摘要： Using timing delays and values associated with plant information between a CMTS, R-PHY device or a remote MACPHY device and user devices on a network to determine the distance between a head end device, for example a CMTS, R-PHY device or a remote MACPHY device and an end-user device such as cable modem in order to alert to a stolen, outdated, misplaced or otherwise at-risk end-user device.

摘要： A Data Over Cable Interface Specification (DOCSIS) node includes a first DOCSIS port and a second DOCSIS port. The node also includes a plurality of radio frequency (RF) ports. A plurality of client devices can be coupled to the RF ports. A RF switching network is coupled between the first DOCSIS port and the second DOCSIS port, and the plurality of RF ports. One or more control circuits can switch the RF switching network between at least a first state and a second state. The switching of the RF switching network allows the one or more control circuits to identify which client devices are coupled to which RF ports of the node.

摘要： Devices, systems and methods that reduce funneling noise in upstream data transmissions from modems providing the transmissions through respective RF legs connected to the node. Preferred devices and systems may include a node that is configured to selectively isolate respectively scheduled upstream data signals from noise present on any RF leg not propagating a scheduled upstream data signal.
