摘要： A plug-in card for an optical transmission apparatus includes a J1generating unit. The J1 generating unit sends information on on-use side J1 data to a plug-in card at a spare side in a redundant structure when the plug-in card operates as an on-use side plug-in card. The J1 generating unit receives information on on-use side J1 data from a plug-in card at the on-use side when the plug-in card operates as a spare side plug-in card. Based on the information, the J1 generating unit matches spare side J1 data to the on-use side J1 data. The plug-in card also includes a B3 byte calculating unit that operates in a similar way as the J1 generating unit does in processing B3 byte data.

摘要： A transmission device in which a bus of a central processing unit is used to synchronize timing signals between units, thereby restraining enlargement in scale of wiring. A reference signal generator generates a reference signal. A reference signal receiver is mounted on a unit set as an active or standby unit and receives the reference signal. A timing signal generator divides the frequency of the received reference signal by means of a frequency divider/counter to generate a timing signal. A count holder holds the count value of the frequency divider/counter. The bus connects the units and the central processing unit. A count receiver receives, via the bus, the count value from the count holder of the active unit. A count updater updates the count value of the frequency divider/counter to the count value received by the count receiver.

摘要： The invention relates to a subordinate apparatus and a superordinate apparatus. The object thereof is to surely detecting an erroneous connection in a wiring between these apparatus and identifying an erroneously connected cable. A subordinate apparatus has an identifier acquiring section acquiring an identifier that is granted by a superordinate apparatus via a communication link that is formed via a first cable. When granted a new identifier via the communication link, the identifier acquiring section makes a first judgment as to whether there is an identifier granted prior to the new identifier. The identifier acquiring section nullifies the new identifier if there is an identifier granted prior to the new identifier.

摘要： An optical transmission system transmits an optical signal of multi-level modulation. In a transmitter module, a data string in a specified frame is rearranged into a plurality of logical lanes. A lane ID, which specifies in what logical lane out of the plurality of logical lanes a start of the data string is arranged, is assigned to a non-scrambled area in an overhead portion of the frame. The lane ID corresponding to one of the plurality of logical lanes is different from the lane IDs corresponding to the other remaining logical lanes. The optical signal is generated using the data string rearranged into the plurality of logical lanes. In a receiver, the lane ID is detected according to a majority method. The inversion of bits and the swapping of lanes are detected using the lane ID and compensated.
