Abstract
SE PRESENTA UNA RED DE TELECOMUNICACIONES SDH (JERARQUIA DIGITAL SINCRONICA) QUE COMPRENDE UNA PLURALIDAD DE NODOS INTERCONECTADOS (1, 2, 3, 4). LOS CANALES DE TRABAJO (5, 6) ESTAN DEFINIDOS ENTRE RESPECTIVOS PARES DE NODO (1, 2 Y 3, 4) CON UN CANAL DE PROTECCION COMUN (5) QUE DA SERVICIO A UNA PLURALIDAD DE CANALES DE TRABAJO (5, 6) DE FORMA QUE EN EL CASO DE FALLO EN UN CANAL DE TRABAJO, LAS SEÑALES DE TRAFICO QUE PASAN DESDE UN PRIMER NODO (3) A UN SEGUNDO NODO (4) A LO LARGO DEL CANAL DE TRABAJO PRINCIPAL SON CONMUTADAS SOBRE EL CANAL DE PROTECCION (7). EL PRIMER NODO (3) ESTA ENTONCES OPERATIVO PARA TRANSMITIR UNA SEÑAL DE TRAZA DE CANAL JUNTO CON LAS SEÑALES DE TRAFICO QUE SIRVE PARA IDENTIFICAR EL CANAL RESPECTIVO. EL SEGUNDO NODO (4) ES OPERATIVO PARA MONITORIZAR LA PRESENCIA DE UNA SEÑAL DE TRAZA DE CANAL SOBRE EL CANAL DE PROTECCION (7) PARA LA CUAL ES EL NODO DE FINALIZACION Y DESPUES DE LA DETECCION DE LA MISMA PARA CONMUTAR LAS SEÑALES DE TRAFICO ASOCIADAS CON ESA SEÑAL DE TRAZA EN EL CANAL DE PROTECCION (7) DENTRO DEL SEGUNDO NODO (4) PARA LA CONEXION CON UN DESTINO ADELANTADO.
