Ring-type lan

Abstract

Abstract PURPOSE:To transmit a musical sound control data and an audio data by using one LAN by encoding the musical sound control data and the audio data to symbols by the same encoding method, generating a frame by using the respective symbols, and transmitting the frame. CONSTITUTION:Based on the output timing of a transmission control signal TCTL to be outputted from a transmission data input part 9 of a packet exchange type LAN connection part 4, a music control data DT such as a key-on signal or the like is outputted from a music control data processing part 21 and inputted to the transmission data input part 9 of the packet exchange type LAN connection part 4. Next, in the packet exchange type LAN connection part 4, a frame/token bit train F/TBA is generated based on the music control data DT and this frame/token bit train F/TBA is outputted synchronously with an output clock CKT provided in the packet exchange type LAN connection part 4, and inputted to an encoding part 13 of a line exchange type LAN connection part 15.
