Abstract

"SISTEMA DE MEDIçãO E MéTODO PARA A DETECçãO DE TERMINAL DENTRO DE UM AMBIENTE ADSL". Apresentam-se um método e aparelho que irão detectar a presença de terminações em um ambiente ADSL. O método e o aparelho atualmente revelados aplicam uma tensão com valor lentamente variado ao laço do assinante enquanto se efetua a medição do fluxo de corrente elétrica. A tensão com valor variado é capaz de passar através dos indutores. A taxa de fluxo de corrente elétrica é discernível quando os diodos zener do Semi oscilador, o Divisor dos Recintos e qualquer Oscilador Eletrónico começarem a conduzir. Assim se obtém a detecção no tempo (tensão) de dispositivos que possam existir na linha submetida a teste. Através da análise de um gráfico da corrente elétrica na linha na medida em que se aplica uma tensão com valor variado, as alterações no gráfico oferecem uma indicação de que uma terminação está presente. A localização da alteração na corrente elétrica com respeito a tensão aplicada proporciona uma indicação do tipo de terminação detectada.
