  • Patent number: 8159942
    Abstract: The application discloses a system and a method of selecting a profile of a digital subscriber line. In a particular embodiment, the method includes setting a threshold for voice quality and determining a number of acceptable code violations that can occur without compromising the voice quality of the digital subscriber line. When the actual number of code violations exceeds the determined number of code violations an alternate profile is selected for the DSL line.

  • Publication number: 20120040665
    Abstract: Devices, systems, and methods are disclosed for managing text-based services on mobile devices during the operation of a vehicle. Proactive service-controls use a time of day and location based services to determine that a mobile device is in a moving vehicle. Reactive position-awareness techniques use near-field communication (NFC) to determine that the mobile device is being operated by a user in a driver's seat of the vehicle. Upon satisfying both these determinations, specific text-based services such as messaging, browsing, etc. can be disabled by either the mobile device itself or by a network entity. The present invention can also be extended to managing other mobile device's usages in vehicles, including phone calls, online gaming, etc.

  • Patent number: 8102902
    Abstract: A system and method is described for determining a condition of a communication line, such as the absence of a filter device on a digital subscriber line (DSL). A first signal characterized by a high upstream power is activated over the line, and a first set of parameters associated with the communication line is obtained. A second signal characterized by a low upstream power is activated, and a second set of parameters associated with the communication line is obtained. Comparison of first and second sets of parameters is indicative of a condition of the connection and presences or absence of a DSL filter on the communication line.

  • Publication number: 20110228665
    Abstract: A method includes detecting, at a customer premises equipment (CPE) device, a problem associated with a network device. The network device is communicatively coupled to the CPE device via a local area network. For example, the CPE device may include a residential gateway (RG). The method includes determining, at the CPE device, whether the problem associated with the network device is locally correctable. When the CPE device determines that the problem is locally correctable, the method includes initiating a corrective action to resolve the problem. When the CPE device determines that the problem is not locally correctable, the method includes sending data associated with the problem from the CPE device to a network system via a wide area network.

  • Patent number: 7903790
    Abstract: 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.
