摘要： 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.

摘要： 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.

摘要： 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.

摘要： An optical distribution node is provided. The optical distribution node includes a laser transceiver that is coupleable to at least one fiber optic link. The optical distribution node communicates upstream and downstream digital data with the head end over the at least one fiber optic link. The optical distribution node further includes a data concentrator coupled to the laser transceiver. Further, for each of at least one coaxial cable link, the optical distribution node includes a frequency translator and a node modem. The frequency translator receives and translates the upstream digital data from modems on the at least one coaxial cable link to a different carrier to provide a signal to the modems on the at least one coaxial cable link for collision detection. The node modem is coupled between the coaxial cable link and the data concentrator. The node modem demodulates upstream digital data for the data concentrator and modulates downstream digital data for transmission over the coaxial cable link.

摘要： A power takeoff inductor is an inductor comprised of a hybrid core. Materials with varying low and high permeabilities are combined to create a common hybrid core for the inductor. The inductor can be used in power transmission systems where signals of lower frequencies are transmitted along the same conductors with signals extending across a broad range of higher frequencies. The inductor is used to extract signals having low frequencies without degrading other high frequency signals.
