<P>PROBLEM TO BE SOLVED: To provide a communication terminal conversion device which requires no phase adjustment regardless of models, and which more surely captures data. <P>SOLUTION: A communication terminal conversion device is provided with a delay circuit 16 for delaying reception data 7 transmitted from a terminal side and for outputting reception delay data 23, a conversion circuit 4 for converting the reception delay data 23 captured by a reception timing clock 18 to be transmitted to a digital line side 2, and a phase detection circuit 13 for detecting a relative phase 22 between a change point of the reception timing clock 18 and a change point of the reception data 7. The delay circuit 16 delays the reception data 7, based on the relative phase 22. Although the reception data 7 are delayed, the clock will not be delayed. Therefore, the delay circuit is dimple. Only by delaying data by a single clock, a reliable data capture is made possible. Thus, a phase adjustment corresponding to models is not required, the data are captured reliably, only reception data are signals which receive delay, and the delay circuit is simple. <P>COPYRIGHT: (C)2003,JPO |
