Designing a microcontroller-based half-duplex interface device drove by the touch-tone signal

Abstract

The interface device for communicating (IDC) as a bridge for the merger between two different systems based on different protocols and standards can be made of several electronic modules. The two Arduino boards (UNO R3 and MEGA2560 R3) have been constructed as the electronic modules of a gateway become a haft-duplex IDC, and are driven by the touch-tone signal. The research objectives, i.e., assembling some of the hardware for the embodiment of the adapter system, making a program structure, and performing a test of the IDC system. The haft-duplex IDC has been carried out by integrating all components by wiring to form an embedded system. Then, programming the microcontroller modules based on the Arduino software is carried outin six stages. Finally, the simulation test with the provision of conditions is carried out and obtained of six conditions for (i) the circuit of ring detection, (ii) the circuit of voice-operated transmit, (iii) the circuit off/on the hook of the telephone module, (iv) the circuit of tone decoder, (v) dial-up telephone numbers via push buttons and switching IC circuits, and (vi) the circuits of voice recording and storage in the form to playback. The test's success with six conditions has been an indication that the microcontroller-based IDC system is functioning as expected. Completing, the conclusion, and recommendationsrelated to measurement on the various purposes and the real conditions for the half-duplex interface adapter can be implemented.

Observing the Performance of Interface Device for Communicating Based on a Half-Duplex System by Giving a Realistic Condition

“…The ideas and activities of this research are based on previous research which has been published [1,2], namely (i) an electronic device reviewed by diagnosing the embodiment of the module [1] and (ii) designing a microcontroller-based half-duplex interface device driven by the touch-tone signal [2], therefore this research is a follow-up activity in the form of observing the performance of the equipment after the verification tests have been carried out in the previous article [2]. The final result comes from manufacturing or assembling and is an integral part of the new product or product development process are require verification and validation tests [3].…”

“…The radio-based communication system is known as a radio communication system (RCS) or radio-frequency system (RFS) [12][13][14][15], whereas the telephony-based communication system is known as a public switched telephone number (PSTN) or global system for mobile communication (GSM) [16][17][18][19][20]. The connecting device is better known as the IDC and the term interface device for communicating (IDC) is previously known as communication interface adapter (CIA) [1,2]. The stage of the verification test has been published with the product design against its specifications [4].…”
