Abstract

"MéTODO E APARELHO PARA O FORNECIMENTO DE INTEGRIDADE DE CONTAGEM DE BITS E TRANSFERêNCIA DE DADOS SìNCRONOS SOBRE UM CANAL QUE NãO PRESERVE A SINCRONIZAçãO". A integridade da sincronização e da contagem de bits, de uma corrente de dados síncrona, é preservada de ponta a ponta mesmo à medida em que for transmitida via um meio que não preserve a natureza síncrona da corrente de dados síncrona. Uma unidade de equipamento terminal (100) produz uma corrente de bits com taxa constante, que é fornecida a uma unidade de comunicação (110). A unidade de comunicação (100) produz um primeiro quadro de dados que compreende um primeiro conjunto de bits proveniente da corrente de bits com taxa constante e um primeiro valor de campo de comprimento. Um segundo quadro de dados é produzido, o qual compreende um segundo conjunto de bits proveniente da corrente de bits com taxa constante e um segundo campo de comprimento. Um terceiro quadro de dados é produzido, o qual compreende um terceiro conjunto de bits a partir da corrente de bits com taxa constante e um terceiro valor de campo de comprimento. Os primeiro, segundo e terceiro quadros de dados são transmitidos a uma unidade base (118) que coloca o primeiro conjunto de bits a partir do primeiro quadro formando uma fila (150). Um conjunto de bits de preenchimento igual ao número máximo de bits contidos em qualquer quadro é colocado então na fila (150). A unidade base (118) determina então o número de bits no segundo conjunto de bits do terceiro quadro de dados, com base no primeiro valor de campo de comprimento e no terceiro valor de campo de comprimento, A unidade base (118) sobregrava os bits preenchimento em excesso na fila (150) com o terceiro conjunto de bits. O número de bits de preenchimento em excesso é equivalente à diferença existente entre o número máximo possível de bits que pode ficar contido em qualquer quadro e o número de bits no segundo conjunto de bits.
