    摘要： Methods and apparatus to characterize a digital subscriber line (DSL) subscriber loop are disclosed. An example method comprises selecting a portion of a search space based on a measured transfer function response, the search space defining a plurality of combinations of transmission line parameters, and identifying a characterizing parameter of a digital subscriber line (DSL) subscriber loop from the selected portion of the search space, the characterizing parameter having an associated transfer function that substantially corresponds with the measured transfer function response.

    摘要： A dual-mode broadband modem operative to operate in a service mode and a surveillance mode is disclosed. Generally, the dual-mode broadband modem comprises a primary communication device; a secondary communication device; a central processing unit in communication with the primary and secondary communication devices; and a memory unit in communication with the central processing unit. In the service mode, the primary communication device communicates with a broadband service provider and the central processing unit stores historical information regarding performance of the primary communication device in the memory unit. If an interruption in broadband service is detected, or the performance of the primary communication device falls below a predetermined threshold, the dual-mode broadband modem switches to surveillance mode and the secondary communication device is activated. The secondary communication device communicates with the broadband service provider to send at least a portion of the historical information regarding performance of the primary communication device to the broadband service provider for processing to determine a source of the interruption in broadband service or a source of the decreased performance of the primary communication device.

    摘要： A system and method for imputing data into a database includes an imputing system operable to impute data based on outside plant construction principles. The imputing system includes an inventory database, a data engine, a search engine, and a loop engine. The inventory database includes a plurality of distribution records each associated with one or more cable pairs. The data engine determines if a desired distribution record corresponding to a desired cable pair includes missing data. The search engine searches a known class of serving terminals for complete distribution records and iteratively searches a sized binder group within the inventory database for one or more complete distribution records where the size of the binder group searched increases with each iterative search. The loop engine determines an imputed value for the desired distribution record based on the searching and imputes the value into the desired distribution record.

The method includes, during training of a broadband modem, sending a series of tones within a frequency transmission band of the broadband modem, receiving the transmitted series of tones at a receiving broadband modem, receiving a measurement value, determining a transmission loss for each of the series of tones by comparing the predetermined transmission power level, and the received measured power level, performing a statistical match comparison between each of the received tone signals and a plurality of different computer models of a single transmission facility having various bridge taps connected to the single transmission facility, and determining a best fit between each of the received tone signals and one of the plurality of the bridge tap computer models. The series of tones have a predetermined transmission power level.
