und Rückfragemöglichkeitand inquiry option

Die Erfindung betrifft eine Fernsprechnebenstellenanlage, bei welcher den einzelnen Nebenstellen Zählwerke zugeordnet sind, die eine Erfassung der Gebühren ermöglichen, die die Nebenstellen durch Herstellung von besonders gebührenpflichtigen Amtsverbindungen verursacht haben. Es ist bekannt, den Amtsleitungen Gebührenanzeiger zuzuordnen, die durch tonfrequente Impulse entsprechend der Gebühr einer Verbindung eingestellt werden, welche von dem Amt während der Verbindung auf die Amtsleitung gesendet werden. Zur Einstellung des Zählwerkes einer Nebenstelle, die gerade mit der Amtsleitung verbunden ist, bedarf es einer Weiterleitung der auf der Amtsleitung eintreffenden Impulse zu diesem Zählwerk. Eine Schwierigkeit bei dieser Weitergabe der Zählimpulse bereitet der Umstand, daß die einlaufenden Impulse nicht nur über Wähler weitergeleitet werden müssen, sondern daß sich in der Nebenstellenanlage auch Umschaltestellen in Form von Rückfrageweichen befinden, die während des Gespräches bestimmte Stromwege öffnen und dadurch die Weitergabe der Zählimpulse verhindern. Trotzdem muß die Weiterleitung dieser tonfrequenten Impulse gesichert sein, d. h., die Umschaltestellen im Leitungszug müssen durch besondere, auf die tonfrequenten Impulse abgestimmte Umgehungswege überbrückt werden. Die Erfindung zeigt nun eine Anordnung, wie man in Nebenstellenanlagen über die Amtsleitung einlaufende Gebührenimpulse in einem derThe invention relates to a telephone branch exchange in which the individual branches Counters are assigned that allow a recording of the charges that the extensions caused by the establishment of specially chargeable official connections. It it is known to assign charge indicators to the trunk lines, which are generated accordingly by tone-frequency pulses the charge of a connection, which can be set by the office during the connection sent on the trunk. For setting the counter of an extension that is currently is connected to the exchange line, the incoming calls on the exchange line must be forwarded Impulses to this counter. A difficulty with this transfer of the counting pulses prepares the fact that the incoming impulses are not only passed on through voters must, but that there are also switching points in the private branch exchange in the form of inquiry points that open certain current paths during the call and thereby the transmission prevent the counting pulses. In spite of this, the transmission of these audio-frequency impulses must be ensured be, d. This means that the switching points in the cable run must be based on special, audio-frequency Bypass routes coordinated with impulses can be bridged. The invention now shows an arrangement how to get incoming charge impulses over the exchange line in one of the private branch exchanges

Amtsleitung zugeordneten Summenzähler unabhängig von den einzelnen Sprechstellen erfassen kann und wie trotzdem noch eine individuelle Gebührenerfassung ohne Mitwirkung der Beamtin möglich ist. Dabei ist auf die besonderen Eigenheiten der Nebenstellenanlagen Rücksicht genommen, so daß eine betriebssicher arbeitende Anordnung geschaffen wird, die den Bedürfnissen der Praxis voll und ganz gerecht wird. Erfindungsgemäß wird durch den unter' dem Einfluß der von dem öffentlichen Amt während eines Gesprächs ausgesendeten tonfrequenten Zählimpulses eingestellten Gebührenanzeiger an.der Amtsleitung Impulse aus einer Tonfrequenzquelle der Nebenstellenanlage über die Sprechadern der Nebenstellenvermittlungseinrichtung zu den Anschlußleitungen der mit der Amtsleitung verbundenen Nebenstelle übertragen, und es erfolgt die Anschaltung der Tonfrequenzquelle für die weiterzugebenden Zählstromstöße hin-Record the totalizer assigned to the trunk line independently of the individual microphone units can and how still an individual fee recording without the involvement of the civil servant is possible. The special characteristics of the private branch exchanges are taken into account, so that a reliable working arrangement is created that meets the needs of Practice is fully fair. According to the invention by the under 'the influence of tone-frequency counting pulse sent to the public office during a call Charge indicator on the exchange line pulses from an audio frequency source on the private branch exchange the speech wires of the private branch exchange to the connecting lines of the The extension connected to the trunk is transferred, and the audio frequency source is switched on for the metering current impulses to be passed on

Stromkreise einer Nebenstellenanlage wieder. Die Amtsleitung AL ist durch ein Sperrglied TP abgeriegelt. Vor diesem Sperrglied TP und vor der Umschaltestelle R für Rückfrage liegt ein Gebührenanzeiger GA, welcher die von der Vermittlungsstelle während des Gesprächs übertragenen tonfrequenten Zählimpulse aufnimmt und verarbeitet. Dieser Gebührenanzeiger GA ist mit einem Kontakt ga ausgerüstet, welcher selbst oder unter Zwischenschaltung eines Hilfsrelais einen Tonfrequenzgenerator TG an die Sprechleitungen anschaltet. Der Tonfrequenzgenerator TG kann einen Wechselstrom der Frequenz erzeugen, welche die von der Vermittlungsstelle übertragenen Zählimpulse besitzen. Es kann aber auch eine etwas abweichende Frequenz verwendet werden. Wird beispielsweise für die Übertragung der Zählimpulse von der Vermittlungsstelle zu der Nebenstellenanlage ein Wechselstrom von 16 kHz verwendet, dann kann man zweckmäßig für die Weitergabe von dem Tonfrequenzgenerator TG einen Wechselstrom von 14 oder 18 kHz verwenden. Das Sperrglied TP verhindert eine Einwirkung des von dem Tonfrequenzgenerator TG erzeugten Wechselstromes auf den Empfänger GA. Dieses Sperrglied ist als Tiefpaß ausgebildet und läßt nur die Ströme niedrigerer Frequenz durch.Circuits of a private branch exchange. The exchange line AL is sealed off by a blocking element TP. In front of this blocking element TP and in front of the switchover point R for consultation there is a charge indicator GA which picks up and processes the tone-frequency counting pulses transmitted by the exchange during the call. This charge indicator GA is equipped with a contact ga , which itself or with the interposition of an auxiliary relay connects a tone frequency generator TG to the voice lines. The audio frequency generator TG can generate an alternating current of the frequency which the counting pulses transmitted by the exchange have. However, a slightly different frequency can also be used. If, for example, an alternating current of 16 kHz is used for the transmission of the counting pulses from the exchange to the private branch exchange, then an alternating current of 14 or 18 kHz can expediently be used for the transmission from the audio frequency generator TG. The blocking element TP prevents the alternating current generated by the audio frequency generator TG from acting on the receiver GA. This blocking element is designed as a low-pass filter and only lets through the currents of lower frequency.

Die eigentliche Nebenstellenvermittlung NV istThe actual private branch exchange NV is

in der Zeichnung nur angedeutet, da ihre Ausbildung für die Erfindung ohne Bedeutung ist. An die Anschlußleitungen NL der einzelnen Nebenstellen ist jeweils ein Gesprächszähler GZ über einen Resonanzkreis R angeschlossen, der auf den von dem Tonfrequenzgenerator TG erzeugten Wechselstrom abgestimmt ist. Der Gebührenzähler GZ der jeweils eingeschalteten Nebenstelle wird daher durch die von dem Kontakt ga gesteuerten Impulse betätigt.only indicated in the drawing, since their training is irrelevant for the invention. A call counter GZ is connected to the connection lines NL of the individual extensions via a resonance circuit R , which is tuned to the alternating current generated by the audio frequency generator TG. The charge counter GZ of the respective switched-on extension is therefore actuated by the pulses controlled by the contact ga.
