Abstract
In today world, the importance of the communication technology can’t be denied. A large number of improvements have be designed and developed in the field of communication and information technology. The objective of this project is to use the communications network of the public switched telephone network to access and control the internal intercom system. This is a simple but effective internal intercom system for homes, offices, schools, colleges or banks. The system is designed for up to seven sets, each of which generates a pulse code when dialing a number or type in. This project uses a microcontroller to provide different functions. The circuit provides a simple illustration of a telephone intercom system that has bidirectional communication with the characteristics of LM386 amplifier. Our system consists of a central control unit which can access all remote nodes and can send as well as retrieve user data by using DTMF decoding.
Keyword:
Communication Technology, Circuit, amplifier, Mobile Station, Public switched telephone network (PSTN), Pulse code.
