Abstract

EL INVENTO CONCIERNE A UN SISTEMA DE TRANSMISION EN EL QUE TIENEN QUE SER MULTIPLEXADAS Y ENVIADAS UNA MULTITUD DE CORRIENTES DE DATOS ENTRE EQUIPOS DE TRANSMISION Y RECEPCION DE DATOS. EN LA PARTE TRANSMISORA EL SISTEMA CONSTA DE UNA PLURALIDAD DE CARTAS TRIBURARIAS DE TRABAJO (51, 52) CADA UNA CON UN PUERTO DE ENTRADA (57) CONECTADO A UN TRIBUTARIO INDIVIDUAL PARA SER ENVIADO A UN MULTIPLEXOR ASOCIADO, Y UNA TARJETA TRIBUTARIA DE RESERVA (56) OPERATIVA PARA REEMPLAZAR UNA TARJETA DE TRABAJO ESTROPEADA. TODAS LAS TARJETAS TRIBUTARIAS DE TRABAJO (51 - 55) ESTAN INTERCONECTADAS POR UNA LINEA COMUN (60) QUE LLEVA AL PUERTO DE ENTRADA (57) DE LA TARJETA TRIBUTARIA DE RESERVA (56) PERO QUE EN OPERACION NORMAL ESTA AISLADA DE DICHA LINEA POR UN BUFFER DE GANANCIA UNITARIA CONTROLABLE 58. CADA TRIBUTARIA QUE TIENE QUE SER TRANSMITIDA SE CONECTA A UN PUERTO DE ENTRADA (57) DE UNA TARJETA TRIBUTARIA DE TRABAJO Y TIENE UNA LINEA RAMIFICADA QUE ESTA CONECTADA A LA RAMA COMUN (60) VIA EL BUFFER (58) LLEVADO EN OTRA TARJETA TRIBUTARIA, CAUSANDO LA DETECCION DEL FALLO DE UNA TARJETA TRIBUTARIA EL ACCIONAMIENTO DE LA TARJETA TRIBUTARIA DE TRABAJO PARA CONECTAR LA TRIBUTARIA A DICHA TARJETA TRIBUTARIA DE RESERVA.
