Abstract: A method and apparatus are disclosed in which defect behavior in an integrated circuit is discovered and modeled rather than assuming defect behavior in the form of a fault. A plurality of tests are performed on an integrated circuit to produce passing and failing responses.

Abstract: A method and apparatus for detecting a fault in a joint connecting sections of an electrical transmission line together are disclosed. Previously known methods for detecting joint faults require a visual inspection of the joint or testing the transmission line using sophisticated, expensive equipment. This manual testing is expensive and inefficient. In the proposed method, a fault in a joint (301) connecting sections of an electrical transmission line (107) together is detected by measuring the resistance to current flowing through the joint (301) in one and the other directions along said electrical transmission line (107) and detecting a fault in the joint (301) if the measured resistance differs substantially in said one and the other directions. The method has particular utility in relation to low power transmission lines such as telephone lines.

Abstract: A fault location system for a telecommunications network including a local exchange or switch, a node such as a primary connection point and a plurality of line terminations to the customer includes probability calculation to establish the location of a fault measuring from the exchange. Historical non-faulty reference values of capacitance are compiled for each line passing through the node providing a measure of the distance of each line.

Using various parameters, probability tables are compiled of historic fault values and a new fault is compared against these tables to establish the probability of it being a fault at the node or elsewhere. As a result the reference capacitance can be obtained without the need for an engineer at the node, and the likely location of a fault can be pinpointed with greater accuracy.
