Patent number: 5757902Abstract: This invention is to provide a telephone exchange capable of operating any one of the juxtaposed and registered extension radiotelephones and wire telephones by only specifying one extension dial number. For this purpose, a wire port physical number is registered in association with a radio port physical number so that two normally separate extension wire telephone (006a, 006b, . . . ) and radiotelephone (008a, 008b, . . . ) can be handled as if they were a single-channel extension phone with a branch switch. Thus, when the user handles two separate radio telephone and wire telephone, the call to the wire telephone can be transferred to the radiotelephone by a simple operation. When the user leaves his desk on which the wire telephone is installed, carrying the radiotelephone with him, it can be carried to a long distance.Type: GrantFiled: December 18, 1995Date of Patent: May 26, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Sadaka Mitsuo
