Abstract
Power-line communication (PLC) systems collect information over power lines from end-point devices respectively associated with customer sites, for assessment by a central processing circuit operated on behalf of a power utility company. In the PLC system, each of a number of PLC data-collector circuits includes a plurality of data interface units and PLC end-point device data computation circuit. Typically, one data interface circuit is located proximate, and another is distal, the location of the computation circuit. Each data interface unit includes a transformer circuit for selectively receiving data from a subset of the end-point devices via the power lines, a transformer-coupling circuit for selectively sending data to the subset of the end-point devices via the power lines, and a high-throughput data driver circuit for outputting data in accordance with a data-transfer protocol which is common to the other high throughput driver circuits which operate in accordance with the data-transfer protocol.
