Data from individual lines are only processed by logical circuits. Data received by any of the lines are sent to all the other lines. Individual lines have no buffer for data receipt.
When data arrive almost simultaneously to two lines, the system receives the data whose beginning was first registered. The other lines switch to "Transmission" and start to transmit the data. After the data receipt has been completed the system waits for a configured period of time (a so called "Switching Delay"). After this period has elapsed, all the lines switch to "Receipt" and wait for data to come.
