    • The present invention relates to an optical cross-connect apparatus supporting plural directions, and provides a method of effectively performing an alarm indication by a node supervisory unit of the optical cross-connect apparatus. The node supervisory unit includes an alarm indication information storage unit that manages a management table for each of the plural directions. The management table manages not only received alarm indication information but also “internal WSS input/output port optical fiber connection state”, “WSS optical path setting state on DROP/THROUGH selection side”, “transponder destination location”, and “destination direction”, with respect to each direction. Then, a process flow is added to match received FDI information with the management information stored in the management table for each direction, and to specify an alarm destination.
    • 本发明涉及支持多个方向的光交叉连接装置,并且提供了一种由光交叉连接装置的节点监视单元有效地进行报警指示的方法。 节点管理单元包括管理多个方向中的每一个的管理表的报警指示信息存储单元。 管理表管理不仅接收到报警指示信息,还管理“内部WSS输入/输出端口光纤连接状态”,“DROP / THROUGH选择侧的WSS光路设置状态”,“应答器目的地位置”和“目的地方向” ,相对于每个方向。 然后,添加处理流程以将接收的FDI信息与存储在管理表中的每个方向的管理信息相匹配,并指定报警目的地。
