Description
Die Erfindung befaßt sich mit einer Schaltungsanordnung zur Übertragung einer Vielzahl von verschiedenen Steuer- und Berechtigungskennzeichen in Fernmelde-, insbesondere Fernsprechnebenstellenanlagen. The invention is concerned with a circuit arrangement for transmitting a variety of different Control and authorization codes in telecommunications, in particular telephone extension systems.
Bei den bisher verwendeten Schaltungsanordnungen dieser Art wurde die Übertragung von Kriterien für Zwecke der Markierung von Steuerkennzeichen und Berechtigungen durch Stromstufen, durch Stromrichtungen oder durch eine Kombination dieser Möglichkeiten oder/und durch Verwendung mehrerer Adern vorgenommen. Der Aufwand für die Markierung, Übertragung und Auswertung einer größeren Anzahl von Kriterien wurde sehr erheblich.In the previously used circuit arrangements of this type, the transfer of criteria for Purpose of marking tax codes and authorizations by flow levels, by flow directions or by a combination of these possibilities and / and by using several wires performed. The effort involved in marking, transferring and evaluating a large number of criteria became very substantial.
Gemäß der vorliegenden Erfindung werden diese Nachteile der bekannten Anordnungen dadurch vermieden, indem die Steuer- und Berechtigungskennzeichen in einer zentralen Einrichtung in Form von Zeitlageimpulsen erzeugt und über Entkopplungsglieder den Sende- und Empfangsstellen zugeführt werden. Bei einer Verbindung zwischen diesen Stellen werden die Impulse über eine Ader der Verbindungseinrichtung übertragen, und bei jeweiliger zeitlicher Übereinstimmung der angelegten Impulse werten Schaltmittel der Empfangsstelle das bzw. die einer Sendestelle, beispielsweise Teilnehmerstelle, zugeordneten verschiedenen Berechtigungskennzeichen aus.According to the present invention, these disadvantages of the known arrangements are avoided by by storing the tax and authorization codes in a central facility in the form of Generated timing pulses and fed to the transmitting and receiving points via decoupling elements will. In the case of a connection between these points, the pulses are transmitted via a wire of the connection device, and in the case of a respective time Correspondence of the applied pulses is evaluated by switching means of the receiving station or those of the one Sending station, for example subscriber station, assigned different authorization identifiers.
Die Erfindung und weitere Merkmale derselben sind nachstehend an Hand der Zeichnungen näher erläutert.The invention and further features thereof are explained in more detail below with reference to the drawings.
In der Figur ist eine Ausführungsform der Erfindung dargestellt, bei der verschiedene Berechtigungen einer Teilnehmerstelle über eine Verbindungsader d übertragen werden, wobei die Markierung durch zeitlich versetzte Impulse erfolgt. Im Beispiel wird die Markierung individuell, also nicht durch Gruppierung vorgenommen. Als Kennzeichen einer Sendestelle, z. B. Teilnehmerstelle, sind zeitlich versetzte Gleichstromimpulse Jl1 /2 usw .vorgesehen, so daß eine Auswertung in der Empfangsstelle, z. B. LW1 direkt mit Hilfe elektromechanischer Relais Kl1 K 2, Z erfolgen kann. Die genannten Relais sind nämlich einerseits mit der Übertragungsader d verbunden, andererseits ist an diese der zugeordnete Zeitlageimpuls angelegt. Entkopplungsgleichrichter Gl lassen einen zentral angeordneten Impulsgeber zu. Die Auswertung der Kennzeichen kann auch abhängig von der zeitlichen Folge von Schaltvorgängen der jeweiligen Aufbaustufe (z. B. Leitungswähler LW) durchgeführt werden. Kontakte der die Schaltvorgänge bestimmenden Relais schalten dann die entsprechenden zeitlich versetzten Kennzeichen an. Bei Verwendung von Gleichstromkennzeichen weisen die Impulse in der Sende- und Empfangsstelle andere Polarität auf. Um eine schnelle Auswertung zu erreichen, werden zweckmäßig Schaltungsanordnung zur übertragung einer Vielzahl von verschiedenen Steuer-In the figure, an embodiment of the invention is shown in which different authorizations of a subscriber station are transmitted via a connecting wire d , the marking being carried out by time-shifted pulses. In the example, the marking is carried out individually, i.e. not by grouping. As an identifier of a broadcasting station, e.g. B. subscriber station, time-offset DC pulses are Jl 1/2 etc .vorgesehen, so that an evaluation in the reception site z. B. LW 1 can be done directly using electromechanical relays Kl 1 K 2, Z. The said relays are namely connected on the one hand to the transmission wire d , on the other hand the assigned timing pulse is applied to this. Decoupling rectifiers Gl allow a centrally arranged pulse generator. The evaluation of the identification can also be carried out depending on the chronological sequence of switching processes of the respective development level (e.g. line selector LW) . Contacts of the relays determining the switching processes then switch on the corresponding time-shifted indicators. When using direct current indicators, the pulses in the sending and receiving points have a different polarity. In order to achieve a quick evaluation, circuit arrangements for the transmission of a large number of different control

schnell ansprechende Relais verwendet. Über dieselbe Ader d und mit derselben Art von Kennzeichen können auch Rückwärtskriterien, z. B. Melden des Teilnehmers, ausgewertet werden. Beim Melden des Teilnehmers wird durch Kontakte des Schleifenrelais ein Stromkreis gebildet, der das Kennzeichen des Meldens an die ώ-Ader legt. Z-Relais in der Teilnehmerschaltung liegt am selben Impuls und kann infolgedessen ansprechen. Dieses hält sich dann intern weiter.fast-responding relay used. About the same vein d and with the same kind of characteristics can also reverse criteria such. B. reporting the participant, are evaluated. When the participant reports, a circuit is formed by the contacts of the loop relay, which puts the signaling indicator on the ώ-wire. Z relay in the subscriber circuit is on the same pulse and can respond as a result. This then continues internally.
