    • A TDD radio unit and a real-time RX supervision method used therein are provided. The method comprises steps of : setting the radio unit into an RX supervision status in a TX timeslot, wherein the setting comprises : connecting a TX observation module in the radio unit to a termination port of a Transmit/Receive (TR) switch in the radio unit; and setting all components in the RX path in a power-on status; detecting a gain of the TX observation module by means of a signal from the TR switch passing through the TX observation module and a gain of the RX path by means of a TX leakage signal passing through the RX path; calculating a gain difference between the TX observation module and the RX path; and comparing the calculated gain difference with a preset gain difference to determine a state of the RX path. With the TDD radio unit and RX supervision method, the TX leakage signal is used, and thus no extra simulation source is need. Furthermore, a real time supervision is performed.
    • 提供了TDD无线电单元和其中使用的实时RX监视方法。 该方法包括以下步骤:将无线电单元设置为TX时隙中的RX监视状态,其中该设置包括:将无线电单元中的TX观察模块连接到无线电中的发送/接收(TR)交换机的终接端口 单元; 并将RX路径中的所有组件设置为开机状态; 通过通过TX观察模块的TR开关的信号和通过RX路径的TX泄漏信号的RX路径的增益来检测TX观测模块的增益; 计算TX观察模块和RX路径之间的增益差; 以及将所计算的增益差与预设增益差进行比较,以确定RX路径的状态。 使用TDD无线电单元和RX监控方法,使用TX泄漏信号,因此不需要额外的模拟源。 此外,执行实时监控。

    • An Ethernet ring includes a plurality of participating nodes with adjacent ones of the nodes coupled together via an independent link. At least two of the nodes are ERP protocol compliant and at least one of the nodes is ERP non-compliant node. Failures in the Ethernet ring are mitigated by determining whether a failure detected at a ring port of one of the ERP compliant nodes is a direct failure on the link coupling the ring port to an adjacent one of the nodes or at the adjacent node, or is an indirect failure on another link or at one of the ERP noncompliant nodes. The ring port is blocked if the failure is determined to be direct so that communication at the ring port remains unblocked if the failure is determined to be indirect. An indication is provided for indicating whether the ring port is blocked or unblocked in response to the failure.
    • 以太网环包括多个参与节点,其中相邻节点经由独立链路耦合在一起。 至少有两个节点符合ERP协议,并且至少有一个节点是ERP不合规节点。 通过确定在符合ERP的节点之一的环形端口处检测到的故障是否在将环形端口耦合到相邻节点或相邻节点的链路上是直接故障来减轻以太网环路中的故障,或者是 在另一个链接或其中一个ERP不合规节点上的间接故障。 如果故障被确定为直接,则环形端口被阻塞,以便如果确定该故障是间接的,则环形端口上的通信将保持未阻塞。 提供指示是否响应于故障来指示环形端口是否被阻塞或解除阻塞。
