Abstract

PURPOSE:To increase the conventionality of a delayed-on-line use data terminal device using a telephone line, by the incoming control through the automatic selection of a data communication mode and an audio communication mode. CONSTITUTION:In response to the reception 1 of a dial signal, a device automatically closing the hook switch 3 of a signal path is provided, and a timer circuit 7 generating a bell ringing signal after a prescribed time through the start at the automatic closing of the hook switch 3, is provided. Further, depending on the presence/absencr of the reception 9 of an ENQ signal ahead the data signal within a set time of this timer circuit 7, a gate circuit 8 controlling the bell ringing signal from the timer circuit 7 is provided, and if the reception of the ENQ signal is not made within the set time of the timer circuit 7, the output of the gate circuit 8 rings a bell 12 to instruct the request of audio communication.
