Description
Schaltungsanordnung für Mitläufer in Selbstanschlußfernsprechanlagen Die Erfindung betrifft eine Schaltungsanordnung für Mitläufer in Sel:bstanschl@ußfernsprech:anlagen. Bekanntlich werden Mitläufer zu den verschiedensten Zwecken in Selbstanschlußfernsprechanlagen benötigt.Circuit arrangement for followers in self-connecting telephone systems The invention relates to a circuit arrangement for followers in Sel: bstanschl @ ußfernsprech: systems. It is well known that followers are used for a wide variety of purposes in self-connecting telephone systems needed.
Derartige Mitläufer-d. h. durch dieW.ahlimpulse gleichzeitig mit den Wählern der rernsprechverbindung verstellte Wähler -werden beispielsweise angewendet bei der Gebührenkontrolle von Münzfernsprechern im Netzgruppenverkehr oder zur Sperrung bestimmter Verbindungen von Sprechstellen mit beschränkter Verkehrsmöglichkeit.Such followers-d. H. through the dialing pulses simultaneously with the Voters that have been banned from the telephone connection are used, for example for the charge control of payphones in network group traffic or for blocking certain connections from microphone units with restricted traffic.
Der Mitlä,uferwähler wird durch ein Impulsrelais gesteuert, das in einem vor den Wählern angeordneten Übertrager untergebracht ist.The follower selector is controlled by a pulse relay that is in a transformer arranged in front of the voters is housed.
Bei der bekannten Schaltung ist das Impulsrelais des Mitläufers pgrallel zum Steuerrelais des Gruppenwählers geschaltet und durch einen in die Leitung geschalteten Kondensator vom Steuerrelais des Gruppenwählers getrennt. Aus Symmetriegründen muß auch in der zweiten Sprechader ein Abriegelungskonden:sator - :mit entsprechenden Ausgleichsdrosseln vorgesehen werden.In the known circuit, the impulse relay of the follower is parallel switched to the control relay of the group selector and switched into the line by one Capacitor separated from the control relay of the group selector. For reasons of symmetry must also a blocking capacitor in the second voice vein: sator -: with corresponding Compensating chokes are provided.
Bei der Gebührenkontrolle von Münzfernsprechern müssen neben der Wahlimpulsgabe auch noch Geldimpulse über die Leitung gegeben werden. Durch die Anschaltung der Geldimpulsrelais an die Leitung läßt sich die Symmetrier:ung der Leitung nicht befriedigend durchführen, so daß Impulsverzerrungen eintreten.In addition to dialing impulses, when checking the rates of payphones even money impulses can be given over the line. By connecting the The balancing of the line can not be achieved satisfactorily perform so that impulse distortion occurs.
Durch die Erfindung wird eine Ersparnis an Schaltmitteln durch Vermeidung der Ab- riegelungskondensatoren und der Ausgleichsdrosseln erzielt und die Wahlimpulsgabe verbessert. , Erreicht werden diese Vorteile dadurch, daß durch den ersten Impuls jeder Wahlstrom.stoßreib.e das mit dem Impulsrelais des Gruppenwählers in Reihe geschaltete Impulsrelais des Mitläufers ein während derWahl erregtes Hilfsrelais zumAnsprechen bringt, daß die weiteren Impulse jeder Wa.hlstromstoßreihe über das Impulsrelais des Mitläufers in einem von dem Impulsrelais des Gruppenwählers abgetrennten Stromkreis verlaufen und daß ;dabei das Impulsrelais des Mitläufers das Impulsrelais des Gruppenwählers steuert.By the invention, a savings of switching means is Reset of capacitors by avoidance of waste and the achieved balancing chokes and improves the dial pulsing. These advantages are achieved by the fact that the impulse relay of the follower connected in series with the impulse relay of the group selector causes an auxiliary relay that is energized during the election to respond with the first impulse of each impulse current series via the impulse relay of the Follower run in a circuit separated from the impulse relay of the group selector and that the impulse relay of the follower controls the impulse relay of the group selector.
In der dargestellten Schaltung ist mit.-1\ r. eine Sprechstelle bezeichnet, von der aus in.@ bekannter Weise die Wähler des Amtes durch Schleifenunterbrechungen beim Ablauf der Nummernscheibe :eingestellt werden. Beim Abheben des Hörers wird in bekannter Weise der erste Vorwähler L VW in Gang gesetzt, der einen freien ersten Gruppenwähler L G1V belegt. Das Relais A und das Relais J sprechen über den Schleifenstrom an. Das Relais J besitzt zwei Wicklungen J I und 111, von denen die Wicklung J I durch den Kondensator K während des Gesprächszustandes überbrückt ist. Über Kontakt 2i wird das abfallverzögerte Relais C erregt. Beim Aussenden einer Wählstromstoßreihe fallen bei der ersten Schleifenunterbrechung das Relais J und das Relais A ab, so daß über den Kontakt 2i der Drehmagnet D des Mitläufers, dessen Kontaktarme mit D I und D II bezeichnet sind, den ersten Impuls erhält. Gleichzeitig zieht über die Kontakte i i und i c das abfallverzögerte Relais L' an. Durch den Kontakt 2v, der als Schleppkontakt ausgebildet ist; wird die Leitung zwischen dein Relais J und dem Relais A getrennt und die Wicklung J II in Reihe mit der Wicklung J I geschaltet. Die weiteren Wahlstromstöße der ";ausgesendeten Stromstoßreihe für das Re-Jais A verlaufen in nachstehendem- Stromkreis Erde; i i, 3 v, Widerstand Wi, A, Batterie. Nach Beendigung einer Stromstoßreihe fällt das Relais V ab, und die beschriebenen Schaltvorgänge wiederholen sich bei der nächsten Stromstoßreihe.In the circuit shown, with-1 \ r. denotes a call station from which, in a known manner, the voters of the office are set by loop interruptions when the dial is running. When the receiver is picked up, the first preselector L VW is set in motion in a known manner, which occupies a free first group selector L G1V. Relay A and relay J respond via the loop current. The relay J has two windings JI and from which the winding JI is bridged by the capacitor K during call state 1. 11 The release-delayed relay C is energized via contact 2i. When a series of dialing currents is sent, the relay J and relay A drop out at the first loop interruption, so that the rotary magnet D of the follower, whose contact arms are labeled DI and D II, receives the first pulse via contact 2i. At the same time, the release-delayed relay L 'picks up via contacts ii and ic. Through the contact 2v, which is designed as a drag contact; the line between relay J and relay A is disconnected and winding J II is connected in series with winding JI. The further optional current impulses of the "; transmitted current impulse series for the Re-Jais A run in the following circuit earth; i i, 3 v, resistance Wi, A, battery. After the end of a current impulse series, the relay V drops out and the switching operations described are repeated at the next series of impulses.
