摘要： PURPOSE:To prevent the complication of control operations for a synchronous data processor included in a communication network which transmits the data containing the synchronous and asynchronous data. CONSTITUTION:The node devices 2-4 are connected to a transmission line 1 where a synchronous data processor is contained in a synchronous data circuit and the data containing both synchronous and asynchronous data are transmitted. A synchronous data processing part 7 excludes the control data out of a transmission frame by means of an elastic memory to transmit the transmission frame sent from the line 1 to the synchronous data circuit. Then the part 7 converters only the information part of a cell into the formats which are closed forward and continuous. Thus the synchronous data processor can easily specify the positions of cells and channels and can facilitate its control operations. Furthermore a warning signal is produced before the write/read phase difference affects the elastic memory. So that the jitters and the phase difference caused between the node independent synchronous clocks and the network synchronous clocks can be absorbed.
