Description
Der Erfindung liegt die Aufgabe zugrunde, die bekannten, zusammengestellt. Bei jedem Tastendruck bestimmt der Mikro-mit einer Tastatur für die Wahl von Rufnummern versehenen 60 prozessor P den Impulszug, der der gewählten Ziffer entspricht Fernsprecher bzw. Münzfernsprecher zu vereinfachen. und der in die Teilnehmerleitung eingegeben werden soll. Er The invention is based on the object, the known, compiled. Each time the button is pressed, the microprocessor P, equipped with a keyboard for dialing telephone numbers, determines the pulse train that corresponds to the dialed number to simplify the telephone or coin operated telephone. and which is to be entered into the subscriber line.

Umschaltkontakt FI in die Lage F umgeschaltet werden. Bei abgenommenem Hörer E wird dann bei jedem Tastendruck die der gewählten Ziffer entsprechende Frequenz durch den Mikroprozessor P bestimmt. Der Mikroprozessor P steuert das erste Relais Ri an, so dass sein Impulskontakt Li geschlossen wird. Er gibt gleichzeitig an den Multifrequenz-Generator G einen Befehl ab zum Aussenden einer der gewählten Ziffer entsprechenden Frequenz, die über den Transformator TR2 in die Teilnehmerleitung gelangt. Changeover contact FI can be switched to position F. When the receiver E is picked up, the frequency corresponding to the selected digit is then determined by the microprocessor P each time the button is pressed. The microprocessor P controls the first relay Ri so that its pulse contact Li is closed. At the same time, it issues a command to the multifrequency generator G to send out a frequency corresponding to the dialed digit, which frequency reaches the subscriber line via the transformer TR2.
Wird die beschriebene Schaltungsanordnung bei einem Münzfernsprecher verwendet, so erhält der Mikroprozessor P während des Gespräches von im Münzteil vorhandenen, in der Zeichnung nicht gezeigten Stromkreisen über die Leitung 7 Informationen über den Stand des aus den eingeworfenen Münzen bestehenden Guthabens, so dass er den Augenblick bestimmen kann, in welchem ein Nachzahlaufforderungssignal an den Hörer E abgegeben werden soll. Das Signal wird vom Multifrequenz-Generator G erzeugt und über den Übertrager TR3 dem Hörer E zugeleitet. Der Transistor T ist dabei durch If the circuit arrangement described is used in a coin operated telephone, the microprocessor P receives information about the status of the credit balance consisting of the inserted coins via the line 7 during the conversation from circuits present in the coin part, not shown in the drawing, so that it can determine the moment can in which a post-payment request signal is to be issued to the listener E. The signal is generated by the multi-frequency generator G and fed to the receiver E via the transmitter TR3. The transistor T is through

Aussteuerung seiner Basis durch den Mikroprozessor P leitend. Control of its base by the microprocessor P conductive.
Die beschriebene Schaltungsanordnung ermöglicht, die bekannte Tastatur ohne jedweden zusätzlichen Schaltungsaufwand in Fernsprechnetzen mit Impuls- und Frequenzwahl 5 sowohl für Fernsprecher als auch für Münzfernsprecher zu verwenden. Ausserdem bietet die Verwendung des Mikroprozessors P die Möglichkeit, die Telefonnummern, bei denen eine Verbindung lediglich über die Vermittlungsstelle hergestellt werden kann, im Mikroprozessor P zu speichern. Dies hat den 10 Vorteil, dass die entsprechenden Leitungen durch unbefugte Anrufe nicht blockiert werden. The circuit arrangement described makes it possible to use the known keyboard without any additional circuitry in telephone networks with pulse and frequency selection 5 for both telephone and coin operated telephone. In addition, the use of the microprocessor P offers the possibility of storing the telephone numbers, in which a connection can only be established via the switching center, in the microprocessor P. This has the advantage that the corresponding lines are not blocked by unauthorized calls.
Der Mikroprozessor P kann auch interne Änderungen von Telefonnummern vornehmen, indem die richtige Nummer in die Telefonleitung eingegeben wird, obwohl die frühere Tele-15 fonnummer gewählt worden ist. Durch die Speicherung der Telefonnummer des angerufenen Teilnehmers im Gedächtnis des Mikroprozessors P wird zudem ermöglicht, den Anruf zu wiederholen, ohne dass die Telefonnummer neu zusammengestellt werden muss. The microprocessor P can also make internal changes to telephone numbers by entering the correct number on the telephone line, although the previous telephone number has been dialed. Storing the telephone number of the called subscriber in the memory of the microprocessor P also makes it possible to repeat the call without the telephone number having to be put together again.
