Abstract

EL KIT DE ABONADO DISEÑADO COMO KIT PARA MARCADO DIRECTO Y PARA UN PROCESO DE SEÑALIZACION DE CORRIENTE CONTINUA ENTRE CENTRAL PRIVADA DE TELEFONOS (NVST) Y CENTRAL TELEFONICA PUBLICA (OVST), PRESENTA UNA BOBINA REPETIDORA (U) ATRAVESADA TANTO POR CORRIENTE ALTERNA DE VOZ COMO TAMBIEN CORRIENTE DE ALIMENTACION PARA EL DESACOPLADO DE LA SEÑAL DE VOZ, CON LO CUAL SE EVITA UNA BOBINA DE REACTANCIA DE ALIMENTACION. PARA COMPENSAR LAS ASIMETRIAS CAUSADAS POR LOS ELEMENTOS DE SEÑALIZACION (RFA, RFB) INTRODUCIDAS EN LOS HILOS CONDUCTORES, LOS CUALES PUEDEN CONDUCIR CON ENTREMEZCLADOS EN LOS HILOS CONDUCTORES DE LOS ABONADOS (A,B) A PERTURBACIONES DE LOS ABONADOS, POR LO MENOS ESTA CONECTADO EN PARALELO A UNO DE LOS ELEMENTOS DE SEÑALIZACION, UN ELEMENTO RC (RSY/CSY).
