MESSAGE PACKET TRANSMITTER

摘要

PURPOSE: To provide the message packet transmitter that sends a packet of an electronic data signal to a communication network without interruption. CONSTITUTION: A first-in first-out electronic memory 10 has a transmission state where an electronic data signal stored in the memory is outputted and an idle state where no electronic data signal is outputted. A message packet transmission state identification circuit 16 generates a packet transmission state signal after the electronic memory 10 outputs the first electronic data signal. A non-packet transmission state signal is generated after the electronic memory 10 outputs the final electronic data signal. A state controller 18 keeps the electronic memory 10 to be the transmission state when the electronic memory 10 stores at least part of message packets when the state controller 18 receives a packet sending signal and when the state controller 18 receives an interrupt hold signal.
