20080266127 | PREDICTING CABLE FAILURE THROUGH REMOTE FAILURE DETECTION OF ERROR SIGNATURES - Computer systems and techniques for predicting a cable failure in a network system begin by receiving a remote alarm indicator followed by a remote alarm indicator clear as a transmission alarm indicator of an intermittent short duration failure on the transmission path of a circuit. If the transmission alarm indicator is of a duration less than or equal to a preset threshold D it is considered an acceptable short hit transmission alarm. When at least N acceptable transmission alarms have been received and the time stamps of the last N acceptable transmission alarms have been recorded, then a determination is made as to whether N acceptable transmission alarms have been received within a preset time period. A moving window time period is calculated as the difference between the time stamp of the present acceptable transmission alarm K and the time stamp of the [(K−N)+1] acceptable transmission alarm. If the difference is less than or equal to T, a cable error signature is indicated. Based on the cable error signature, a cable failure may be predicted. | 10-30-2008 |
20090290498 | AUTOMATIC PROBLEM ISOLATION FOR MULTI-LAYER NETWORK FAILURES - A method and apparatus includes automatically correlating indicators already generated by network components to detect and isolate failures that are caused by or related to network components operating on different layers of the open system interconnect (OSI) model. Failure indicators that persist for longer than a specified time window are automatically detected and correlated with one another based on a topology table. The method uses indicators already generated by the network components, obviating the need for software that typically resides on and consumes valuable processing time of network components. | 11-26-2009 |
20100080147 | METHODS FOR RECONCILING TRUNK GROUP IDENTIFICATION INFORMATION AMONG VARIOUS TELECOMMUNICATION NETWORK MANAGEMENT SYSTEMS - A method includes retrieving a first data set from a switch within a network, the first data set including a set of switch records. Among the switch records included in the first data set is a first switch record associated with and including a field identifying a first trunk group from a set of trunk groups included within the switch. A second data set is retrieved from a configuration management system configured to facilitate an operation associated with the network. The second data set includes a plurality of configuration records, which includes a first configuration record associated with and including a field identifying the first trunk group. When the field included in the first configuration record differs from the field included in the first switch record a report is produced. | 04-01-2010 |
20100114786 | WORKLIST INTEGRATION OF LOGICAL AND PHYSICAL TASKS - In accordance with a method of managing work flow, tasks associated with a telecommunications service order from a plurality of worklists of computing source systems are merged into a merged worklist. Each computing source system maintains a respective worklist that includes a task associated with the service order. The tasks of the service order in the merged worklist are prioritized into a prioritized sequence to be completed on a work-when-ready basis. An error in completion of a task associated with a worklist of a source system is detected and a new task to correct the detected error is generated. Further, the worklist of the source system associated with the detected error is updated with the new task and the new task is integrated into a proper position of the prioritized sequence in the merged worklist in accordance with the work-when-ready basis. | 05-06-2010 |
20120036219 | SYSTEM AND METHOD FOR EVENT DRIVEN PUBLISH-SUBSCRIBE COMMUNICATIONS - The present invention provides a system and a method for delivering an event from an event publisher to an event subscriber via an event broker. The event broker performs several functions such as receiving an event published by an event publisher of a first domain, assigning a priority based on a second domain to a plurality of subscribers of the second domain, processing the event based on a rule and the priority, and further delivering the event published by the event publisher of the first domain to the plurality of event subscribers of the second domain in accordance with the priority. | 02-09-2012 |
20130013470 | METHODS FOR IDENTIFYING AND RECOVERING NON-REVENUE GENERATING NETWORK CIRCUITS ESTABLISHED OUTSIDE OF THE UNITED STATES - A method includes issuing a retrieval instruction, such as a database query, to retrieve from a database system a datum associated with a network circuit established outside of the United States. Upon receiving the datum from the database system, it is determined, based on the datum retrieved, whether the network circuit is incurring a charge. It is further determined, based on the datum retrieved, an amount of revenue generated by the network circuit. When the amount of revenue generated by the network circuit is below a predetermined threshold, a termination instruction to terminate a service associated with the network circuit is issued. | 01-10-2013 |
20130014283 | DATABASE APPLICATION SECURITY - A method allows access to a set of secure databases and database applications over an untrusted network without replicating the secure database. The method involves authenticating a user using a first authentication application. When the user is verified, then the user's credentials are directed to a second authentication application associated with a secure database based on a first set of user settings retrieved for the user. The second authentication application, based on a second set of user settings, grants the user access to the secure database and database applications associated with the secure database. | 01-10-2013 |
20130028101 | METHOD AND APPARATUS FOR PROVIDING SIGNATURE BASED PREDICTIVE MAINTENANCE IN COMMUNICATION NETWORKS - A method and apparatus for collecting and processing line performance data transmitted over cables, e.g., Y-cables, is disclosed. The present invention applies a method based on specific performance measurements, specific measurement time intervals, and compare results from different measurement time intervals to produce a “signature” that indicates deteriorating performance of a particular Y-cable. Once a “signature” is detected, the method will proactively and automatically generate a trouble ticket to trigger the dispatch maintenance staffs to service the cable, e.g., to perform the replacement of the Y-cable in question, thus completing the predictive maintenance process. A trouble ticket is a record used to report and manage the resolution of network related problems. | 01-31-2013 |
