Abstract

"SISTEMA DE TRANSMISSãO, TRANSMISSOR, RECEPTOR PROCESSO DE TRANSMISSãO E SINAL". Em um sistema de transmissão, o transmissor (2) contém um montador de quadros (8) para montar quadros contendo um cabeçalho e uma parte de "carga". O cabeçalho (22-1) contém um incdicador de validade (SSSSS) para indicar a validade de uma seq³ência de células ATM no quadro. Utilizando-se valores do indicador de validade (SSSSS) diferentes do valor do indicador de validade atribuído para células ATM válidas, torna-se possível transportar dados em um formato diferente de uma seq³ência de células ATM.
