Description

Für den Gegensprechverkehr mittels gerichteter ultrahochfrequenter Wellen zwischen zwei Stationen besitzt jede der Stationen eine Sende- und eine Empfangsanlage, die räumlieh so aufgestellt sind, daß gegenseitige Kopplungen möglichst vermieden sind.For two-way communication using directed ultra-high frequency waves between two stations, each of the stations has a transmitting and a receiving system, the spatial are set up in such a way that mutual couplings are avoided as far as possible.

Derartige Stationen können durch an sich bekannte Mittel so ausgestattet werden, daß sie Gespräche auch in unbesetztem Zustande aufnehmen können. Beispielsweise kann der Empfänger auf einen Magnettonschreiber arbeiten, der zweckmäßig durch einen Schaltwechselstrom durch den Sender der Gebestation betriebsbereit gemacht wird. Bei derartigen oder ähnlichen Anlagen will man wissen, ob der bediejiungslose Empfänger die Nachricht auch wirklich aufnimmt, also störungsfrei arbeitet.Such stations can be equipped by means known per se so that they can take up calls even when they are unoccupied. For example, the Receiver work on a magnetic recorder, which is expediently through a switching alternating current is made ready for operation by the transmitter of the transmitter station. With such or similar systems you want know whether the unattended recipient is actually recording the message, i.e. without interference is working.

Erfindungsgemäß wird eine Kontrolle der Empfangsbereitschaft der angerufenen Station B durch die anrufende Station A dadurch ■ vorgenommen, daß der Empfänger der Station B an den Sender der gleichen Station angeschlossen wird, so daß eine durchgehende Verbindung Sender A—Empfänger B— Sender B— Empfänger^ entsteht. Die Inbetriebsetzung des Senders in der angerufenen Station durch die anrufende Station ist bereits bekannt. Die nach Inbetriebsetzung des Senders der Gegen-Station gemäß der Erfindung aufzubauende Durchrufschaltung kann sich sämtlicher, für Fernschaltungen bekannten Mittel, Schaltstöße, Modulationsfrequenzen ti. dgl. bedienen, die es ermöglichen, Relaisanordnungen in Tätigkeit zu setzen, die ihrerseits die in der angerufenen Station gewünschten Schaltvorgänge auslösen. Nach Inbetriebsetzen der Geigenstation kann dann das in der Station A aufgegebene Gespräch im Empfänger dieser Station wieder aufgenommen und dabei festgestellt werden, ob die Stationen in Ordnung sind. Die Station A wird in der gleichen Weise ausgebildet wie die Station B, so daß auch die Station A von der Station B aus auf Betriebsbereitschaft geprüft werden kann, bevor ein Gespräch von B nach A durchgegeben werden soll. Zur Aufnahme der Gespräche können beispielsweise Magnettongeräte verwendet werden, die ebenfalls durch Fernschaltung in Betrieb gesetzt und nach Übertragung des Gespräches wieder abgeschaltet werden können. Um die Schaltvorgänge jederzeit durchführen zu können, müssen die Empfänger natürlich eingeschaltet bleiben.According to the invention, the readiness to receive of the called station B is checked by the calling station A in that the receiver of station B is connected to the transmitter of the same station, so that a continuous connection between transmitter A - receiver B - transmitter B - receiver ^ arises. The commissioning of the transmitter in the called station by the calling station is already known. The paging circuit to be set up according to the invention after the transmitter of the opposite station has been put into operation can use all means known for remote switching, switching surges, modulation frequencies ti. Like. Operate, which make it possible to set relay arrangements in action, which in turn trigger the switching operations desired in the called station. After the violin station has been put into operation, the call abandoned in station A can be resumed in the recipient of this station and it can be determined whether the stations are in order. Station A is designed in the same way as station B, so that station A can also be checked for operational readiness from station B before a call is to be passed from B to A. Magnetic sound devices, for example, can be used to record the calls, which can also be activated remotely and switched off again after the call has been transmitted. In order to be able to carry out the switching processes at any time, the receivers must of course remain switched on.
