Abstract
Patente de Invenção: <B>"SISTEMA DE COMUNICAçãO DE PAR TRANçADO"<D>. Sistema de comunicação para passagem de informação entre os serviços de informação e os dispositivos terminais através de uma rede de par de fios trançados. Os serviços de informação incluem uma central telefónica e outros serviços, tais como uma rede de dados e um sistema de distribuição por televisão. Os dispositivos terminais incluem telefones e outros dispositivos, tais como computadores e televisões. O sistema inclui uma interface de informação principal acoplada aos serviços de informação e uma rede de fiação de par trançado acoplada aos dispositivos terminais e à interface de informação principal. A rede de fiação inclui múltiplos pares telefónicos ativos para passagem de sinais de voz entre a central telefónica e os telefones. A interface de informação inclui circuito para combinação nos pares telefónicos ativos de (a) sinais telefónicos em uma banda de freq³ências telefónicas que passam entre a central telefónica e um ou mais telefones e (b) sinais de alta freq³ências em uma alta banda de freq³ências maiores do que aqueles da banda de freq³ências telefónicas que passam informação entre os outros serviços de informação e um ou mais dos dispositivos terminais.Invention Patent: <B> "TWISTED PAIR COMMUNICATION SYSTEM" <D>. Communication system for passing information between information services and terminal devices through a twisted pair network. Information services include a telephone exchange and other services, such as a data network and a television distribution system. Terminal devices include phones and other devices, such as computers and televisions. The system includes a main information interface coupled to the information services and a twisted pair wiring network coupled to the terminal devices and the main information interface. The wiring network includes multiple active telephone pairs for the passage of voice signals between the exchange and the telephones. The information interface includes a circuit for combining in the active telephone pairs of (a) telephone signals in a band of telephone frequencies that pass between the exchange and one or more telephones and (b) high frequency signals in a high frequency band. than those in the telephone frequency band that pass information between other information services and one or more of the terminal devices.
