Abstract

<B>"CIRCUITO E MéTODO PARA ESTIMULAçãO DE UM APARELHO TELEFôNICO"<D>. A presente invenção se refere a um dispositivo elétrico (202, 301) para conectar um dispositivo de transferência de dados analógicos (202) por meio de uma unidade de controle (203) a um sistema de transferência digital, que compreende meios para conectar um dispositivo de transferência de dados com um cabo duplo (204). Além disso, o dito dispositivo compreende uma disposição de amplificador de corrente (214, 314, 340), para alimentar uma determinada corrente ao cabo duplo, um primeiro dispositivo de comutação de corrente (219) para comutar uma primeira corrente de controle à disposição de amplificador de corrente e um segundo dispositivo de comutação de corrente (220) para comutar uma segunda corrente de controle à disposição de amplificador de corrente. Os dispositivos de comutação de corrente (219, 220) são preferencialmente espelhos de correntes.
