Zusatz zum Patent 967314Addendum to patent 967314

In dem Hauptpatent 967314 ist eine Vorrichtung zum Sperren mehrstelliger Sperrnummern an den Selbstwählern von Münzfernsprechern beschrieben, die sich durch eine besonders vorteilhafte, gedrängte Bauweise auszeichnet und außerdem ermöglicht, zwei oder mehr vollständige Nummern unabhängig voneinander zu sperren, d. h. also so, daß die Nummern, die durch Austausch in dierselben Dezimalstelle liegender Ziffern dieser Sperrnummern gebildet werden können., nicht unbeabsichtigt mitgesperrt werden.In the main patent 967314 is a device to block multi-digit blocked numbers to the Self-dialers of payphones described, which are through a particularly advantageous, crowded Design distinguishes itself and also allows two or more complete numbers independently to block from each other, d. H. so that the numbers that are replaced by the same decimal place lying digits of these blocked numbers can be formed., not unintentionally blocked will.

Es hat sich gezeigt, daß diese Sperrvorrichtung nicht nur zur Verwendung in Münzfernsprechern geeignet ist, sondern auch — wie die früher bekannten Sperrvorrichtungen — mit Vorteil in allen mit Nummernschaltern ausgerüsteten Fernsprechapparaten verwendet werden kann, wenn das Anwählen bestimmter Nummern oder Nummerngruppen verhindert werden, z.B. einzelnen Nebenstellenanlagen die Wahl des Amtes oder des Fernamtes usw. unmöglich gemacht werden soll. Für solche Zwecke hat man bisher in die Amtsleitungen Sperrmitlaufwerke gelegt, die nur von den berechtigten Teilnehmern außer Wirkung gesetzt werden konnten. Ist die Zahl der nichtberechtigten Nebenstellenteilnehmer nicht allzu groß und stehen insbesondere der Nebenstellenzentrale mehrere Amtsleitungen zur Verfügung, so gestaltet sich der EinbauIt has been shown that this locking device is not only for use in payphones is suitable, but also - like the previously known locking devices - with advantage in all telephone sets equipped with number switches can be used when dialing certain numbers or number groups can be prevented, e.g. individual PBXs the choice of office or remote office etc. is to be made impossible. For such Purposes have hitherto been placed in the trunk lines blocking follow-up drives, which are only used by the authorized Participants could be overridden. Is the number of unauthorized extension users not too big and there are several trunk lines especially at the branch exchange is available, this is how the installation works

809 614/5809 614/5

von Sperrvorrichtungen gemäß dem Hauptpatent in die Fernsprechapparate der nichtberechtigten Nebenstellen wesentlich billiger als der Einbau der kostspieligen Sperrmitlaufwerke in die Amtsleitungen. of locking devices according to the main patent in the telephones of the unauthorized Extensions are much cheaper than installing the expensive locking followers in the trunk lines.
