Abstract: A method, a network, and a node each implement the transmission of Automatic Protection Switching (APS) switching coordination bytes across an OTN network. A working signal and a protection signal are received, one of which is designated as an active signal. The active signal is encapsulated in an Optical channel Data Unit (ODU) signal. APS switching coordination bytes from the working and protection signals are placed in an overhead segment of the ODU signal. The ODU signal is transmitted into and received from an Optical Transport Network (OTN) network. The working and protection signals are recreated based on the active signal encapsulated in the ODU signal and the APS switching coordination bytes in the overhead segment. The recreated working and protection signals are transmitted. In this manner, a single ODU signal may be used to transmit both the working and protection signals.

Abstract: A communications network determines for itself its own network topology, that is, the identity and interconnection of nodes comprising the network. The network comprises a plurality of nodes each having at least one port. The ports are interconnected in accordance with the network topology in which communication traffic is conveyed over the network via the interconnected ports. Each port is arranged to transmit first information within the communication traffic including the identity of the port (Section trace identity) from which the communication traffic originates. Second information is transmitted between nodes identifying which first information identity relates to which node and which port. A processor is operative for determining for each node from the first and second information the identity of adjacent nodes and the identity of the ports to which its ports are connected.

Abstract: A request requesting a real time clock (RTC) value in a communications network is sent from a network element to a management system via a data communications network. The time taken from the sending of the request to the receipt of the RTC value is compared with a predetermined maximum and, if less than or equal to the maximum, the network element RTC is updated. If above the maximum, the RTC value is discarded, and a fresh request is sent. The received acceptable RTC value may be corrected by subtracting either the minimum transmission time or half the actual transmission time.

Abstract: A transmission unit which transports digital signals between different network systems, effectively converting the signals to resolve their differences in the specifications. A first signal interface transmits and receives first network signals. A second signal interface transmits and receives second network signals. A downward converter produces lower-level signals by converting received first and second network signals to a lower hierarchical level at which the first and second network systems are compatible with each other in terms of logical signal structure. An upward converter produces a higher-level signal by converting each given lower-level signal to an upper hierarchical level which complies with the first or second network system. A loopback unit provides loopback paths to route the lower-level signals from the downward converter to the upward converter, so that the first and second network signal will be converted in both directions.

Abstract: A data transfer system allowing transmission of control information independently of communication protocols is disclosed. A data transmission equipment working in a predetermined communication protocol receives a transmission signal including control information from upstream. The control information is forwarded to a transmitting section without controlling the control information according to the predetermined communication protocol. The transmitting section transmits a transmission signal including the control information to downstream.

Abstract: 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.

Abstract translation: 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，就将该故障的发生通过插入强制的RDI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。
