A first component with a first common connection, a first A branch, and a first B branch, the first common connection is connected to the first network terminal. A second component has a second common connector and a second A and B branch. The second common connector is connected to the second network terminal. The third component has a third A and B branch and one third common connector. The third A branch is connected to the first A branch. The third B branch is connected to the second B branch. The third common connector is connected to a first device terminal of a device. The fourth component has a fourth A and B branch and a fourth common connector. The fourth B branch is connected to the second B branch. The fourth common connector is connected to a second device terminal of the device. The fourth A branch is connected to the first A branch. One or more of the first, second, third and fourth components is chosen to be a switch or splitter and configured to change the flow of electromagnetic power through the first and second terminals of the device and the first and second network terminals.

    • The invention is a broadband network monitoring system and method. The system has one or more RF carrier generators that generate one or more generator signals, called a reference signal, each of the generator signals having a generator signal frequency. One or more RF transient detectors sense a line signal on one or more broadband lines in the broadband network. Each line signal has one or more test signals applied by a remote RF carrier generator. Each test signal has a frequency equal to one of the reference signals. Each RF transient detector senses and compares the test signal and the reference signal in various ways to produce a transient indicator when the test signal and reference/generator signal are not the same. The transient indicator indicates that there may be a perturbation or some other problem in the respective broadband line. A controller is connected to each of the RF transient detectors and controls an RF switch and an analyzer. The RF switch has two or more inputs connected to each respective RF detector and one output connected to the analyzer. When the controller receives a transient indicator, it controls the switch to connect the broadband line producing the transient indicator to the analyzer and, in a preferred embodiment, starts the analyzer. In this way, all of the broadband lines can be monitored and analyzed for perturbations using a single analyzer.
    • 本发明是一种宽带网络监控系统及方法。 该系统具有一个或多个RF载波发生器,其产生称为参考信号的一个或多个发生器信号,每个发生器信号具有发生器信号频率。 一个或多个RF瞬态检测器感测宽带网络中的一个或多个宽带线路上的线路信号。 每个线路信号具有由远程RF载波发生器施加的一个或多个测试信号。 每个测试信号具有等于参考信号之一的频率。 每个射频瞬态检测器以各种方式检测并比较测试信号和参考信号,以便在测试信号和参考/发生器信号不相同时产生瞬态指示。 瞬态指示符表示相应宽带线路中可能存在扰动或其他问题。 控制器连接到每个RF瞬态检测器,并控制RF开关和分析器。 RF开关具有两个或更多个输入,其连接到每个相应的RF检测器,一个输出连接到分析器。 当控制器接收到瞬态指示器时,它控制开关将产生瞬态指示器的宽带线连接到分析器,并且在优选实施例中,启动分析器。 以这种方式,可以使用单个分析仪监测和分析所有宽带线路的扰动。

    • One or more novel switch controllers are used in a network of network devices to connect and disconnect to one another. The switch can be any general purpose computer that has one or more communication links that connect one or more outputs of the computer to one or more of the network devices. In the computer, the network is represented by a directed graph that has two or more nodes and one or more directional edges connecting one or more pairs of the nodes. Each node in the pair represents a device that is connected/disconnected (represented by the edge of the directed graph.) One or more commands are associated with each edge that is used to connect the network devices represented by the nodes that the edge connects. When connecting the connected source to the connected sink, the computer executes a routing process that searches the directed graph to find the nodes associated with both the connected source and the connected sink and a path between the connected source and the connected sink through the directed graph (network). The computer executes a connection process that traverses the path and performs each command associated with each of the edges along the path so that the network devices operate to form a connection between the connected source and the connected sink along the path.
