Abstract

Patente de Invenção: <B>"PROCESSO PARA A TRANSMISSãO DE SINAIS DE DADOS EM LINHAS DE ASSINANTES ANALóGICAS"<D>.Uma transmissão de dados dos dois lados entre a instalação terminal de assinantes e a central de comutação telefónica, deve ocorrer também durante a transmissão de sinais de voz, e deve poder ser implementada com pouco dispêndio. é utilizado um sinal, de preferência, o sinal de impulso de tarifa produzido como sinal de suporte, pelo menos, no central de comutação telefónica para emprego de outro modo. De acordo com isso, existe a possibilidade de utilizar a infra-estrutura já existente.Invention Patent: <B> "PROCESS FOR THE TRANSMISSION OF DATA SIGNS IN ANALOGUE SUBSCRIBERS 'LINES" <D>. A data transmission on both sides between the subscriber terminal installation and the telephone switchboard, must also occur during transmission of voice signals, and it must be possible to implement it with little expense. a signal is used, preferably the tariff pulse signal produced as a support signal, at least in the telephone exchange for use in another way. Accordingly, there is a possibility to use the existing infrastructure.
