Abstract

PURPOSE:To make effective use for the line and center, by disconnecting the line with the data center, through the automatic delivery of communication end signal at ON-hook. CONSTITUTION:When the data center is called out with the dial 102 via the lines 1, 1' by hooking on the handset 101 of the communication line 10, the signal A is received a detected with the response of center, and the contact is selected to the position b with the relay 15 operated through the control circuit 14. After a series of data is transmitted from the signal transmission circuit 11 with the operation of the keyboard 16, the signal B is transmitted with the operation of the data processing request key, and next the contact is selected to the position a with the restoration of the relay 15, the audio answer of the processing result and the signal A can be obtained with the handset 101, the contact is again selected to the position b, further the contact 3 is closed with the ON-hook, and the communication end signal B is delivered for a given time from the circuit 13.
