PATENTAMT.PATENT OFFICE.

Die Erfindung hat einige Verbesserungen und weitere Ausbildungen der durch Patent 268247 geschützten Schaltung zum Gegenstand.The invention has several improvements and further developments of that disclosed in patent 268247 protected circuit to the subject.

Bei den Nebenstellenanlagen, bei denen jede Sprechstelle sich selbst mit der Amtsleitung verbinden kann, werden bekanntlich die Besetztzeichen, welche die Benutzung einer Amtsleitung den anderen Sprechstellen anzeigen sollen, derart zur Wirkung gebracht, daß zu gleicher Zeit auch die Überwachungszeichen auf dem Fernsprechamt zum Anzeigen des Gesprächszustandes gesteuert werden. Zur Vereinfachung der Leitungsführung wurde zur Vornahme der erforderlichen UmschaltungenIn the case of private branch exchanges, in which each microphone unit connects itself to the exchange line can connect, the busy signals are known, which indicate the use of an exchange line to the other microphone units should, brought into effect in such a way that at the same time the monitoring signals can be controlled on the telephone exchange to display the status of the call. For simplification the routing was used to make the necessary switchovers

J-5 an der Amtsleitung ein Relais vorgesehen, welches in den Stromkreis der Besetztzeichen geschaltet und gleichzeitig mit . diesem eingeschaltet wurde. Infolgedessen konnten sowohl die Besetztzeichen als auch die Amts-Überwachungszeichen von demselben Schalter der Sprechstelle gesteuert werden.J-5 a relay is provided on the trunk line, which is switched into the circuit of the busy signal and at the same time with. this turned on became. As a result, both the busy signals and the official monitoring signals could be used can be controlled from the same switch on the call station.

Die vorliegende Erfindung betrifft eine Schaltungsanordnung, bei der die Signalgabe zum Amt anders geregelt wird als in der Neben-Stellenanlage. Zur Signalgabe für die Neben-· stellen untereinander sind nämlich zwei Arten von Schauzeichen vorgesehen, von denen das eine anzeigen soll, daß auf der Amtsleitung ein Gespräch geführt wird, das andere, daß eine Sprechstelle sich auf Rückfrage geschaltet hat. Die Erfindung besteht nun in einer zweckmäßigen Vereinigung dieser beiden Signalstromkreise mit dem die Amtsüberwachungszeichen steuernden Relais, so daß dieses mit beiden Schauzeichengruppen zusammenarbeitet, damit ein Wechsel in der Verbindung von Amt auf Haus auf die Amtsüberwachungszeichen ohne Einfluß vor sich gehen kann.The present invention relates to a circuit arrangement in which the signaling for Office is regulated differently than in the private branch exchange. For signaling the secondary two types of indicators are provided one below the other, one of which is the one should indicate that a call is being made on the outside line, the other that one Call station has switched to inquiry. The invention now consists in an expedient one Combination of these two signal circuits with the relay controlling the office surveillance signals, so that this with both Indicator groups work together to allow a change in the connection from office to House can go on without affecting the official surveillance signs.

Auf der Zeichnung ist die neue Schaltungsanordnung in einem Ausführungsbeispiel sehematisch veranschaulicht. Diese entspricht im wesentlichen den Schaltungen des Hauptpatents (insbesondere Fig. 2), nur ist hier noch eine neue Art der Stromführung für die Rückfrageschauzeichen zur Anwendung gekommen. Die Rückfrageschauzeichen sind nämlich erfindungsgemäß von den Postschaltern aller Sprechstellen derart abhängig gemacht, daß die von einer in Rückfrage befindlichen Sprechstelle eingeschalteten Rückfragezeichen von einer anderen Sprechstelle, welche die Anitsleitung von der ersteren übernimmt, zurückgeschaltet werden können, zu dem Zweck, die Übernahme der Postleitung nicht allein durch das Wiedererscheinen der Postschauzeichen, sondern noch durch das Zurückgehen der Rückfrageschauzeichen kenntlich zu machen. Der Vorteil dieser neuen Anordnung liegt einmal in der doppelten Signalgabe, die das Erkennen der Schaltvorgänge erleichtert und Störungen leichter kenntlich macht, sodanri auch läßt sich nunmehr eine wesentlich einfachere Vereinigung der beiden Schauzeichen zu einem einzigen durchführen, die eine sichere Signalgabe nach der einen oder anderen Art gewährleistet.In the drawing, the new circuit arrangement is shown schematically in one embodiment illustrated. This corresponds essentially to the circuits of the main patent (In particular Fig. 2), only here is a new type of current management for the query indicator came into use. According to the invention, the inquiry indicators are from everyone's post office counters Call stations made so dependent that the call station in question switched on inquiry signal from another intercom, which the anitsleitung from the former takes over, can be switched back, for the purpose of not taking over the post line alone the reappearance of the postal indicators, but also due to the receding of the inquiry indicators to be identified. The advantage of this new arrangement lies in the double signaling that the detection which facilitates switching operations and makes faults easier to identify, sodanri can also be used now a much simpler combination of the two indicators into a single one perform that ensures a reliable signaling of one type or another.

Claims

Circuit diagram is the specified inventive idea by using a possible a small number of lines and switch springs. In place for everyone to run a special battery cable for the indicator groups to all post office counters, is according to the invention the battery line for the two indicator groups via interruption contacts all post office counters led

ίο and the switching line for the inquiry characters branched off behind the last of these contacts. The circuit diagram contains two call stations I and II, their speech sets 5 by means of the post office counter 1 connection with the Exchange line 15 can receive, with the house lines connected at 7 in an are switched off in a known manner. In connection with the post office counter 1 is the Secondary switch 2, which maintains the switchover for the inquiry. The postal call indicators are denoted by 3 and 4 and the busy signals that are switched on for the inquiry are denoted by 9 and 10. To excitement A battery 11 is provided for the indicators.

From this, a connecting line 12 leads in series via interruption contacts 16 to the post office counters i, and from the last of these contacts is, as indicated by a loop 13, connection with a Switching line 18 produced. From this switching line switch contacts 17 are branched off, the in the working position of the secondary switch 2 connection with a supply line 8 for the inquiry indicator 9, 10. In the working position of a post office counter 1, the Connecting line at contact 16

"is broken and thus the connection with the switching line 18 is canceled. At the same time but a contact 19 is closed, whereby a feed line 6 for the postal indicator 3, 4 with . the battery line 12 connection receives. To the Control of the office monitoring signs, not shown, is - an office with central battery operation provided - a choke coil 14 is provided, which during use the trunk line 15 is switched in a bridge to the speech wires. For the purpose a relay 20 is provided which, with its contact 21, closes the throttle bridge 14 causes. Appropriate switchovers are required for offices with different signaling to be provided by the relay 20. The relay 20 is connected to the circuit ^ of both indicator groups 3, 4 and 9, 10 in connection, so that if from a call station, for example, the Postal indicators 3, 4 are switched on, the relay 20 is energized, and if on it to The purpose of the query is the usual switchover, with the postal indicator 3, 4 are switched off and the inquiry characters 9, 10 are switched on, the relay 20 constantly ■ remains excited. This leaves the trunk monitoring characters from changing the connection unaffected and interference in the signaling is avoided. The same is the case when the change in connection when taking the outside line from soaps takes place at another call station. For example, if the station I is in the Inquiry status to cause microphone unit II to take over the exchange line 15, then the following circuit is established: from battery 11 via line 12 and the result the inquiry again closed Kontalct 16 at the post office counter 1 of the point I, then via the Contact 16 of the call station II, loop 13, line, which is still in the rest position 18, then via the contact 17 of the closed as a result of the inquiry in the working position Place I, line 8, inquiry flags 9, 10 and relay 20 back to battery 11. Switches Intercom station II now calls in to take over the exchange line, then interrupts it at their post office counter 1 the contact 16, whereby the switching line 18 of the inquiry characters 9, 10 separated from the battery line 12 will, - As a result, the inquiry characters arise back, and at the same time the postal indicators 3, 4 appear, because over the contact 19 the following circuit is closed: from Battery 11, line 12, contact 16 at point I, Contact 19 at position II, feed line 6 and postal indicator 3, 4, as well as the winding of the relay 20 back to battery 11. The disappearance of the inquiry mark 10 and reappearance of the postal indicator 4 recognizes the point I that the point II the trunk line 15 properly take over. Since the relay 20 remains energized when the indicator groups change, there is signaling to the telephone exchange does not take place, so that the connection remains there. Only when all microphone units have switched to their rest position and no indicator group is excited, the relay 20 is also de-energized. As a result, the bridge 14 is switched off, whereupon the office receives the final signal. Here, too, the postal call signs 3 and .4 can be used as a locking electromagnet for the post office counter form.
