摘要： A method for restoration from a fault in a communication network formed by interconnecting a plurality of nodes including at least one set of node equipment each including a line terminal equipment and an optical cross-connect equipment, via a plurality of transmission lines using optical fibers. According to this method for restoration from a fault, if a line terminal equipment of at least one set of node equipment has detected a fault in an optical fiber under communication, it gives a command functioning as trigger for optical fiber change-over to an optical cross-connect equipment included in the node equipment. Upon receiving this command functioning as the trigger, the optical cross-connect equipment exchanges change-over control information indicating optical switch setting situation between it and an optical cross-connect equipment included in another node equipment, and forms a restoration route.

摘要： Input/output fibers for the optical cross-connect system are classified into working fibers and protecting fibers. In a normal time (a state in which there occurs no failure), there turns out to be a one-to-one correspondence between a line terminal and a working fiber. Namely, connection property required for the switch matrix in the optical cross-connect system is not necessarily strictly non-blocking connections among all of the fibers. The connection property is a one-to-one connection relationship with the working fibers, and is a predetermined connection relationship with the protecting fibers at the time of a failure occurrence. Utilization thereof makes it possible to extremely downsize scale of the switch.

摘要翻译： 光交叉连接系统的输入/输出光纤分为工作光纤和保护光纤。 在正常时间（没有发生故障的状态）中，线路终端和工作光纤之间的一一对应关系成立。 即，光交叉连接系统中的开关矩阵所需的连接特性不一定是所有光纤之间严格的非阻塞连接。 连接属性是与工作纤维的一对一连接关系，并且是在发生故障时与保护纤维的预定连接关系。 其利用使得可以极大地减小开关的尺寸。
