The present invention relates to a registration switching system, in particular a telephone ao example of its execution, which is limited to the components necessary for understanding the circuit arrangement for markable telephones of the invention.
Switching systems, with individual connections consisting of remote connection systems, such as those in the "Siemenssen and with these individually assigned journal", 1964, issue 4, pp. 246 to 248, are used in the following description. which are written when selecting the respective, as known to the reader, assuming the hunt group via an individual marking input circuit can be marked and set by a central control device,
In the figure, a selection device A is now to be selected for a single line and for through a hunt group with a maximum of eight individual connections of the desired connection via one line. The selection device is connected to the selected individual connection 30 with a central control device Z in V ^ bin marking circuit, with the one input circuit ME , which is essentially subject to a given assignment sequence, when the individual connections are selected individually relay (Chain relay) assigned hunt group receives a mark, which are net with the help of a chain of their contacts. In addition, the selection device A is available with the assignment 35 of the individual connections of this hunt group to the next individual connection after the assignment of an individual connection, for which the assigned subscriber circuits TA 7, TA 29 ... contacts of these chain relays to an individual power ring input circuit of the hunt group that is assigned to the marker and TA 67.

The object of the invention is to mark the hunt group with the help of marked adjustable telecommunications switching system of the contact 2 s. About the rest spring with simple means for a collective connection 50 of the contact 4 si 1, the marking circuit M 1 and incoming calls evenly to the individual connection to the marking wiring M ^ is to distribute the individual connection. This task is marked on a TA 7. With the help of the central circuit arrangement, not shown, of the aforementioned type len setting device, a connection is made between the fact that, in order to achieve an equal to the dialing subscriber and the individual distribution of the incoming calls to the 55 connection TA 7. This occupies the occupancy row connection TA 7, which ensures individual connections. If the connection is carried out after a single connection has become free, the central control device, like the one assigned to it, is activated after this single connection has been assigned, whereupon the assignment of the next single connection relay S , among other things, is released again. Via contact 3 s this preparatory, energized chain relay is energized until it is reached. The relay ST 1 is now energized Earth, which in each case prepare the next hold circuit, remains energized, connection TA 7 to the test and occupancy wire and this chain relay is switched depending on one. The relay STl responds. Via its common contacts 1 si 1 and 2 si 1, which are dependent on the contacts of all chain relays, it only then forms a holding current relay in its original circuit, which returns via the common contact 1 de understood (e.g. idle state) and thus which runs. In addition, the contact 4 si 1 is actuated, which means that the first individual connection is occupied by the contacts 4 st 1 to 4 st 8.

If, for example, the individual connection TA 67 has been occupied once, the relay DC is disconnected and then also free again, the rejection remains because all contacts 3 si 1 to 3 si 8 on relay STH are no longer excited because it is over who are divided. Then, from the relays ST 1 to see the contacts 2 si 8 and 2 si 2 lying still ST 8, all those whose corresponding, non-closed holding contacts cannot form a holding circuit combined to form the collective connection.
