Abstract

PROBLEM TO BE SOLVED: To call an externally mounted telephone set when an incoming call reaches a line by providing an incoming call reception function and an externally mounted telephone set call signal function to the line selector. SOLUTION: When the line selector 20 receives a selection signal of a portable telephone set 2 or a wired public line 3 from an externally mounted telephone set 1, the selector 20 directly connect the telephone set 1 to the portable telephone set 2 or the line 3 so as to build up a public channel by a radio channel or a wired channel respectively. Furthermore, when an incoming call comes from the wired public line 3 and a bell signal recognition section 7 recognizes an incoming call bell signal, a control signal 11 allows a line changeover section 12 to connect the line 3 and the externally mounted telephone set 1 directly. When an incoming call comes from the radio public line to the portable telephone set 2, the control section 11 recognizes the incoming call signal and allows a bell signal transmission section 10 to transmit a bell signal, and when the externally mounted telephone set 1 is hooked off, the control section 11 allows the line changeover section 12 to directly connect the portable telephone set 2 to the telephone set 1. Moreover, because the method for detecting an incoming call differs, the user can recognize an incoming call to other line even when one line is busy.
