PURPOSE:To transmit and receive a frame synchronization by using the transmitter and the receiver and an asynchronous medium. CONSTITUTION:In a transmitter, a signal generator 11 generates the data signal of a frame synchronization and the frame synchronization. A data packet generator 12 defines the data signal as the data of a data packet and adds a header. A frame marker is set to the header, the head signal of the frame synchronization turns on the marker of an assigned data packet and turns off the markers other than it. An output device 13 has the original clock of a transmission/ reception medium to be connected with a connection part 14, operates by a cycle and outputs a data packet per cycle by the original clock. |
