Title :
Line fault prediction and location in echo cancelling data transmission systems

Abstract :
Theoretical and practical results are presented which show that the tap coefficients of an echo cancelling modem can be used as an aid to line fault prediction and location. It is indicated that in some cases it is possible to identify a line fault before the transmission performance is seriously impaired.
