Abstract

SISTEMA DE PROTECCION CONTRA LOS ERRORES PARA LA TRANSMISION ASINCRONA BIDIRECCIONAL DE DATOS. CONSISTE EN UTILIZAR POR CARACTER UN MOMENTO DE PARIDAD, EN EL QUE SE UTILIZA EL METODO DE RETRANSMISION CONTINUA ARQ-NAK, PREVIENDOSE LA DETECCION Y CORRECCION DE ERRORES. LA INFORMACION ES TRANSMITIDA POR BLOQUES O PALABRAS DE CODIGO, ESTANDO FORMADA CADA PALABRA DE CODIGO POR UN BLOQUE DE DIECISIETE OCTETOS DE LOS QUE LOS OCTETOS 1 A 15 ESTAN CONSTITUIDOS POR LOS CARACTERES A TRANSMITIR CODIFICADOS SOBRE SIETE ELEMENTOS BINARIOS B1 A B7, SIENDO EL 8.O ELEMENTO BINARIO DE CADA OCTETO EL DE PARIDAD, CUYO 16.O OCTETO ES EL DE CONTROL DE LA PALABRA DE CODIGO Y CUYO 17.O OCTETO ES EL DE VALIDACION DE LA PALABRA DE CODIGO. COMPRENDE UN CONCENTRADOR (S), UN TERMINAL (T) Y UNA LINEA TELEFONICA (L) QUE LOS UNE. INTEGRA (S) UNA UNIDAD DE GESTION CENTRAL (UGC), UN CONVERTIDOR PARALELO/SERIE (CPS1), UN CONVERTIDOR SERIE/PARALELO (CSP1), UN MODEN (Y1) Y UN GENERADOR DE PALABRAS DE CODIGO (GEN). CONSTA (T) DE UNA UNIDAD DE GESTION TERMINAL (UGT), UN CONVERTIDOR SERIE/PARALELO (CSP2), UN CONVERTIDOR PARALELO/SERIE (CPS2), UN MODEN (Y2) ELEMENTO BINARIO DE CADA Y UN RECEPTOR DE PALABRAS DE CODIGO (REC).
