Abstract

A technique is described whereby a communication carrier detect and disable device is used in broadband local area networks (LANs). The concept improves on circuitry designed to detect malfunctioning devices in that it not only provides detection capabilities, but provides a disablement feature to offending communication adapters. This improvement eliminates the need of operator intervention and provides an uninterrupting feature for an entire communication network. Typically, broadband LANs allow computers to communicate with each other over a single cable and utilize a frequency spectrum divided up into six-megahertz-wide channels, similar to television cable networks, and generally occupy two channels, one for transmitting and one for receiving.
