Abstract

EL INVENTO TRATA DE UN ELEMENTO DE CONMUTACION DE DATOS TRANSMITIDOS POR MULTIPLEX TEMPORAL ASINCRONO QUE COMPRENDE UNOS CIRCUITOS DE RECEPCION (CR1/I) QUE SUMINISTRAN UNAS CELUCLAS RECIBIDAS POR UNAS UNIONES DE ENTRADAS, UNOS CIRCUITOS DE EMISION (CT1/J) QUE ENCIAN UNAS CELULAS RETRANSMITIDAS EN UNAS UNIONES DE SALIDA, UNA MEMORA TAPON (MT) QUE REGISTRA CELULAS RECIBIDAS Y LIBERA LAS CELULAS A RETRANSMITIR, ASI COMO UN DISPOSITIVO DE SEÑALIZACION (SMT) DE LA MEMORIA TAPON QUE COMPRENDE UNA FUENTE DE SEÑAS DE REGISTRO (SAE) Y UNA FUENTE DE SEÑAS DE LECTURA (FS1/J). EL ELEMENTO DE CONMUTACION COMPRENDE TAMBIEN UN CIRCUITO DE INHIBICION DE REGISTRO (PI) ACONDICIONADO POR UNA SEÑAL (ADL) QUE NACE DE UN CONTENIDO AL MENOS DE UNA CELULA RECIBIDA O UNA SEÑAL (TLE) NACIDA DE LA AUSENCIA DE CELULA RECIBIDA Y QUE SUMINISTRA UNA SEÑAL DE INHIBICION (SPI) Y LA FUENTE DE SEÑAS COMPRENDE UN DISPOSITIVO DE INHIBICION (PAC,PAL) INFLUENCIADO POR DICHA SEÑAL DE INHIBICION (SPI), DE TAL FORMA QTUE NINGUNEMPLAZAMIENTO SE MEMORIA SEA ENTONCES OCUPADO EN LA MEMORIA TAPON (MT).
