摘要： The control device includes a power-saving control unit that intermittently repeats, based on a power saving permission signal transmitted from the master station apparatus, power saving control in which the slave station stops or reduces power supply to a transmitter or a receiver for a predetermined pause duration while maintaining a communication link and a monitoring unit that monitors out of synchronization by comparing a synchronization signal received from the OLT and a time of the ONU. The control device shifts from a registered state to a deregistered state when the monitoring unit detects the out of synchronization. On the other hand, after the pause duration of the power saving control, the control device suppresses the shift to the deregistered state due to the detection of the out of synchronization.

摘要： A dynamic bandwidth assignment system includes a network unit for carrying out cell slot assignment, and a network termination for transmitting cells to the network unit by means of cell slots assigned by the network unit. When the number of consecutive valid cells the network unit receives from the network terminations exceeds a predetermined threshold value, the network unit increases the number of the cell slots to be assigned to the network termination. The system can solve a problem of a conventional system in that it is unavoidable that a cell transfer delay and a bursting tendency of cells are statistically increased.

摘要： A multiplex transmission system of tributary signals multiplexes a plurality of tributary signals after adding to them frame information common to all the tributary signals and identification codes different for the individual tributary signals. This makes it possible to solve a problem of a conventional multiplex system of tributary signals in that the transmission rate is limited because it multiplexes a plurality of tributary signals with adding an SOH (section overhead) to generate an STM-N frame to be transmitted and received, which requires a considerable time.

摘要： A communication apparatus includes a transmitter and a receiver, wherein the transmitter further includes: an interleaver that rearranges positions of bits of an information frame; an FEC encoder that performs an error correction encoding to the information frame whose bit positions have been rearranged; and a selector that inserts FEC parity into predetermined positions of the information frame, to thereby generate a transmission signal, whereas the receiver includes: a selector that extracts an information frame part and an FEC parity part from a reception signal; an interleaver that rearranges positions of the bits of the information frame part using the same rule as that used at that transmitter side; an FEC decoder that corrects an error of bits rearranged based on the error correction parity part; and a de-interleaver that reproduces an information frame by returning positions of error-corrected bits to original bit positions.
