Abstract
A method for remotely detecting at a ground station failed multiplexors and radio transceivers in an airborne telephone system is disclosed. Usage activity of the devices is predicted using a normalized gaussian distribution. A three prong test examines actual usage activity of the multiplexors and radio transceivers which is normalized and compared with that predicted utilizing a chi-square analysis with a specified confidence interval to detect abnormalities in the usage activity.
