SYSTEMS AND METHODS FOR COMMUNICATING AMONG NETWORK DISTRIBUTION POINTS

摘要

A communication system has a trunk extending from a network facility, such as a central office, with a plurality of distribution points positioned along the trunk. Each leg of the trunk defines a shared channel that permits peak data rates much greater than what would be achievable without channel sharing. As an example, the connections of each respective trunk leg may be bonded. Further, the same modulation format and crosstalk vectoring are used for each leg of the trunk. The crosstalk vectoring cancels both far-end crosstalk (FEXT) that couples between connections of a given trunk leg and crossover crosstalk that couples between one trunk leg and another. In addition, logic determines an amount of excess capacity available for each leg of the trunk and controls error correction based on the determined excess capacity.

主权项

1. A communication system, comprising:
a first distribution point positioned along a trunk extending from a network facility, the first distribution point having a first service unit coupled to a first plurality of communication connections of the trunk and configured to receive from the first plurality of communication connections a plurality of data flows destined for customer premises (CP) transceivers at a plurality of customer premises, each of the first plurality of communication connections shared by each of at least a first plurality of the CP transceivers; and a second distribution point positioned along the trunk and having a second service unit coupled to the first service unit via a second plurality of communication connections of the trunk, each of the second plurality of communication connections shared by each of at least a second plurality of the CP transceivers, wherein the first service unit is configured to employ crosstalk vectoring to cancel crosstalk affecting signals communicated across the first plurality of communication connections, and wherein the first service unit is configured to employ crosstalk vectoring to cancel crosstalk affecting signals communicated across the second plurality of communication connections.
