ABSTRACT:
In a cordless telephone apparatus including a base unit and a sub unit connected with each other by wireless, the base unit has a memory for storing therein telephone number data which are referred to from the sub unit. When the base unit is busy, the transfer of a calling signal between the sub and base units is not performed. The access from the sub unit to the memory of the base unit is always permitted. The memory includes a callers area in which the telephone numbers of callers of received calls and the reception times of the calls are stored and a directory area in which frequently called telephone numbers and the number of placing calls of the numbers are stored. The telephone numbers in the callers area are retrieved based on the reception times. The telephone numbers in the directory area are retrieved based on the numbers of placing calls. By adding the number of placing calls of the telephone number stored in the callers area to the number of placing calls of the telephone number stored in the directory area, the telephone number retrieval from the directory area functions correctly. Moreover, by using the cordless telephone apparatus as a terminal apparatus of a private telephone system, data stored in a main apparatus of the system are referred to from the sub unit of the terminal apparatus.
