PROBLEM TO BE SOLVED: To make channels between synchronization system terminal equipments efficient in the ATM network system. SOLUTION: An ATM cell received from an ATM network 70 is given to a cell assembly/disassembly function CLAD 4RN corresponding to header information by a cell switch 60 and converted into synchronization system terminal data and stored in each buffer BUFFN2N. A read frequency of which BUFFN2 N is to be corrected is checked through the calculation of priority and corrected by using an adaptive clock recovery method based on a capacity and an accumulated object value of each BUFFN2N and on an accumulated value of each BUFFN2N set to a control section CONT01 at setting of a channel. The read frequency of each BUFFN2N is corrected on the basis of a corrected read frequency. A data read gate RD3N is operated by the corrected read frequency of each BUFFN2N and data are shaped into synchronization system terminal data by a multiplexer/demultiplexer section MUX/DMUX 50 and the resulting data are sent to a synchronization synchronizing signal terminal equipment 80. |
