Anordnung für Fernsprechanlagen mit gemeinsamer Leitung für mehrere Teilnehmer.
Die Erfindung bezieht sich auf eine Signalanordnung für Telephonanlagen, bei welchen einer Anzahl von Telephonapparaten eine gemeinsame Leitung zur Verfügung steht, wobei im Falle des Besetztseins der Leitung in sämtlichen Telephonapparaten ein Besetztzeichen erscheint.
Derartige Telepbonsysteme sind insbesondere dort üblich, wo eine Anzahl Nebenstellen an eine Amtsleitung angeschlossen sind. Bei derartigen Anlagen ergibt sich jedoch der Nachteil. dass

Arrangement for telephone systems with a common line for several participants.
The invention relates to a signal arrangement for telephone systems in which a number of telephone sets are available on a common line, with a busy signal appearing in all of the telephone sets when the line is busy.
Such telephony systems are particularly common where a number of extensions are connected to an exchange line. In such systems, however, there is the disadvantage. that

a line, for example a post line, on all telephones with the exception of those who keep the post line occupied, the office key or the mtsoben'l is sunk into the box.
With this arrangement, a special indicator is not required because the exchange key or the lever in the event of occupancy (learning of the subscriber's hand area is full

where as before the connection, for example to the post office line, by pressing the
Button. The button a takes a disk c down with it. The disc c in turn presses on a pin d which moves the switch in a known manner. The changeover switch @ is not shown since it has no connection with the present invention.
In the event that the post line is occupied, the electromagnet in the so-called signal line is erect and the armature f is attracted. The way the signal
