  Einrichtung zum Anschluss eines Anrufbeantworters 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

    B.Leitungen--A, B- unmöglich   wird. 



   Durch das Sperrglied-Sp-wird aber nicht nur der Gleichstrom gesperrt, sondern auch ein Wechselstrom, insbesondere der Rufwechselstrom gedämpft, so dass ein ankommender Ruf den   Anrufbeantworter --2-- nicht   in Betrieb zu setzen vermag. Aus diesem Grunde ist vor den eigentlichen Rufbeantworter-2-ein insbesondere den Rufwechselstrom verstärkender Verstärker - geschaltet, der zweckmässigerweise mit dem eigentlichen   Rufbeantworter-2-in   einem Gerät zusammengebaut ist. 



   Selbstverständlich ist die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt. So kann an die Stelle eines Relais als Sperrvorrichtung auch eine Transistorschaltung, eine Diodenschaltung od. dgl. treten. 



   PATENTANSPRÜCHE : 
1. Einrichtung zum Anschluss eines Anrufbeantworters an eine, zu einem Teilnehmer eines Gruppenschlusssystems führende Femsprechteilnehmerleitung, insbesondere eines Viertelanschlusses mit 
 EMI2.1

    B. Lines - A, B- becomes impossible.



   The blocking element-Sp- not only blocks the direct current, but also damps an alternating current, in particular the ringing alternating current, so that an incoming call cannot put the answering machine --2-- into operation. For this reason, in front of the actual answering machine 2, an amplifier, in particular, which amplifies the alternating ringing current, is connected, which is expediently assembled in one device with the actual answering machine 2.



   Of course, the invention is not limited to the illustrated embodiment. Thus, instead of a relay as a blocking device, a transistor circuit, a diode circuit or the like can be used.



   PATENT CLAIMS:
1. Device for connecting an answering machine to a telephone subscriber line leading to a subscriber of a group locking system, in particular a quarter connection
 EMI2.1

Claims (1)

b)(a, b) bzw. den Teilnehmerapparat anschliessenden Anschaltrelais (S) liegenden Arbeitskontakt (sp) aufweist. b) (a, b) or the connection relay (S) connected to the subscriber set has normally open contact (sp). 3. Anrufbeantworter für eine Einrichtung nach Anspruch 1 oder 2, dadurch gekenn- zeichnet, dass zur Verstärkung des durch das Sperrglied gedämpften Rufstromes ein diesen verstärkender Verstärker (3) vorgesehen ist. 3. Answering machine for a device according to claim 1 or 2, characterized in that an amplifier (3) is provided to amplify the ringing current damped by the blocking element.
