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, etc.) and radiotelephone (008a, 008b, etc.) can be handled as if they were a single-channel extension phone with a branch switch.

本发明是为了提供这样一种电话交换机：只需指定一个分机拨号号码，便可使用并置的和被注册的分机无线电话和分机有线电话中的任何一个，因此，有线端口的物理号码和无线端口的物理号码被联合注册，这样，两个在常规上是分离的分机有线电话（006a，006b……）和分机无线电话（008a，008b……）可以象具有一个分支切换a branch switch）的单通道分机电话一样来被处理。

The speaker generates sound responsive to the received radiotelephone communications, the microphone generates electrical signals for the transmitted radiotelephone communications responsive to outside sound, and the patch antenna includes a conductive layer coupled to at least one of the processor and the transceiver.
