摘要： A subnetwork connection system is provided that includes line modules configures to receive traffic signals over bridged, individual corresponding channels. The line modules are grouped into sets at a lower protection layer, while the sets of line modules are organized into working legs and protection legs at an upper protection layer. The line modules are activated and deactivated based on different upper and lower protection schemes associated with the upper and lower protection layers. The subconnection system further includes state maps associated with each of the line modules. The state maps store state data that activates and deactivates the line modules. The state maps are updates in accordance with the lower protection scheme to permit intra-leg switching between the line modules in one of the working and protection legs. The state map is also updated in accordance with the upper protection scheme to perform inter-leg switching between a first line module in one of the working and protection legs and a second line module in the other of the working and protection legs. The subnetwork connection system also includes a network control module interconnected with the line modules. The control module performs inter-leg switching by updating the state data in the state maps for corresponding line modules in associated working and protection legs.
摘要翻译：提供了一种子网连接系统，其包括线路模块配置以通过桥接的各个对应的信道接收业务信号。线路模块在较低保护层处被分组成集合，而线组件组被组织成上保护层的工作腿和保护腿。基于与上保护层和下保护层相关联的不同的上和下保护方案，线路模块被激活和去激活。子连接系统还包括与每个线路模块相关联的状态图。状态映射存储状态数据，激活和停用线路模块。状态图是根据较低保护方案的更新，以允许在工作和保护腿之一之间的线路模块之间的腿内切换。还根据上保护方案更新状态图，以在工作和保护腿中的一个中的第一线路模块和另一个工作和保护腿中的第二线路模块之间进行腿间切换。子网连接系统还包括与线路模块互连的网络控制模块。控制模块通过在相关联的工作和保护腿中的相应线路模块的状态图中更新状态数据来执行腿间切换。
