<p>PURPOSE:Tc relax the collision occurrence time on a network and to improve the utilizing efficiency by accessing each terminal equipment and storing a transmission data from each terminal equipment tentatively if the transmission data from each terminal equipment collide with each other on the network. CONSTITUTION:A terminal equipment control circuit 4 generating an access signal sequentially to plural terminal equipments 1-3 and receiving a transmission data being an answer signal from the terminal equipments 1-3, and a memory circuit 5 storing the transmission data from the terminal equipments 1-3 received by the terminal control circuit 4 sequentially and sending the transmission data from the terminal equipments 1-3 to be stored depending on the presence or absence from an external busy signal are provided to the system. That is, the presence or absence of the transmission data from the terminal equipment control circuit 4 to the terminal equipments 1-3 is confirmed, the transmission data from the terminal equipment, if any, is received and stored tentatively in the memory circuit 6. After the presence of an idle terminal equipment on the network is confirmed by the busy signal, the stored transmission data is sent. Thus, the collision of data is relaxed and the utilizing efficiency is improved.</p> |
