Abstract

UN NODO REGENERATIVO PARA UNA RED DE COMUNICACIONES PARA USO CON CANALES DE DATOS CON DOMINIO DE TIEMPO MULTIPLEXADO (TDM) U QUE TIENE UN RECEPTOR DE RETRAO DE BLOQUEO (6) PARA BLOQUEAR UN CANAL MODULADO MEEIANTE SU SECUENCIA DE MODULACION ASOCIADA O UNA SECUENCIA MODULADA COMUN; UN TRANSMISOR ()4) ESCLAVO AL RECEPTOR (6) PARA PROPORCIONAR DATOSPARA SER TRANSMITIDOS POR EL NODO EL CUAL HA SIDO MODULADO MEDIANTE LA SECUENCIA DE MODULADA DEL NODO O UNA SEÑAL DE CANAL VACIO MODULADA POR LA SECUENCIA MODULADA COMUN EN FASE DE SINCRONIZACION CON EL CANAL TDM PARA EL CUAL EL RECEPTOR ESTA BLOQUEADO; Y UN REGENERADOR (8) PARA REGENERAR LOS CANALES TDM RECIBIDOS POR LOS CANALES TDM CON LOS DATOS DE TRANSMISION SOBREESCRIBEINDO EL CANAL DE RETARDO DE BLOQUEO. UN NODO QUE QUERE REALIZAR UNA LLAMADA ALCANZA Y BLOQUEA AL CANAL QUE TIENE UN CANAL VACIO DE SECUENCIA MODULADA MEDIANTE LA SECUENCIA MODULADA COMUN Y A SU VEZ BLOQUEA CON RETARDO PARA TRANSMITIR UNA SEÑAL MODULADA MEDIANTE LA SECUENCIA DE NODOS DE DESTINO. EL OTRO NODO SERA POSTERIORMENTE BLOQUEADO CON RETARDO A ESTE CANAL Y TRANSMITE AL PRIMER NODO EN EL MISMO CANAL TDM QUE USA LA SECUENCIA MODULADA DEL PRIMER NODO. EL INVENTO ENCUENTRA PARTICULAR APLICACION EN REDES TELEFONICAS DE COMUNICACIONES DE VIDEO DE DOBLE CAMINO.
