Abstract

APARATO, EN UN SISTEMA DIGITAL DE COMUNICACIONES, PARA CONECTAR TERMINALES DIGITALES A UN NUDO TERMINAL.CONSTA DE UN DISPOSITIVO (A LA IZQUIERDA DE LA LINEA DISCONTINUA IÑI) QUE CONECTA TERMINALES DI GITALES A UN NUDO TERMINAL QUE ESTA A SU VEZ, CONECTADO CON UNA CENTRAL DIGITAL. EL NUDO TERMINAL (A LA DERECHA DE LA LINEA DISCONTINUA IÑI) CONTIENE MEDIOS DIRECTORES (9) PARA TRANSMITIR EN UN PRIMER ESTADO UNA SEÑAL INDICADORA DE ESTADO, A LOS TERMINALES Y A LA CENTRAL Y PARA ENVIAR EN UN SEGUNDO ESTADO UN BLOQUE O PAQUETE DE INFORMACION RECIBIDO (41, 42, 43)DESDE UNA TERMINAL A LA CENTRAL, CON EL TRANSMISOR DEL LADO DE LA CENTRAL (10), Y A TODAS LAS TERMINALES CON LOS TRANSMISORES (44, 54 Y 46). LOS TERMINALES TIENEN MEDIOS PARA TRANSMITIR UN BLOQUE DE INFORMACION EN RESPUESTA A LA RECEPCION DE LA SEÑAL INDICADORA DE ESTADO UN NUMERO DE VECES DETERMINADO, CON LO CUAL REPONEN A LOS MEDIOS DIRECTORES (9) A SU SEGUNDO ESTADO.
