Abstract

Patente de Invenção: <B>"SISTEMA DE TRANSMISSãO DE INFORMAçõES, PARTICULARMENTE SISTEMA TELEFôNICO"<D>. Sistema de transmissão de informações para transmissão de informações de um ponto central, por exemplo, uma estação automática (1), para um ponto periférico, por exemplo, um aparelho terminal de assinante (4), sendo que o ponto central (1) está ligado através de um transformador analógico/digital (5) bidirecional, central, e uma linha de transmissão (11) analógica com um transformador analógico/digital (7)bidirecional, no lado central transformador analógico/digital (7) bidirecional, no lado central, esse que em sua saída ou entrada correspondente está ligado através de um trajeto de transmissão digital e pontos de intersecção associados aos terminais de linha com um transformador analógico/digital (8) bidirecional, no lado periférico, que no lado da saída ou da entrada está ligado através de uma outra linha de transmissão (30) analógica com o ponto periférico, sendo que a linha característica de transformador do transformador analógico/digital (7)bidirecional, no lado central, bem como do transformador analógico/digital (8) bidirecional, no lado periférico, é linear e o trajeto de transmissão está formado por um trajeto de transmissão de alta velocidade (12, 21, 31).Invention Patent: <B> "INFORMATION TRANSMISSION SYSTEM, PARTICULARLY TELEPHONE SYSTEM" <D>. Information transmission system for transmitting information from a central point, for example, an automatic station (1), to a peripheral point, for example, a subscriber terminal device (4), the central point (1) being connected via a bidirectional analog / digital transformer (5), central, and an analog transmission line (11) with a bidirectional analog / digital transformer (7), on the central side bidirectional analog / digital transformer (7), on the central side , which at its corresponding output or input is connected via a digital transmission path and intersection points associated with the line terminals with a bi-directional analog / digital transformer (8), on the peripheral side, which on the output or input side is connected via another analog transmission line (30) with the peripheral point, the transformer characteristic line of the analog / digital transformer (7) bidir on the central side, as well as the analog / digital transformer (8) bidirectional, on the peripheral side, it is linear and the transmission path is formed by a high speed transmission path (12, 21, 31).
