  • Patent number: 8107381
    Abstract: A service provider unit automatically diagnoses problems in an Ethernet network that are associated with layers 1, 2, and/or 3 and determines whether there is a problem associated with an Ethernet gateway switch EGS. Further diagnostics can be performed to determine the layer, type, and/or location of the problem(s) based on whether there is a problem with the EGS. The diagnostic process followed depends on the types of problem(s) in the network. Once the problems have been diagnosed, an operator can be notified of the location and/or type of problem.

  • 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: 7956737
    Abstract: Trouble ticket management automates existing institutional operational processes by engaging various external trouble ticketing systems. These systems feed correlated alarm events, trouble analysis results, and trouble ticket information to a particular institutional network. Correlated alarm feeds, including trouble ticket information, are correlated and sent to institutional trouble ticket management systems. The alarms are processed and remedy tickets are created. The remedy tickets interact with remedy tickets at the institutional trouble ticket management systems. These remedy tickets are bonded with maintenance platform tickets.

  • Patent number: 7818283
    Abstract: A business process automation system architecture is used to isolate problems in a virtual private network access network. Codified rules and a rules based program are used to determine all equipment from a customer premises equipment to a VPN core access point equipment on a VPN access path and that is associated with a failure. The codified rules also govern the gathering of information on the equipment including determining whether the equipment supports automated diagnostics and the communication protocols used. Extended PING testing is done on the equipment and a status of the extended PING test, link status, line protocol status, and existing loop status is determined. Further testing is automatically run based on the codified rules and the status. The failure is then isolated to the CPE, a local exchange carrier, or a network provider.
