  • Patent number: 7774237
    Abstract: A method for identifying high-risk orders associated with a customer that includes the steps of: receiving an order that includes a customer number, an order type and a plurality of entries; identifying a customer contract based on the order type and the customer number, the customer contract having a plurality of terms that correspond to the entries; comparing the entries to corresponding terms using rules; and identifying a high-risk order containing at least one error from the comparison. The method can also include assigning a result code or a result text to the order, which corresponds to the errors that are identified, and changing the rule set by adding or removing rules.

  • Publication number: 20100157815
    Abstract: A system and method provides transport independent automated voice solutions. The method comprises receiving an indication of a network issue of a network. The network issue relates to a malfunction of a voice service provided by the network. Sub-networks of the network utilize a plurality of transmission protocols. The method further comprises determining a source of the network issue by determining a status for each of select components related to the network issue. The select components are determined by a type of the transmission protocols related to the network issue.

  • Publication number: 20100161769
    Abstract: Described herein are systems and methods for automatically troubleshooting problems related to Media Access Control (“MAC”) address limit problems within a virtual local area network (“VLAN”). An exemplary method includes identifying a media access control (“MAC”) address alert within a network, referencing a translation table of a plurality of MAC addresses to detect a whether a number of MAC addresses in the network exceeds a threshold number, and providing a solution for the MAC address alert. An exemplary system includes a rules building engine for identifying a media access control (“MAC”) address alert within a network, referencing a translation table of a plurality of MAC addresses to detect a whether a number of MAC addresses in the network exceeds a threshold number, and providing a solution for the MAC address alert.

  • Publication number: 20100149994
    Abstract: A data communications system may include a network having a plurality of network provider routers configured to support Open Shortest Path First (OSPF) circuits between customer edge routers outside the network, an automated diagnostic system coupled to the network provider routers. The automated diagnostic system may be configured to automatically initiate one or more inquiries of one or more of the network provider routers in response to a customer IP address identifying a customer edge router servicing a customer location from which a service failure has been reported and a circuit address identifying an Open Shortest Path First (OSPF) circuit related to the reported service failure.

  • Publication number: 20090161549
    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.

  • Publication number: 20090138588
    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.
