  • CHANNEL INTEGRITY METRIC CALCULATION
    Publication number: 20080170508
    Abstract: A first device (102), associated with an electrical substation, for example, automatically transmits a plurality of echo requests to a second device (104) that is in communication therewith by way of a communications channel (106). The second device (104) responds to the echo requests, and the first device (102) determines parameters relating to the echo requests, such as round trip times. The first device (102) calculates a channel quality metric as a function of the determined parameters.
