Abstract: Systems and methods for classifying interference in data signals received by a terminal device (or other end-user or endpoint device) transacting data in a data transfer network are disclosed. Embodiments include defining an array of signal quality metrics at the terminal device, where each signal quality metric is associated with a subcarrier of a data channel used to transfer data with the data transfer network. The array of signal quality metrics may be input to a classification model and the classification model may output a type, sources, and/or cause of disruptions such as interference identified in the signal quality data. In some cases, the output may include frequency characteristics such as a center frequency and/or bandwidth of the identified signal disruption. The terminal device may transmit a message to an upstream device of the data transfer network, which may indicate the identified interference.

Abstract: Grafting segments of a network together to mitigate service disruptions associated with impairments, maintenance, etc., is contemplated. The grafting may include instantiating a wired and/or wireless graft to facilitate connecting an impaired portion of a network to an unimpaired portion, such as to reestablish services at the impaired portion via the graft to the unimpaired portion.

Abstract: Methods, systems, and devices for wireless communications are described. A user may select a cable modem (CM) at a graphical user interface (GUI) of a network device for testing. The network device may receive the indication of a selected query from GUI and transmit the selected query to the CM. The network device may receive a response message from the CM and compare the response message to an expected response message. The network device may generate a report indicating a status of the CM based on the comparing. The status of the CM may relate to a compliance of the CM to a standard. Additionally or alternatively, the status of the CM may indicate a performance level of the CM.

Abstract: A proactive operations (ProOps) platform is contemplated to facilitate processing data for purposes of turning included information into action, such as to enable operators to proactively manage network operations using information derived from mathematical analysis of raw data collected from network devices.
