Abstract

TERMINAL CELULAR FIJO PARA SERVICIOS DE TELECOMUNICACIONES A DOS HILOS. PARA ACCEDER A UNA RED DE COMUNICACIONES MOVILES Y PROVEER SERVICIOS BASICOS DE TELECOMUNICACIONES DE LA RED PUBLICA CONMUTADA A UN TERMINAL TELEFONICO (TT2) ORDINARIO CONECTADO A EL. DICHO TERMINAL SE DERIVA DE UN TERMINAL CELULAR MOVIL GSM, CON TRANSMISION A CUATRO HILOS DURANTE TODO EL TRAYECTO, COMPRENDIENDO UN CIRCUITO DE CONVERSION A DOS HILOS (H) CONECTADO ENTRE LOS PARES DE TRANSMISION (TP) Y DE RECEPCION (RP) Y LA LINEA DE ABONADO (SL) DEL TERMINAL TELEFONICO (TT2). COMPRENDE ADEMAS UN CANCELADOR DE ECO (EC) PREVIO AL CIRCUITO DE CONVERSION A DOS HILOS (H), PARA SUBSTRAER PARTE DE UNA PRIMERA SEÑAL (FS) CON DESTINO AL TERMINAL TELEFONICO (TT2) DE UNA SEGUNDA SEÑAL (SS) PROCEDENTE DEL MISMO Y COMPENSAR DE ESTA FORMA PARTE DEL ECO PRODUCIDO PRINCIPALMENTE EN EL TERMINAL TELEFONICO (TT2) Y EN EL CIRCUITO DE CONVERSION A DOS HILOS (H).
