication system connects network-side xDSL services to xDSL CPE devices and avoids interference from a noise spectrum that is degrading to xDSL performance or emission compliance on either the network or customer premises sides on the NID. The system provides an NID and a CPE interface device at the two ends of the coaxial wiring to perform a spectral relocation of the xDSL signal to a lower noise frequency band than is used for the xDSL service. Interfaces to the system are industry standard xDSL, POTS, and CATV services, while the transport medium is the normal coaxial type wiring and CATV splitters found on the customer premise.
