PURPOSE:To transmit a release signal by transmitting a call signal to a subscriber's telephone set at a prescribed time interval so as to remind the releasing even if the incoming service is not released. CONSTITUTION:A processor 9 corresponds to a number inputted in a numeric register 4, i.e., the desired call start time and a subscriber telephone set number by one to one and registers them into a storage device 10. A timer 11 transmits a pulse to the controller 9 at each period. When the pulse is received, the controller 9 retrieves the desired all start time registered in the storage device 10 and when the corresponding designation time or a time elapsed for a prescribed time from the designated time is detected, a telephone number is read and the call signal is transmitted to a telephone set of the user. |
