摘要： A node device in an optical transport ring network including plural node devices connected in a ring form using plural optical transmission paths so that optical transport frames of a working line and a protection line are transmitted using the plural optical transmission paths, includes a control information transmitter, when a failure occurs in the optical transmission paths, transmitting the optical transport frame to an opposing node device as a transmission destination node in the optical transmission paths, the optical transport frame including switching control information; and a switcher receiving the optical transport frame including switching control information, the optical transport frame being transmitted to the node device as the transmission destination node, forming a loop back to fold a transmission path between the plural optical transmission paths, and switching the optical transmission path from the work line to the protection line.

摘要： A read address from a memory and a write address to the memory are transmitted from a VT pointer circuit on an active side to a VT pointer circuit on a standby side in order to eliminate a difference between pointer values of the VT pointer circuits on the active and the standby sides, which is caused by a difference between the phases of the read address from the memory and the write address to the memory of the VT pointer circuits on the active and the standby sides, and the read and the write addresses on the standby side are overwritten with the transmitted address values. As a result, the address values can be made to match both on the active and the standby sides, and also the pointer values can be made to match.
摘要翻译：从存储器的读地址和存储器的写地址从有源侧的VT指针电路发送到备用侧的VT指针电路，以消除活动的VT指针电路的指针值之间的差异以及由存储器的读取地址的相位与主动和待机侧的VT指针电路的写入地址到存储器之间的差异以及在写入地址上的读取和写入地址引起的待机侧待机侧被发送的地址值覆盖。因此，可以使地址值在活动和待机侧都匹配，并且可以使指针值匹配。
