WIRED TELEPHONE COMMUNICATION SYSTEM USING WIRELESS COMMUNICATION MODULE

摘要

PURPOSE: A wired telephone communication system using a wireless communication module is provided to allow residents to freely communicate in the outside and inside by appropriately switching and connecting a number of wire telephones and wireless communication modules. CONSTITUTION: A number of wireless communication modules(10a, 10b, ...,10n) receive telephone signals from the outside or send the telephone signals to a wireless telephone communication network in the outside. Any one of the wireless communication modules(10a, 10b, ...,10n) is allocated to a key number. A number of wire telephones(1a, 1b, ...,1n) are connected to a wire telephone connection part(30). A switching and connecting part(23) switches and connects the many of wire telephones and the many wireless communication modules, and establishes a communication channel between them. A guiding part(24) guides information necessary for a telephone communication. A controlling part(21) is connected to the many wireless communication modules(10a, 10b, ...,10n), the switching and connecting part(23) and the guiding part(24), and also connected to the many wire telephones(1a, 1b, ...,1n) via the connecting part(30) to control the telephone signal between them.
