Abstract

"PROCESSO E DISPOSITIVO PARA A CONVERSãO DE DADOS DE VOZ CODIFICADOS". A presente invenção refere-se a um processo e um dispositivo para a conversão de dados de voz transmitidos em um primeiro ModusCodec de voz para dados de voz transmitidos em um segundo Modus-Codec de voz dentro de uma central de comutação de uma rede de comunicações baseada no padrão UMTS ou no padrão GERAN, sendo que os dados de voz, desviando-se de um campo de acoplamento de Time-DivisionMultiplexing e de dispositivos de compressão e de descompressão para comprimir e descomprimir os dados de voz modulados linearmente por pulsos em código, para uma entrada de um dispositivo de codificação (6b, 6a).
