摘要： A test system for testing a pair of telecommunications access networks, e.g. as part of transfer engineering. The system comprises a test head for connection, via an access arrangement, to first and second access networks. In a first phase, the access arrangement is arranged to connect the test head to the first access network for sending a first request from the tester to, for example, a CLI server via the first access network. The first request comprises a parameter associated with a user line. The tester is arranged to receive in response to the first request a first identifier from the server. In a second phase, the access arrangement is arranged to connect the test head to the second access network for sending a second request from the test head through the second access network to, for example, a CLI server. The second request also comprises the parameter. The tester is arranged to receive, in response to the second request, a second identifier from the target server and is arranged to carry out a comparison operation involving the first and second identifiers received in response to the two requests. A mismatch can indicate a fault or misconnection in either access network or a problem with network configuration data.

摘要： A fault is located along a telecommunications line between the network terminating equipment and the local exchange by measuring a change in the capacitance of the line when compared with the capacitance under normal operating conditions. A geographical information system is used to plot all possible routes for the line between the terminating equipment and the exchange, and the most probable route is selected based on the known positions of nodes along the line, such as pole mounted distribution points and streetside cabinets. The distance of the fault along the line is then plotted along the most probable route to determine an accurate fault location, which is given to a field technician as the location of the nearest premises or a grid reference.

摘要： 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 includes probability calculation to establish the location of a fault measured 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. A lowest valid capacitance value provides an estimate of the reference capacitance between the exchange and the node. A histogram is compiled of historic fault values and a new fault is compared against the histogram 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.

摘要： 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.

摘要： 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. A lowest valid capacitance value provides an estimate of the reference capacitance between the exchange and the node. 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.
