Abstract: A system and method for testing lines to determine service-affecting conditions on a line, such as telephone wiring. Conditions may be identified from low frequency variations in a frequency spectrum measured on the line. The line may be stimulated with a broad spectrum signal, such as may be generated by a DSL modem operating in the LO state or may be the result of noise on the line. Analysis of the low frequency variations may yield information about the nature of service- affecting conditions allowing conditions, such as un-terminated or poorly-terminated extensions to be identified. The method may be performed by a test device attached to premises wiring in a telephone network and used to determine whether the premises wiring will support VDSL2 or other high speed data services without modification or may indicate changes at the premises to enable the wiring to support high speed data services.

Abstract: A system for testing a conductor of a structure can include a test device connected to the conductor. The test device is configured to test an electrical characteristic of the conductor and to produce a test result based at least in part on the electrical characteristic. A service provider network may be configured to communicate with the test device to initiate a test and/or to obtain the test result. A customer may use a computing device to obtain information regarding the test result, as well as guidance for troubleshooting and resolving a problem detected with the electrical conductor, such as a fault.

Abstract: In an apparatus and method of testing the capacity of a network to support DSL services, a test device is coupled to a pair of wires (e.g., Tip-Ring) that support DSL services between ATU-C and ATU-R modems. In operation, the test device: samples for a DC line feed or potential on the wires when the ATU-R and ATU-C modems are operatively connected via the wires; samples for AC noise present on the wires when the ATU-R modem is electrically isolated from the ATU-C modem which is operatively coupled to the wires; samples for DSL signals output by the ATU-R modem when the ATU-C modem is electrically isolated from the ATU-R modem; and samples for DSL signals on the wires when the ATU-R modem is operatively coupled to the ATU-C modem via the wires. Based on these samples, the test device determines the capacity of the network to support DSL services.
