<p><P>PROBLEM TO BE SOLVED: To provide a transmission unit, data processing unit, path selecting unit, and control unit, capable of settling complication of an interface between a line processing part and a line switch part. <P>SOLUTION: A transmission/reception control part 7 transmits signal S1T to a transmission part 1S if simultaneously receiving signal S1F and signal S2F. The signal S1T makes the transmission part 1S stand by for a specified period to transmit data. The transmission part 1S holds outputting of data to a data bus 6 while the signal S1T is inputted. Thus, transmission of data to the data bus 6 is performed from a transmission part 2S and the transmission part 1S in this order, preventing duplicate transmission of data to the data bus 6. The interface between a line processing part 4 and a line switch part 5 is realized by a pair of data buses as the control operation is performed by the transmission/reception control part 7. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
