摘要： A transmission apparatus includes an active programmable device; a standby programmable device upgrading the version; an external memory part that includes a table memory and a main signal memory and that is shared between the two programmable devices; and a switching part that selects either of the main signals processed by the two programmable devices to transmit the selected main signal to an output path. The active programmable device is capable of processing the main signals in parallel with the standby programmable device and receives a notification of completion of the version upgrade from the standby programmable device to issue an instruction to start switching to the standby programmable device. The standby programmable device uses the table memory and the main signal memory updated by the active programmable device to process the main signals in response to the instruction to start the switching.

摘要： An apparatus for frame transmission includes a dummy data inserting unit that inserts dummy data, at timing of an interval in which a received frame input intermittently is not detected, in a sequence of processing processes of scrambling processing of user data cut out from the received frame, reading-out of the data after the scrambling processing with a parity appended thereto from a memory and parity checking thereof, and descrambling processing of the data after the parity checking, and an error determining unit that determines whether an error is occurring in the sequence of the processing processes, based on the dummy data obtained by the descrambling processing of the dummy data inserted in the sequence of the processing processes by the dummy data inserting unit.

摘要： A data communication apparatus stores each data received via a network and transfers each data in accordance with destination addresses of each data. The data communication apparatus includes a stop-control information generator, which upon updating of circuit configuration information of a programmable logic circuit provided in the data communication apparatus is performed, generates stop-control information stopping data transmitted from an external data communication apparatus from entering the programmable logic circuit.
