PURPOSE:To obtain surely redialing functions, by storing data of a remote number obtained on the basis of dial operation just after off-hook to the next time surely. CONSTITUTION:In hooking up a handset and an abbreviation dial function switch circuit 15 is operated, a signal is inputted to a processing section 20, which stores a number data corresponding to the data stored in an RAM3 into an RAM1 temporarily. The number data in the RAM1 is written in the RAM2 in order and transmitted to a telephone set 11 via a data bus 28. When the transmission is all finished, the mode is the input waiting consisting of a key pad 14 and a function switch circuit 15. When the number data is inputted from the key pad 14, if the number data of the remote station is >=12 digits, the data writing to the RAM2 is inhibited until the mode is transferred to the on-hook. |
