Abstract

UN SISTEMA DE TRANSMISION FACSIMIL REALIZA UNA TRANSMISION FACSIMIL ENTRE UNA ESTACION TRANSMISORA Y UNA ESTACION RECEPTORA. LA ESTACION TRANSMISORA REALIZA UNA LLAMADA A LA ESTACION RECEPTORA, DETECTA UNA SEÑAL DE IDENTIFICACION DE ESTACION LLAMADA (CED) RECIBIDA DE LA ESTACION RECEPTORA, TRANSMITE UNA SEÑAL DE REPETICION (REP) A LA ESTACION RECEPTORA, CUANDO LA SEÑAL DE IDENTIFICACION DE ESTACION LLAMADA (CED) SE DETECTA, DETECTA SI LA SEÑAL DE IDENTIFICACION DE ESTACION LLAMADA (CED) RECIBIDA DESDE LA ESTACION RECEPTORA SE DETIENE O NO DENTRO DE UN TIEMPO PREDETERMINADO, E INICIA UNA TRANSMISION FACSIMIL DE CONFORMIDAD CON UN PROCEDIMIENTO DE TRANSMISION DE ALTA VELOCIDAD SI LA PARADA DE LA SEÑAL DE IDENTIFICACION (CED) DE LA ESTACION LLAMADA SE DETECTA DENTRO DE UN TIEMPO PREDETERMINADO. EL PROCEDIMIENTO DE TRANSMISION DE ALTA VELOCIDAD EMPLEA UN PROTOCOLO QUE REQUIERE UN TIEMPO MAS CORTO QUE UN PROTOCOLO DE PROCEDIMIENTO DE TRANSMISION ESTANDAR, QUE ESTA CONFORME CON LAS RECOMENDACIONES CCITT. LA ESTACION RECEPTORA TRANSMITE LA SEÑAL DE IDENTIFICACION DE ESTACION LLAMADA (CED) CUANDO LA LLAMADA SE RECIBE DESDE LA ESTACION DE TRANSMISION, DETECTA LA SEÑAL DE REPETICION (REP) RECIBIDA DE LA ESTACION DE TRANSMISION, Y DETIENE LA TRANSMISION DE LA SEÑAL DE IDENTIFICACION DE ESTACION LLAMADA (CED) CUANDO SE PARA LA SEÑAL DE REPETICION (REP).
