摘要： A method of restoring an active path between two nodes of a transport network upon occurrence of a failure includes the steps of determining an alternate path through the network and establishing a path protection involving the failed active path and the alternate path. If in layered networks, a failed path is restored at a lower layer and at a higher layer concurrently, the restoration actions in the higher network layer can thus be reverted easily.

摘要： The invention relates to a remote interface device (12) for terminating a remote optical fiber link, with a network input (14), a network output (15), a customer input (17) and a customer output (16) for data signals, characterized in that the device (12) is designed such that during normal operation, only data received at the customer input (17) is sent onto the network output (15), that the device (12) is further designed such that in case of a failure at the network input (14) or a failure at the hardware of the remote interface device (12), the network output (15) is closed, i.e. no signal at all is sent onto the network output (15), and in case of a failure at the customer input (17), a dedicated auxiliary signal only is sent onto the network output (15). The inventive device allows the use of the full data transfer capacity for customer's data during normal operation, and allows distinction between different types (provider, customer related) of connection failures.

摘要： SONET and SDH signals are framed multiplex signals which are composed of multiplex units according to a respective specified multiplex hierarchy, such that smaller multiplex units are multiplexed in larger multiplex units and that the larger multiplex units are transmitted in frames. Compared to the multiplex hierarchy of SONET, the multiplex hierarchy of SDH has an additional level, namely the VC-4. A method of converting a SONET signal to an SDH signal is disclosed in which the multiplex units of the SONET signals are converted to corresponding multiplex units of the SDH signal, which are multiplexed into multiplex units of the additional hierarchy level. Monitoring functions are applied to both signals in accordance with the SDH multiplex hierarchy. In applying the monitoring functions to the SONET signal, the additional level of the SDH multiplex hierarchy is simulated by setting parameters to be monitored to default values. Thus, there is no need for two separate management systems, since on the SONET side, monitoring can be performed by the SDH management.
摘要翻译： SONET和SDH信号是根据相应指定的多路复用层级由多路复用单元组成的成帧多路复用信号，使得较小的多路复用单元以更大的多路复用单元复用，并且较大的多路复用单元以帧的形式传输。与SONET的复用层次相比，SDH的复用层次结构具有额外的级别，即VC-4。公开了一种将SONET信号转换为SDH信号的方法，其中SONET信号的多路复用单元被转换为SDH信号的相应的多路复用单元，该多路复用单元被复用为附加层次级的多路复用单元。根据SDH复用层次结构，监控功能应用于两个信号。在将监视功能应用于SONET信号时，通过将要监视的参数设置为默认值来模拟SDH Multiplex层次结构的附加级别。因此，不需要两个单独的管理系统，因为在SONET侧，可以通过SDH管理执行监视。

摘要： An 1:n or m:n path protection mechanism is provided. Rather than defining an automatic protection protocol, use is made of the existing tandem connection monitoring function, tandem connection reverse defect indication, and tandem connection trail trace identifier. Upon detection of a failure on the working path segment, the occurrence of this failure is communicated to the far end node by inserting forced RDI into the tandem connection as long as the failure persists. In the case of more than one protected paths, the failed path is identified by means of the unique trail trace identifier received on the protection path. In the case of several protection paths, one network node is defined as slave node which has to follow the switch-over initiated by the master node and choose the same protection path as the master node. Preferably, a combination of two timers enables return from failure condition to normal operation.
摘要翻译：提供1：n或m：n路径保护机制。而不是定义自动保护协议，而是使用现有的串联连接监视功能，串联连接反向缺陷指示和串联连接跟踪跟踪标识符。在检测到工作路径段上的故障时，只要故障仍然存在，将强制RDI插入到串联连接中，将此故障的发生传送到远端节点。在多于一个受保护的路径的情况下，通过在保护路径上接收到的唯一路径跟踪标识符来识别故障路径。在多个保护路径的情况下，一个网络节点被定义为从节点，必须遵循由主节点发起的切换，并选择与主节点相同的保护路径。优选地，两个定时器的组合使得能够从故障状态返回到正常操作。
