Techniques for determining conditions of power lines in a power distribution system based on measurements collected by a plurality of sensor units deployed in the power distribution system. Techniques include obtaining first transformed data associated with a first set of one or more measurements collected by a first sensor unit in the plurality of sensor units and second transformed data associated with a second set of one or more measurements collected by a second sensor unit in the plurality of sensor units, and determining, by using at least one processor and based at least in part on one or more features calculated from the first transformed data and the second transformed data, at least one condition of at least one power line in the power distribution system.

In a method of testing a residential broadband communication network, a residential gateway or set top box (STB) performs one or more single-ended parametric tests of the residential network that runs therebetween. The residential gateway or STB also performs one or more single-ended reflectometry tests of the residential network that runs therebetween. The residential gateway and the STB perform one or more dual-ended tests of the residential network that runs therebetween. The residential gateway dispatches the results of the foregoing tests to either: a device on the residential network, a device of another network that supplies broadband services to the residential network, or an intelligent device coupled to the residential gateway.

A test system and method for performing DSL assessments of a telephone line along a prescribed test path is disclosed. The disclosed test system and method includes a loop diagnostic test unit adapted for testing said telephone line using narrow-band and mid-band frequency test signals; a test system controller and a test system server to provide the DSL assessments to a user via an appropriate interface. In addition, the disclosed analysis methods utilize primary line condition information, secondary line condition information, historical line information, together with real-time measurements and external data inputs to perform line imbalance analysis, fault identification analysis, trend analysis, and jurisdictional analysis all of which have relevance to quality, performance and assurance of DSL service through the telephone line.

A system and method for performing DSL assessments of a telephone line along a prescribed test path is disclosed. The disclosed system includes a loop diagnostic test unit adapted for testing said telephone line using narrow-band and mid-band frequency test signals; a test system controller and a test system server to provide the DSL assessments to a user via an appropriate interface. In addition, the disclosed methods include the basic steps of: accessing the telephone line along the test path that includes selected hardware such as a voice switch test bus, central office splitter, service provider instruments and terminations; ascertaining various line characteristics along the test path using mid-band and narrow-band frequency signals; analyzing the line characteristics to identify line conditions that affect DSL service; and determining the impact of the line conditions on DSL service.

A system and method for testing lines in a network. The system and method are described in connection with a system for use with a telephone network to aid a network operator determine whether the any line can support high speed data services. According to the method, a mapping is created between low frequency measurements and average loop loss over a high frequency range. The average loop loss is sued to compute the equivalent working length of a line, which is an industry standard measure of the ability of a line to support high speed data services.
