ABSTRACT:
A cordless telephone system registers a portable unit with a fixed unit by using both wire and wireless links, wherein the portable and fixed units have their own ID numbers. The fixed unit transmits an ID number for the fixed unit, itself, to the portable unit via the wire link, upon receiving registration key data input by a user. Then, the portable unit transmits the received ID number for the fixed unit to the fixed unit together with an ID number for the portable unit, itself, via the wireless link. Upon receiving the ID number for the fixed unit, the fixed unit compares it with an ID number previously stored therein, to register therein the ID number for the portable unit received together with the ID number for the fixed unit, if the previously stored ID number for the fixed unit is identical to the received ID number for the fixed unit.
