Abstract

"ESTáGIO COMUTADOR DE TEMPO, E, ESTRUTURA DE COMUTAçãO". A invenção refere-se à preservação da integridade de seq³ência (TSSI) e à integridade de quadro (TSFI) na comutação das conexões de banda larga através de um comutador ou um estágio comutador. A memória de fala (17) em um estágio comutador (6.n) no comutador é estendida para incluir as posições de armazenamento (44.n) que em número correspondem ao número de intervalos de tempo nos dois quadros. Essas posições de armazenamento são dispotas em duas partes (48,49) do mesmo tamanho na memória de fala (17). Adicionalmente, é fornecida uma unidade de controle de retardo (26) no estágio comutador de tempo (6.n) para a geração da informação de retardo com base na informação de controle na memória de controle (23) do estágio comutador (6.n) e uma parte determinada da informação de contador de um circuito de contador de intervalo de tempo (28). Essa informação de retardo controle, para cada intervalo de tempo, para/de (dependendo de se a memória de fala (17) é disposta em um estágio de saída ou um estágio de entrada) que uma das primeira (48) e segunda partes (49) da memória de fala (17) esses dados são comutados.
