Abstract

EN UNA RED SINCRONIZADA HAY QUE CONTROLAR LA CALIDAD DE LAS SEÑALES DIGITALES TRANSMITIDAS, MEDIANTE DISTRIBUIDORES DIGITALES INSTALADOS A LO LARGO DEL TRAYECTO, TRANSMITIENDOSE A SU VEZ LOS DATOS A UN SISTEMA DE CONEXIONES DE MANDO CENTRAL. SE SABE CON TRANSMITIR UNA SEÑAL STM-1 EN EL CABEZAL DE UN CONTENEDOR (VC-4) A UNA HENDIDURA B3 PARA EL CONTROL DE PARIDAD, DESDE LA FUENTE HASTA LA HONDONADA CON UNA PALABRA DE CODIGO DE BIP-8 (BIT INTERLEAVED PARITY 8 CODE). AHORA ESTA PALABRA DE CODIGO SE TRANSMITE ADICIONALMENTE COMO CONTROL B4 A UNA HENDIDURA TEMPORAL Z (Z4) LIBRE DEL CABEZAL, SE VALORA EN CADA DISTRIBUIDOR DIGITAL Y PASA DE NUEVO A LA CONDUCCION. DADO QUE CADA MODIFICACION EN EL CONTENEDOR (VC-4) FALSEA EL CONTROL B3, SE INTRODUCE UNA PALABRA DE CODIGO DE CORRECCION EN OTRA HENDIDURA Z (Z5) QUE ELIMINA LA MODIFICACION DE LA PALABRA DE CODIGO BIP-8 EN LA PRIMERA HENDIDURA TEMPORAL Z (Z4). ESTE PROCEDIMIENTO SE PUEDE UTILIZAR EN UNA RED SINCRONIZADA, DONDE SE TRANSMITE UN CONTENDOR VIRTUAL (VC-4) PARA 149,72 MBIT/S.
