Abstract

DISPOSICION DE CONEXIONES PROPUESTA PARA TERMINALES TELEFONICOS QUE A TRAVES DE UNA UNIDAD DE CONEXION A LA RED SE CONECTAN A LA RED DE TELECOMUNICACION (YSDN) DIGITAL QUE INTEGRA EL SERVICIO, QUE AL FALLAR EL ABASTECIMIENTO DE LA ENERGIA GOBIERNA EN SERVICIO DE EMERGENCIA EL ABASTECIMIENTO DESDE LA CENTRAL TELEFONICA, DE TAL MANERA QUE EN EL ESTADO DE REPOSO SE REDUCE A UN MINIMO LA ABSORCION DE ENERGIA DEL TERMINAL TELEFONICO. CON ESTE OBJETO SE DESCONECTA LA TENSION PARA CONSUMIDORES INTERNOS DEL TERMINAL TELEFONICO Y NO SE CONECTA DE NUEVO HASTA QUE ESTE ESTA EN ACTIVO, ES DECIR CUANDO HAY OCUPACION POR LLAMADA DESDE EL TERMINAL O AL TERMINAL.
