PURPOSE:To attain the transmission of a dial number data succeeding to a stored dial number data with a simple operation by providing a processing means incrementing or decrementing a subscriber telephone number data read from a storage device by 1. CONSTITUTION:An analysis section 21 analyzes an output of a decoder 6 and outputs a control signal representing an input by one key among subscriber button keys 2 to a processing section 22. Then, a reading means 23 reads a corresponding dial number data from an RAM9 and stores it in the register of the processing section 22. Further, the means 23 transmits the dial number data to a signal line 25. If a called party by this operation is busy, the operator depresses an increment/decrement indicating key 13. Thus, the processing section 22 adds 1 to the dial number data in a register to form a dial number data, which is transmitted to a signal line 25. |
