ADEMAS ESTA INSTALACION TELEFONICA TIENE LA VENTAJA DE QUE SOLO SE REQUIERE UNA RED CON N+1 CONDUCTORES HACIA LOS PUESTOS TELEFONICOS INTERIORES, EN QUE N CORRESPONDE AL NUMERO DE LOS PUESTOS TELEFONICOS INTERIORES.TELEPHONE INSTALLATION WITH A DOOR STATION AND AT LEAST ONE INTERNAL TELEPHONE POST. A TELEPHONE INSTALLATION IS CREATED, IN WHICH THE CALL SIGNAL IS GENERATED CENTRALLY AND CAN BE INDIVIDUALLY CONTRIBUTED TO THE INTERNAL TELEPHONE POSTS WITHOUT AFFECTING THE OCCUPATION OF THE TELEPHONE INSTALLATION JOINED BY THE INTERIOR TELEPHONE POSITION THE TRANSMISSION OF A DOOR OPENER SIGNAL FROM THE INTERNAL TELEPHONE POSTS. IN ADDITION, THIS TELEPHONE FACILITY HAS THE ADVANTAGE THAT ONLY A NETWORK WITH N + 1 CONDUCTORS IS REQUIRED TOWARDS INTERNAL TELEPHONE POSTS, IN WHICH IT CORRESPONDS TO THE NUMBER OF INTERNAL TELEPHONE POSTS.
