20130286852 | Estimating Physical Locations of Network Faults - A method of estimating a physical location of a network fault is provided. Information is received concerning the physical topology of the network by data pulls of information concerning network components and terminal network elements and geographic locations thereof. A network fault is detected by monitoring at least one performance parameter transmitted via upstream communications from the terminal network elements, and a physical location of a network fault is estimated based on the performance parameter, the physical topology of the network, and the terminal network element or elements from which the performance parameter was received that indicated the network fault. A list of network components that require inspection and that may provide a source of the network fault is generated. A signal processing electronic device for mapping the network fault and a non-transitory computer readable storage medium having computer program instructions are also provided. | 10-31-2013 |
20130290783 | Estimating a Severity Level of a Network Fault - A method of estimating a level of severity of a network fault is provided. Performance parameters are monitored on upstream and downstream links to terminal network elements on a network to detect potential network faults. An alarm is raised with respect to a potential network fault automatically if at least one of the performance parameters as monitored crosses a preset threshold. After an alarm is raised, a level of severity is assigned to the alarm based on pre and post forward error correction (FEC) bit error rates (BER). In addition, the total number of terminal network elements that are impacted by the network fault is estimated and, when multiple alarms are raised of an equal level of severity, a higher priority is placed upon an alarm that affects service to a greatest number of terminal network elements. | 10-31-2013 |
20130290791 | Mapping a Network Fault - A method of mapping a network fault is provided. Information is received concerning geographical coordinates of terminal network elements and their association with shared network components. A performance parameter is transmitted via upstream network communications from the terminal network elements is monitored. Terminal network elements from which the monitored performance parameter are unacceptable relative to a predetermined threshold for the performance parameter are identified, and a cluster of terminal network elements estimated to be subject to a common network fault is defined. The cluster includes terminal network elements that are identified as reporting an unacceptable performance parameter, as being within a predetermined geographic distance from each other, and as being associated with a common shared network component. A geographic map is populated with a single cluster alarm and includes an identification of the terminal network elements within the cluster. An electronic device and non-transitory computer readable storage medium are provided. | 10-31-2013 |
20140269869 | METHOD USING EQUALIZATION DATA TO DETERMINE DEFECTS IN A CABLE PLANT - A method of estimating a defect location within a network is provided. Information of pre-equalization coefficients of an adaptive pre-equalizer of a terminal network element on the network is received. A total amount of equalization applied by a negative delay portion of the adaptive pre-equalizer relative to a main tap level and a total amount of equalization applied by a positive delay portion of the adaptive pre-equalizer relative to the main tap level is determined. The terminal network element is determined as being affected by a defect if at least one of the total amount of equalization applied by the negative or positive delay portions relative to the main tap level is at an unacceptable level. If a defect is identified, a location of the defect is estimated differently depending upon whether the negative or positive delay portion of the adaptive pre-equalizer applies the greatest amount of equalization. | 09-18-2014 |
