Abstract

The central aim of this work is to validate the concepts and ideas for the development and implementation of an interphone system for condominium environments using the electric cabling as a means of propagating the voice signals. In this way the need for the installation of a specific new medium for communication between the terminals is dispensed with, as is the need for a central routing unit. The basic objective is to make available a solution to meet the needs of users who do not have an efficient means of communication amongst themselves, or which represents an important safety item. Or to cater for those who live in environments where the installation of currently available systems is difficult or costly. Technically each interphone will be an independent terminal, capable of entering or leaving the network environment without impairing it. To guarantee secrecy and reliability in the communication or in the establishment of the link, some sort of spectral diffuser will be used, adding to this product a modern technology, which will allow for an expansion of functions.We will also make available a low cost, flexible and secure alternative means of closed network communication.
