Abstract

"DISPOSITIVO PARA MONITORAMENTO DE QUALIDADE E MéTODO PARA SISTEMA DE COMUTAçãO ATM". Em um dispositivo de monitoramento da qualidade para monitorar a qualidade de células ATM armazenadas em um registro auxiliar, um contador programável é provido para decrementar um valor de contagem em resposta a cada célula enviada do registor auxiliar para definir uma janela de tempo de tamanho variável. Responsivo a cada célula descartada do registro auxiliar, um valor predeterminado é adicionado ao valor de contagem do contador programável para produzir um valor somado e o contador programável é atualizado com o valor somado um contador de perda de célula incrementa seu valor de contagem em resposta a cada célula que é descartada do registro auxiliar dentro da janela de tempo. Um circuito de decisão produz um sinal de qualidade baixa quando o valor de contagem do contador de perda de célula for maior que um valor limite.
