Abstract:
For a communication system that employs interconnected communication components and defines a communication pathway running through the communication components and through interconnections therebetween, the communication pathway having test points, an apparatus for performing diagnostic tests on the communication system comprises testing agents residing on-board the communication components, and a test controller, coupled for communication over the communication pathway. The test controller includes a test signal apparatus coupled to send a test signal over the communication pathway, detectors, coupled to the test points, for sensing communication activity at the test points responsive to the test signal, and a communication activity analyzer, coupled to receive communication activity information from the detectors, for analyzing the received communication activity information to identify a fault and isolate a communication component containing the fault.
