Abstract

La présente invention concerne un frontal analogique renforcé permettant de connecter des entre eux un dispositif de communication par réseau à un réseau à base de deux conducteurs qui peut fonctionner dans un environnement de type train ou dans un autre environnement hostile. Ce frontal possède un circuit de couplage possédant un premier et un second canal de couplage fournissant une isolation, une correspondance d'impédance et un transfert d'énergie entre un circuit filtre de mode commun connectable au réseau à base de deux conducteurs et, un amplificateur et un atténuateur respectivement connectables à la sortie et à l'entrée du dispositif de communication par réseau. Ce frontal possède un circuit d'alimentation électrique destiné à alimenter en puissance de fonctionnement des composants électroniques de ce frontal analogique.
