Abstract
Este comprende, entre otras cosas, un circuito de cruce (SLIC2) con funciones verificadoras integradas relacionadas con la línea de usuario, uncircuito verificador (TS) realizado, en el más simple de los casos, por una resistenciaohmica, y un relé conmutador (MR) que presenta dos contactosconmutadores (u1, u2), por medio del cual en una posicion de contacto, los conductores (a, b) de la línea de usuario están conectados con el circuito decruce y, en la otra posicion decontacto , se separa la línea de usuario y se conecta el circuito verificador al circuito de cruce.
