High speed access system over copper cable plant

Abstract

A system for transporting a high speed data stream over a plurality of relatively low bandwidth unshielded twisted copper pairs within the local loop plant or in any environment having a plurality of copper lines. A transmit data processor may perform scrambling, FEC encoding, and interleaving on the data before it is divided and dispatched to the plurality of modem elements for transmission over the local loop plant, either bidirectionally or unidirectionally. On the receiving side, the individual data streams are collected, aggregated, and a receive data processor performs de-interleaving, FEC decoding and de-interleaving, resulting in the high speed data stream originally transmitted. The system also may include crosstalk cancellation, power and PSD control, data raze control and optimal routing of the transmitted signals within the twisted pair binders. The system may optionally multiplex a plurality of low bandwidth telephony services over the high speed link using either TDM or FDM techniques.
