Abstract

UN SISTEMA DE COMUNICACION POR FAX Y UN APARATO DE COMUNICACION QUE REDUCE EL TIEMPO DE PERDIDA DEBIDO A LA SINCRONIZACION DE TRANSMISION/RECEPCION Y ACORTA EL TIEMPO DE COMUNICACION. TAMBIEN ACORTAN EL TIEMPO DE COMUNICACION EN UN MODO DE COMUNICACION DOBLE COMPLETO Y PERMITEN LA CONMUTACION APROPIADA DE LA COMUNICACION DOBLE COMPLETA EN EL RELEVO ENTRE TRANSMISION/RECEPCION. LAS SEÑALES DIS-CFR, LA SEÑALES EOP-DCN, LAS SEÑALES NSS-TSI Y LAS SEÑALES TSI-DCS DE UN PROTOCOLO DE COMUNICACION POR FAX ESTAN CONECTADAS POR SEÑALES DE SINCRONIZACION DE MANERA QUE LAS SEÑALES DE SINCRONIZACION SEAN ENVIADAS INCLUSO DESPUES DE ENVIAR LA SEÑAL DE PROTOCOLO. ASI EL ENVIO DE LA SEÑAL DE SINCRONIZACION DURANTE UN SEGUNDO CUANDO LA SIGUIENTE SEÑAL DE PROTOCOLO ES ENVIADA NO ES NECESARIO Y SE REDUCE EL TIEMPO REQUERIDO PARA LA SEÑAL DE PROTOCOLO. SE ENVIA UNA SEÑAL ANSAM QUE DESACTIVA LA FUNCION DE UN SUPRESOR DE ECO CUANDO SE DETECTA LA LLAMADA Y LA ESTACION DE LLAMADA ENVIA A CONTINUACION UNA SEÑAL DEPROTOCOLO Y UNA SEÑAL DE IMAGEN DE MANERA QUE NO CAUSE LA INTERRUPCION DE LA SEÑAL DE 50 MS O MAS, Y EN EL RELEVO DE TRANSMISION/RECEPCION EN EL EXTREMO DE LA SEÑAL DE IMAGEN DE LA ESTACION DE LLAMADA, UNA ESTACION LLAMADA ENVIA UNA SEÑAL ANSAM Y ENVIA UNA SEÑAL DE PROTOCOLO.
