摘要： An object of the invention is to provide a diagnosis method for standby systems in an optical ring network having a redundant configuration, which can confirm normal states of standby systems in all optical transmission apparatuses on the network, even during operations of active systems. To this end, in the present diagnosis method for standby systems, when a diagnosis start command is given to an arbitrary optical transmission apparatus on the network, the optical transmission apparatus provides a false signal to a standby system unit to diagnoses an operation state thereof, and transmits the result to the optical transmission apparatus on the downstream side by utilizing overhead information in the active system optical channel. The optical transmission apparatus on the downstream side confirms a normal operation on the upstream side, thereafter, diagnoses the operation state of the standby system by utilizing the false signal, and updates the overhead information of the active system optical channel corresponding to the diagnosis result, to transmit the updated information to the optical transmission apparatus on the further downstream side. According to the overhead information of the active system optical channel, which has made a round of the ring network, normal operations of the standby system units in all optical transmission apparatuses on the network are confirmed, to thereby finish the standby system diagnosis.

摘要： When an edge node whose order is lower than that of a primary switch detects a failure of the primary switch, the edge node requests a secondary switch that the secondary switch serves as a host of the edge node itself. At this time, the secondary switch establishes a connection between the secondary switch and the edge node, generates routing information and label information in a core network which does not comprise the primary switch to give the routing information and the label information to the edge node. The secondary switch performs communication between the edge node and the secondary switch by using the routing information and the label information which are received from the secondary switch.

摘要： A synchronization message detecting unit detects a synchronization message from a line signal received from a line terminating unit. A synchronization message processing unit controls whether or not to select a clock reference received from the line as an active reference according to a quality level represented by the synchronization message. In this case, when an installed state detecting unit has determined that the synchronization message detecting unit has not been installed, the synchronization message processing unit does not select a clock reference corresponding to the synchronization message detected by the synchronization message detecting unit determined as a non-installed unit as the active reference.

摘要： A unit of the invention is installed in each of transmission units that make up a synchronous network. The unit selects from the clock references received an active reference that controls the operation of the corresponding transmission unit, based on the quality levels of clock references presented by synchronization messages received with the clock references. The clock references, each of which is selectable as the active reference, and their selection priorities are entered into a source priority list. By referencing the source priority list, the active reference is selected.

摘要： Operation management of equipment is made efficient by verifying a plurality of operation management manipulations on a plurality of equipment and optimizing a manipulation order before executing the manipulations. A status of equipment in a status table; a content of a manipulation in a manipulation table; a process time of the manipulation in a manipulation time prediction table; and a status required for the manipulation in the manipulation table are memorized on an operation model managing server. When a plurality of manipulations are input for a plurality of equipment by an operation manager via an operation managing server, correctness of the manipulations is verified and a manipulation order is decided on an operation verifying server based on the various types of memorized information. Also, a manipulation end time of each manipulation is notified to the operation manager via the operation managing server.
