Abstract
A communication isolation system is provided that may employ error correction techniques for the data communicated across an isolation barrier used for connecting electronic circuitry to a communication line. In one embodiment, each data bit to be transmitted to or from the phone line may be transmitted three times across an isolation barrier so that it is possible to withstand a single electronic fast transient event. In another embodiment, the isolation barrier may be a capacitive isolation barrier. In another embodiment, the three transmissions of the data bit may be received across the isolation barrier and delay elements utilized to provide the data bits to a logic circuit in a synchronized fashion so that the three data bits may be compared to determine the error corrected data.
