    • A bus connection detector circuit used for a switching network comprising a plurality of semiconductor switch elements of PNPN semiconductor four-layered structure, which are arranged in a matrix array and adapted to conduct upon the application of a potential thereacross. A plurality of diodes are connected at their one end to horizontal and vertical buses, respectively, and connected at their other end in common to one end of a voltage regulating diode for detection of the potential of the buses, and the other end of the voltage regulating diode is connected to a voltage level sensor, thus making up a single bus connection detector circuit, so that the connection of each bus can be detected by the single bus connection detector circuit.
    • 一种用于交换网络的总线连接检测器电路,包括PNPN半导体四层结构的多个半导体开关元件,它们以矩阵阵列排列并且适于在施加其上的电位时进行导通。 多个二极管的一端分别连接到水平和垂直总线,并在其另一端共同连接到电压调节二极管的一端,用于检测总线的电位,另一端的电压 调节二极管连接到电压电平传感器,从而构成单总线连接检测器电路,使得每个总线的连接可以由单总线连接检测器电路检测。

    • In a switching network having cross-points constituted by semiconductor switch elements of four-layer structure of PNPN, communication channels are connected in an unbalanced configuration, and all vertical or column buses and horizontal or row buses constituting the switching matrix are individually grounded through respective capacitors, whereby the semiconductor switch elements are inhibited from erroneous firings due to application of voltages having a high raise-up rate such as high frequency noises, thereby to protect the switching network from erroneous switching operations without increasing cross-talk.
    • 在具有由PNPN的四层结构的半导体开关元件构成的交叉点的交换网络中,通信信道以不平衡配置连接,构成开关矩阵的所有垂直或列总线和水平或行总线通过相应的单独接地 电容器,由于由于施加了诸如高频噪声的高升高速率的电压而使得半导体开关元件被禁止发生错误,从而在不增加串扰的情况下保护开关网络免于错误的开关操作。
