PURPOSE:To omit the trouble of abbreviated dial number writing by correcting already inputted data with simple button operation. CONSTITUTION:In depressing a write button 29, a control signal section 12 writes 8000H being a head address of a buffer memory 41 assigned to a telephone set T1 to a pointer 43, and a display control data is generated and displayed on a display device 24. Then in dialing '00' being a 2-digit code of an abbreviated number, the control circuit 52 writes 8800H to the pointer 44 and displays it on the display device 24. In dialing '1' being the 1st digit of a subscriber number, the control circuit 52 writes data '1' to the register 42 and writes the content '1' of the register to the address 8000H of the buffer memory represented by the pointer 43. The pointer 43 is incremented by '1' every time the write of the register content is finished. Through similar operation, data '1234567890' to be written correctly is written in the buffer memory 41. |
