ABSTRACT:
A radio communication apparatus includes a base unit connected to wired lines and a plurality of radio telephone sets connected to the base unit via a radio link, and can inform an operator using each individual radio telephone set of service states of the wired lines without a special operation. Wired-line information indicative of the service states of the wired lines is transmitted with such wired-line information contained in a control signal which is transmitted from the base unit to the radio telephone sets when the base unit is to establish a radio link with the radio telephone sets or at the time of the termination of establishing the radio link. The radio telephone sets receives information indicative of the service states of the wired lines from the base unit, and displays the service states of the wired lines on a display device on the basis of such information.
