Abstract

Circuitos Eletrónicos Um circuito eletrónico analógico é colocado entre o escritório central de um provedor de telecomunicações e o equipamento das instalações do cliente de um sistema de linhas digitais de assinante que usa fios de par trançado não blindado ("UTP"). O circuito eletrónico separa os sinais de downlink dos sinais de uplink com um primeiro misturador. Os sinais de voz, se presentes, são roteados pelo circuito eletrónico inalterado. Os sinais de downlink são amplificados, filtrados, novamente amplificados com um ou mais amplificadores de equalização de picos, depois, amplificados com drivers que fornecem a energia para acionar o sinal de downlink através de um segundo misturador para as linhas UTP para o equipamento das instalações do cliente. O circuito eletrónico separa os sinais de uplink dos sinais de downlink com o segundo misturador. Os sinais de uplink são amplificados, filtrados e novamente amplificados, depois, acionados sobre o UTP conectado ao escritório central através do primeiro misturador.
