  • Patent number: 9118544
    Abstract: A method and apparatus for providing automated processing of a switched voice alarm on a switched and/or Internet Protocol (IP) network are disclosed. For example, the method receives an alarm associated with a switched voice service, and retrieves a Local Routing Number (LRN) or Primary Inter-exchange Carrier (PIC) information from a switch serving a call associated with a caller's telephone number. The method determines if the alarm is due to one or more service degradations, and notifies a work center responsible for one or more of the service degradations if the alarm is due to the one or more service degradations.

  • Patent number: 8869173
    Abstract: A method and system for adaptive processing of alert messages exchanged between applications is disclosed. The system may include a diagnostic engine coupled to a plurality of applications. A plurality of application alert messages may be monitored to determine if the alerts exceed a predetermined threshold. If a threshold number of alert messages is exceeded, an interface status based on a diagnostic code for the interface may be determined. A query value for the interface may be adjusted. Based on the amount of the increase in the alert messages, different actions may be indicated. An administrator for the application interface or for equipment associated with the interface may be notified for servicing the equipment.

  • Patent number: 8705371
    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: 8539496
    Abstract: Method and apparatus for configuring systems implementing diverse platforms in a network is described. In one example, functional units of the systems are exposed to define abstract function signatures. A template is specified using at least one of the abstract function signatures to define at least one executable task. The template is translated into configuration data adapted to configure each of the system to collectively perform the at least one executable task. The configuration data is applied to the systems through a coupler layer adapted to interface with each of the diverse platforms.

  • Patent number: 8504319
    Abstract: Methods, systems, and products maintain reflective maintenance records for a network. Test results are mirrored from different testing applications to a centralized testing database. The test results are associated to circuit identifiers. A work order is received that identifies trouble associated with a customer. A circuit identifier associated with the customer is retrieved and, prior to performing a test of a circuit to resolve the trouble, the centralized testing database is queried for the circuit identifier. A test result associated with the circuit identifier is retrieved and the work order is updated with the test result.

  • Patent number: 8457006
    Abstract: Embodiments of the present invention are directed to diagnosing problems in a dual stack network supporting Internet Protocol Version Six (IPV6). Inventoried information can be retrieved from an inventory system in response to a problem associated the dual stack network. It can be determined whether a mismatch exists between live customer address information associated with a customer edge router and the inventoried information. A notification can be generated in response to determining whether a mismatch exists. The notification includes information representing a cause of the problem and resolution of the problem.

  • Patent number: 8194639
    Abstract: A method and apparatus for providing automatic processing of an alarm related to a multicast service in a network are disclosed. For example, the method receives an alarm related to a multicast service, and retrieves multicast data, wherein said multicast data comprises one or more of: a source Internet Protocol (IP) address for a source, a group IP address, and Protocol Independent Multicast (PIM) data. The method retrieves interface information, wherein the interface information comprises one or more of: an interface IP address, a PIM mode, and a Designated Router (DR) IP address. The method retrieves a status of a neighbor of the source in accordance with the source IP address, and determines if a neighbor is established for the source IP address.

  • Patent number: 8169922
    Abstract: A system and method directed to diagnosing a problem associated with a route group in a network are disclosed. A problem associated with a route group is diagnosed by comparing inventory information associated with a route group to current route information associated with a router, where the router is associated with the route group. The process followed for diagnosing a problem associated with a route group depends on whether there is a mismatch between the inventory route information and the current route information.
