摘要： A method of mapping a virtual container multiplexed with a pointer indicating a first bit position in a transmission frame onto an asynchronous transfer mode cell and transmitting the virtual container thus converted. The method includes the steps of deriving a first bit position of the virtual container in the transmission frame from the value of the pointer of the virtual container, mapping the virtual container onto information fields of cells, deriving a first bit position of the virtual container within a cell information field of the asynchronous transfer mode cell from the first bit position information in the frame, and writing the first bit position information within the cell information field and information contained in the pointer into a field which has a fixed phase relationship with respect to a cell header and transmitting the cells.

In system switching, control information for switching between the primary system and the standby system is prepared. When a cell is inputted to the communication apparatus, the prepared control information is appended in a header portion of the cell. The cell with control information appended thereto is transmitted to the duplex system including the primary system and the standby system. On the basis of the control information, cell transfer of each system is controlled.

摘要： A client signal having a constant bit rate is segmented every a bytes to create code information blocks. The bit rate of the client signal is increased such that the client signal has the code information block and an empty area comprised of b bytes, and the ratio c/a is equal to or higher than 110% to create a code block 3 comprised of c bytes. The code information block in the code block is encoded such that an error correcting code is included therein to have an encoding gain of 6 dB or higher for a bit error ratio of 10−12. Associated check bits are placed in the empty area to eventually generate a super FEC signal.

摘要： An optical one-to-one protection switching apparatus exchanges signals between a transmit node and a receive node. If a fault is detected in the first transmission line (down-stream), a controller in the node controls a drive circuit so as to shut off a gate. Then, the controller in the transmit node upon receiving a switching request from the receive node, controls the drive circuit so as to shut off the gate. Thereby, the optical switch is switched. The transmitter of the client terminal is thus connected to the second transmission line (down-stream). Upon receiving the switching request from the transmit node, the optical switch in the receive node is switched. Thereby the receiver in the client terminal is connected to the second transmission line (down-stream).
