A guarantee information adding section adds guarantee information for guaranteeing the continuity of the divided signals to each of the divided signals to generate transmission signals. A signal sending section sends the transmission signals via a transmission line in the transmission interface format. A signal receiving section receives the transmission signals. A signal restoring section restores the multiplexed signal by constructing the divided signals on the basis of the guarantee information.

摘要： A network synchronization controller and method for effectively preventing a timing loop from happening in a synchronous network. A clock status message controller, disposed in each network element on the network, produces and sends clock status messages which are each composed of clock quality data and synchronization control data. The clock quality data indicates the quality level of a clock signal that each network element supplies to its neighboring network elements. The synchronization control data contains information to be used to make the network synchronized with a single reference timing source. A clock selector chooses one of the clock signals received from other network elements, based on the clock status messages received along with the clock signals.

摘要： When line trouble occurs in an optical network, the restoration time can be reduced. A transponder 21 includes an active line and a standby line 43, and a transponder 22 includes an active line 42 and a standby line 44. The standby line 44 of the transponder 22 is accommodated in the same optical line as the active line 41 of the transponder 21. Upon detection of line trouble, the receiving transponder 24 acquires a VDC setting value for the active line 41, and sets the VDC setting value for the standby line 44 on the basis of the acquired VDC setting value.
