    • A circuit arrangement, for serial data transmission via at least one bus, is made up of plural subscriber stations each having a time circuit, by means of which faulty seizure of the bus can be discontinued. In order to achieve the highest possible level of availability with a comparatively large number of subscriber stations, the bus is connected to a data transmission network via a coupling device which itself includes a time circuit for the discontinuation of faulty seizures of the data transmission network by the bus. The circuit arrangement can be used advantageously in monitoring devices of electrical information transmission technology in which a plurality of stations each containing a plurality of locating devices are connected to a control processor.
    • 用于经由至少一个总线的串行数据传输的电路装置由多个用户站组成,每个用户站具有时间电路,借此可以停止总线的错误检测。 为了通过相对大量的用户站实现最高可用性的可用性,总线通过耦合设备连接到数据传输网络,该耦合设备本身包括用于通过以下方式停止数据传输网络的故障发作的时间电路 公交车。 电路装置可以有利地用于监视电信息传输技术的设备,其中将包含多个定位设备的多个站点连接到控制处理器。

    • A data transmission facility comprises a central station and a plurality of substations connected thereto via a data bus, the substations outputting a control signal dependent on the transmission or reception condition thereof. A plurality of substations are therefore capable of being connected to a serial point-to-point interface of the central station by way of a coupling device which is reversible with respect to the direction of transmission by optional activation or deactivation of level converters on the basis of control signals transmitted by the central station or by the substations. The data transmission facility is particularly suited for the transmission of operating state signals from intermediate locations of a communications transmission facility to a central evaluation facility.
    • 数据传输设备包括中央站和经由数据总线与其连接的多个变电站,变电站根据其发送或接收条件输出控制信号。 因此,多个变电站能够通过耦合装置连接到中央站的串行点对点接口,耦合装置可以通过基于电平转换器的任意激活或去激活而相对于传输方向是可逆的 由中心站或变电站发送的控制信号。 数据传输设备特别适用于从通信传输设施的中间位置向中央评估设备传输操作状态信号。
