PURPOSE:To improve the line efficiency by registering the on-line registration of its own from each terminal equipment to other terminal equipment at each prescribed time interval and informing a link request to a network. CONSTITUTION:Terminal equipments A, B, C, D, M and N register the registration text of their own in the order of terminal equipments. A '0' at the end of each registration text represents a monopoly statement, the other terminal equipments are in reception state and '1' at the end indicate a token flag. The registration text is sent in a line loop L at each prescribed time. A normal terminal equipment sets a registration bit 1 at each time and when the address is preceding to its own address and the registration test does not come within a prescribed time, the registration is cancelled. After the registration is finished, when a data transmission request comes from a connected computer or terminal T, the data is sent to the opposite terminal equipment synchronously with its own sequence.
