摘要： A relay unit capable of avoiding the occurrence of simultaneous switching whatever data is received and thereby preventing malfunction of the device due to impulse noise, and a memory product having stored therein a computer program are provided. The relay unit includes a latch unit that temporarily stores converted parallel data; a determining unit that compares received data with subsequent data to be received subsequently and thereby determines whether to invert bits of data; and an inverting unit that invert bits of converted serial data. When the determining unit determines that bit-inverted parallel data is received as subsequent data, the determining unit transmits to the latch unit a signal instructing to prohibit from storing temporarily the received subsequent data and transmits to the inverting unit a signal instructing to invert bits of data.
摘要翻译：一种中继单元，其能够避免任何数据被接收的同时切换的发生，从而防止由于脉冲噪声引起的设备故障，并且提供其中存储有计算机程序的存储器产品。中继单元包括：临时存储转换的并行数据的锁存单元; 确定单元，将接收到的数据与随后要接收的随后数据进行比较，从而确定是否反转数据位; 以及反转单元，其反转转换的串行数据的比特。当确定单元确定接收到位反转的并行数据作为后续数据时，确定单元向锁存单元发送指示禁止临时存储所接收的后续数据的信号，并向反转单元发送指示反转的位的信号数据。

摘要： An uninterruptible transfer can be realized during a line failure in a transmission system performing a packet transmission between transmitting apparatuses connected via a plurality of lines. In a method for realizing the uninterruptible transfer, test packets including information of the number of packets received from the transmitting apparatus of a destination are periodically sent to the transmitting apparatus of a source. The transmitting apparatus of the source compares the received information of the number of packets included in the received test packets with the number of packets sent out to the transmitting apparatus of the destination via one line. When the comparison shows a disagreement between the number of the received packets and the number of the sent-out packets, packets corresponding to the disagreement are resent to the transmitting apparatus of the destination via another line. The packets, before being sent out to the transmitting apparatus of the destination, are stored in a buffer memory. When the comparison shows an agreement between the number of the received packets and the number of the sent-out packets, packets, which are stored in the buffer memory, corresponding to the agreement are released from the buffer memory.
摘要翻译：在通过多条线路连接的发送装置之间执行分组传输的传输系统的线路故障期间，可以实现不间断传送。在实现不间断传送的方法中，周期性地向源的发送装置发送包括从目的地的发送装置接收的分组数量的信息的测试分组。源的发送装置将接收到的测试分组中包含的分组数量的接收信息与经由一行发送到目的地的发送装置的分组的数量进行比较。当比较表示接收到的分组数与发送分组的数量之间存在分歧时，对应于不一致的分组通过另一行重新发送到目的地的发送装置。在发送到目的地的发送装置之前，分组被存储在缓冲存储器中。当比较表示接收到的数据包的数量和发送数据包的数量之间的一致性时，从缓冲存储器释放对应于协议的存储在缓冲存储器中的数据包。

摘要： A frame transmission device which does not require a separate supervisory line and enables supervisory frames to efficiently enter subscriber traffic for transmission without securing a fixed bandwidth. A supervisory token computing section gives supervisory frames supervisory tokens as permission to transmit within a minimum bandwidth. Subscriber token computing sections give subscriber frames subscriber tokens as permission to transmit within respective set transmission bandwidths. A best-effort token computing section gives the frames best-effort tokens as permission to transmit by using an extra bandwidth. The supervisory or subscriber tokens are given to read frames from a supervisory queue or subscriber queues, and if a frame queue length is smaller than or equal to the best-effort tokens remains in the queue, a queue read control section reads and outputs the remaining frames from the queue by using the extra bandwidth of best-effort tokens.
