Abstract

CIRCUITO INTEGRADO PARA SER UTILIZADO EN UN APARATO DE ABONADO TELEFONICO. CONSTA DE UNA PLURALIDAD DE UNIDADES DE CIRCUITO, CADA UNA ADAPTADA PARA SER UTILIZADA EN UNA O MAS ENTRE LOS DIFERENTES MODOS DE TRAJO DEL CIRCUITO, ESTANDO CADA UNA DE DICHAS UNIDADES DE CIRCUITO CONECTADAS AL CIRCUITO INTEGRADO DE LA FUENTE DE ALIMENTACION, CUANDO ES UTILIZADO, PARA LO CUAL SE LE ADJUDICA UN CONMUTADOR ELECTRONICO DE FORMA QUE CUANDO DICHOS CONMUTADORES SON ACTIVADOS, SUS UNIDADES DE CIRCUITOS SON DESCONECTADAS; Y DE UNA UNIDAD DE CONTROL CONECTADA A LOS CONMUTADORES ELECTRONICOS, LA CUAL RESPONDE A LAS SEÑALES INDICATIVAS DEL MODO DE OPERACION DE LOS CIRCUITOS PARA VALIDAR LOS CONMUTADORES ELECTRONICOS, DE FORMA QUE LA UNIDAD DE CIRCUITO CORRESPONDIENTE SE DESCONECTE.
