DETAILED DESCRIPTION OF INVENTION Such as used in this report, Bluetooth is a short wave radio technology that makes possible data transmission in short distances between any of two electronic machines whose transmission or reception uses such protocol. The term Watchdog timer is a timer circuit that has the objective of a microprocessor after a period of inactivity. DTMF means "Dual Tone Multiple Frequency" and refers to a system of signalization through audio frequency used in telephones and other equipments with capacity in generating such frequency and tones. Interface device between mobile phone line and fixed telephone receivers, object of this invention, operates under two modalities. In Modality 1, interface device operates without having connection to a fixed telephone line and in Modality 2 V\e interface device operates with a connection to a fixed commuted telephone line. MODALITY 1: No connection to a fixed telephone line In this modality, there is no connection to a fixed telephone line (600). Interface device (800) allows interface between a mobile phone line (200) and fixed receivers (300) in typical previous installation, being this installation identical to that one of fixed telephone system without being connected to fixed telephone system. If it is used a mobile phone equipped with short wave radio link such as Bluetooth technology or similar, the connection with the interface (800) happens by approximation between mobile phone (200) and this interface (800) with no necessity of physical contact. The functions operate according said except mobile phone battery that cannot occur with any contact. This convenience is possible thank to operation of radio short wave circuit (1000). Interface device (800) of mobile phone (200) and fixed telephone receivers (300) not connected to a fixed telephone line (600) comprises an interface device with a mobile phone receiver (10) which comprises a mobile phone ring detector (1); a interchangeable module for mobile phone adaptation (4) that allows language adaptation, transmission form, etc, to each mobile phone in the market; a circuit of battery charge of the mobile phone (2); and, optionally, am antenna circuit and a treatment signal for mobile phone antenna (3) whose function is to improve mobile phone receiver performance in a specific place. A microcontroller (20) coordinates the interface device with the mobile phone (10)and the interface device with fixed receivers (80), said microcontroller (20) which includes a central control unit (21 ) which verifies and controls the correct functioning of all stages of the interface device (800); a control for configuration programming (22); a line tone generator (24) and a busy line signal generator (23).

The commands are coded in DTMF audio and may be transmitted by any of the said forms of signals parallelism (electric net anei radio frequency) directly to adaptor module of interface module (800) being DTMF tones sent through either mobile or fixed telephone line and received in automation modules 9120). Automation module (120) is installed between appliances 9400) and electrics* energy switch. In this modality as it was presented in Figure 2 in case of mobile phone ring generator (81) for fixed receivers and when answered the call t is connected the audio in fixed receivers. When picking up the receiver the system connects dialing tone generator in fixed receivers, holds the dialing and the # button at the end. - it avoids dialing to a mobile phone (200) - it connects audio into fixed receivers The system by perceiving all fixeα receivers (300) hanged up, [^' disconnects audio from fixed receivers and informs the end of the call i for mobile phone receiver (200). j MODALITY 2: With commuted fixed line This modality as presented in Figure¹3 the mobile phone (200) and fixed (600) lines are commuted for all fixed telephone net (300) at once from a command originated from one of these fixed receivers. For this modality, interface device (800) is connected to a fixed telephone line being fixed receivers (300) in typical previous installation connected to an external fixed line (600). If it is used a mobile phone equipped with a short wave audio link such as Bluetooth technology or similar the connection with the interface (800) happens by the simple approximation between mobile phone (200) and this interface (800) without the necessity of physical contact. Functions operate according to what was described with exception of mobile phone receiver battery charge that cannot happen without contact. This convenience is possible thank to the short wave radio circuit operation (1000). In this modality the microcontroller (20) coordinates the interfaces with mobile phone (10), with telephone line (90) and with mobile phone (200) and fixed (300) receivers. Central control unity (21 ) of microcontroller (20) is responsible also for generating several audio signals like line tone (24) and busy line tone (23) and for the adaptation work to required configuration programming (22) microcontroller (20) counts also on a guard circuit like "watchdog timer" (50). Interface with mobile phone (10) is the responsible for conditioning data and transmitting them to the mobile phone (200). Interface with telephone line (90) is responsible for DTMF generation (91), for dialing in this fixed line, and for detecting telephone ring (92) occurred in this line. Commutation of fixed telephone line (600) is made by locked deriver (110), commanded by central control unit (21) internal to the microprocessor (20). Interface with fixed receivers (80) is the responsible for generation of electronic ring (81 ) with tension over 90V and for detection of receivers out of the hook (82). The interface with fixed receivers (80) subjects audio signal of line tone and of busy line (83) and also incorporates DTMF tone decoder (84) that recognizes dialing made in fixed receivers (300). Audio commutation in mobile phone is made by locked deriver (30) commanded by central control unit (21) of microcontroller (20). Before arriving to mobile phone (200) and fixed (300) receivers audio signal is conditioned by a dedicated circuit. Automation module (120) allows appliances and illumination control (400), said automation module (120) that receives and decodes signals sent by telephone receivers involved in the process (200 and 300) and acts in appliances feeding (400). Commands are coded in DTMF audio and can be transmitted by any of the said forms of signal parallelism (electrical net and radio frequency) straight to adaptor interface module (800) being DTMF tones sent through mobile or fixed telephone line and received in automation modules (120). Automation module (120) is installed between appliances (400) and electrical energy switch. As it is presented in Figure 4 in case of mobile phone ring (200) it is connected the distinct ring generator for fixed receivers being connected audio in fixed receivers (300) when answered the call. In case of fixed line ring (600) interface device (800) let fixed receivers ring through direct connection and keeps the direct connection when answered the call. Picking the phone up the user will hear the fixed line tone. Being another fixed telephone (300) in conversation through mobile line (200) this call will be heard. To make a phone call through fixed line (600) one has just to pick up the receiver and dial. To make a phone call through mobile phone (200) it is necessary start dialing by # button to inform the interface device (800) that it is wanted the mobile phone line (200) and to end dialing with # button, being dialed number sent to mobile phone (200) connected to interface device.
