Abstract

PURPOSE:To enable effective data transmission, by storing the data to an exchange station when the reception side is absent and reading out the data at the reception side afterward and displaying it on a display. CONSTITUTION:A telephone set 4 at reception side B is called with a telephone set 5 from an outgoing side A and data transmission is made by using a telephone line 20, then if the reception side B is absent, when bell tone is detected for 30sec or more with a bell tone detector 7, a relay 15 is operated and communication state is made by terminating the input terminal through closing a switch 14, and a data transmitter 9 detects it and illuminates a display device 11. At the same time, a timer 8 is driven and a frequency signal of an oscillator 12 is transmitted for a given time, the transmission side detects it to start data transmission. In this case, in the command given to the part before the data has the address as transmitted part as the data processing during absence, and it is inputted to the registration section with the control of a CPU18 via an exchanger 3 of the exchange station 2 and the data is stored in a memory 19. This registered data is read out with the command at the reception side B and displayed on a display 10.
