DIGITAL TELEPHONE SET

PURPOSE:To allow a caller telephone set to recall in one-touch simply by providing the storage means of a caller number, a toll number eliminating means comparing the caller number with its own preset toll number and eliminating the toll number from the caller number when the comparison result is identical and a dial sending means sending a dial signal based on the caller number via the toll number eliminating means. CONSTITUTION:A caller number via a network control means 13 is written in a caller number memory in a RAM 9 by a central processing means 19. A station number eliminating means 17 reads the caller number from the RAM 9 and compares the number with its own toll number. When both toll numbers are coincident, the toll number is eliminated from the caller number and the result is written in the sending number memory of the RAM 9. When the talking by the incoming call is finished and dialing is applied to the talking party from the incoming side, a return dial switch 12 is depressed. A switch detection means 14 detects the said depression and gives a signal to the central processing means 19. A dial sending means 18 receives a sending number stored in the RAM 9 to send a dial signal.
