Abstract

"SISTEMA DE TRANSPORTE DE CORRENTE DE TELEFONIA DIGITAL". Se descreve um sistema de distribuição para a distribuição de feixes de dados de telefonia digital para utilização em uma edificação ou unidade fabril, que utiliza, como ligação de comunicação, linhas de energia AC (105). Este sistema de distribuição comunica sinais e dados sem a necessidade de linhas de telefone contínuas. Este sistema provê uma unidade base (104), conectada a uma unidade de interface de assinante (102), a qual, por sua vez, se encontra conectada a uma rede e comunicação pública. A unidade básica (104), ainda provê uma interface de linha de energia AC (105), através da qual, sinais de comunicação são comunicados a unidades de extensão (106a, 106b,... 106e). As unidades de extensão (106a, 106b,... 106e) suportam dispositivos de comunicação de telecomunicação padrão, para usuários, tais como telefones, quadros de comutação, aparelhos de fax e modems. A forma de apresentação preferida desta invenção utiliza um esquema de codificação e de decodificação FSK a fim de suportar a comunicação dos sinais digitais e a fim de aperfeiçoar a qualidade do sistema, reduzindo erros e apresentando uma maior imunidade aos ruídos."DIGITAL TELEPHONY CHAIN TRANSPORT SYSTEM". A distribution system is described for the distribution of digital telephone data bundles for use in a building or factory, which uses AC power lines as a communication link (105). This distribution system communicates signals and data without the need for continuous telephone lines. This system provides a base unit (104), connected to a subscriber interface unit (102), which, in turn, is connected to a network and public communication. The basic unit (104) still provides an AC power line interface (105), through which communication signals are communicated to extension units (106a, 106b, ... 106e). The extension units (106a, 106b, ... 106e) support standard telecommunication communication devices for users, such as telephones, switchboards, fax machines and modems. The preferred form of presentation of this invention uses an FSK encoding and decoding scheme in order to support the communication of digital signals and in order to improve the quality of the system, reducing errors and showing greater immunity to noise.
