Abstract

PURPOSE:To save exchange circuits by automatically setting a data transmission mode and by setting a service call mode by a ring-back tone. CONSTITUTION:When dial pulses for data transmission calling or service calling are sent out of a center, a switchboard selects a terminal equipment and sends a call signal to the terminal. On detecting the incoming, the terminal equipment generates a connection answer signal by circuit FGN and then sends it to the center. The center receives this signal and outputs a terminal-equipment selective signal to set the terminal call mode. In data transmission mode, a selective signal frequency is used for the selective signal and the terminal makes discrimination FDT of it to switch a main wire under the switching command of terminal control part CONT, thereby transmitting a text.
