Patent number: 8634324Abstract: 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.Type: GrantFiled: September 13, 2012Date of Patent: January 21, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: David Lu, Hossein Eslambolchi, Paritosh Bajpay, John McCanuel, Roberta Bienfait, Carolyn Bekampis, Mihail Vasilescu, Mark Rogaski, Wen-Jui Li, Mohammed Shariff, Thomas Dickey, John Soares

Patent number: 7847701Abstract: 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.Type: GrantFiled: July 1, 2008Date of Patent: December 7, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Paritosh Bajpay, Carolyn V.

Patent number: 7822417Abstract: Systems and methods for predicting one or more service problems in a communication network are described. In one implementation, a threshold is set and signal data are collected at an interface component. The collected data are compared to the threshold, and depending on the comparison between the collected data and the threshold, a trend analysis is performed on the collected data.Type: GrantFiled: December 1, 2005Date of Patent: October 26, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Hossein Eslambolchi, John McCanuel, Paritosh Bajpay, Mihail Vasilescu

Publication number: 20100014855Abstract: A system and method is disclosed that detects the onset of failing optical subnetwork network elements and minimizes the volume of Performance Monitoring (PM) parameter data that must be acquired and trend across a provisioned path by monitoring digital (SONET/SDH) section PM parameter data first, which is used to trigger an examination to determine which optical subnetwork is experiencing degradation. Threshold Crossing Alerts (TCAs) are set for digital section PM parameter data and when a digital section PM parameter is greater than or equal to its TCA, the method identifies which subnetwork is degrading. Once a subnetwork is identified, analog PM parameter data is acquired for network elements employed in the identified subnetwork and determines from monitoring the network elements' analog PM parameter data the network element(s) that is degrading. A maintenance ticket is issued identifying the failing network element(s).Type: ApplicationFiled: July 21, 2008Publication date: January 21, 2010Inventors: Christopher Arnone, David H. Lu, James J. Robinson, Andrew Van Kraanen, Mihail Vasilescu

Publication number: 20090226174Abstract: A system and method is disclosed that parses WDM subnetworks and collects TL1 Performance Monitoring (PM) parameter data from subnetwork network elements (NEs) and applies a set of comparisons to discover under-performing equipment according to predetermined operating thresholds. The comparisons examine NE pump laser baseline values, deviations, efficiency, tilt error, span loss and calculated expected optical power.Type: ApplicationFiled: March 4, 2008Publication date: September 10, 2009Inventors: Anamaria Csupor, Clarence D. Paul, James J. Robinson, Charles Schneider, Mihail Vasilescu

Patent number: 7315181Abstract: Systems and methods for detecting errors in communication networks are described. When an interface component is potentially defective, a rules engine performs diagnostic testing to determine if the interface component is defective. During diagnostics, the rules engine tests a protection interface card to determine if it is defective before determining if the interface component is defective.Type: GrantFiled: December 1, 2005Date of Patent: January 1, 2008Assignee: AT&T Corp.Inventors: Hossein Eslambolchi, John McCanuel, Paritosh Bajpay, Mihail Vasilescu
