The invention relates to a circuit, the coupling paths of the system, the subscriber circuit arrangement for private branch telephony systems with a free cross-connection line transmission be-cross-connection traffic between the different places. In the other embodiment, two crosspoints of the coupler cross connection lines can be operated in the system via cross connection lines and the through coupler in order to transfer the inquiry line with a gene, as well as with office traffic in each system via free access to a cross connection line over exchange lines and the transmission assigned to the exchange lines within the one coupling stage to connect office transmissions, in the case of inquiry connections. In the first-mentioned embodiment, crosspoints in the subscriber switching network are established during existing exchange connections from one subscriber or each system per cross-connection line transmission, also via cross-connection circuits. and corresponding control and marking devices are necessary for a large number of known circuit arrangement. In the second embodiment, openings such. B. in the case of the German patent specification, the central control device must have the option 1146 136 described telephone extension, In the through coupler two crosspoints system, inquiry connections are to be controlled in the exchange and to make the corresponding return via a corresponding inquiry switch in dialing processes. Also, pro must have made the transfer of office. Via this inquiry / inquiry set and for each cross-connection line transfer switch, corresponding crosspoints will be available after the inquiry identification has been issued, i.e. after reversing the switch a to which a subscriber circuit is assigned, has the option of accessing the switching network via cross-connection lines for establishing the within reach subscriber stations and, in particular, also system inquiry connections. From this particular cross-connection lines of different cross-their subscriber circuits, cross-connection line bundles can also be reduced and, for this purpose, connection lines and other access lines to create a clear circuit arrangement. With these inquiry connections this is achieved by the fact that a cross connection is not on special; j, it is provided of residues dungskoppler the manufacture, inhibited when all Ouerverfrageverbindungen to the office, it would connecting line transmissions and all but Teilneheine Official inquiry readily possible. In these known A! Orders without 30 inquiry sets, there are switched cross-connection lines in such a way that every cross-extension has the option of making inquiry connections from one bundle of connecting lines to every other bundle of connecting lines to another bundle of connecting lines , trunk line consultation transmission with everyone because consultation sets are switched as a subscriber circuit, cross connection line transmission over two cones. 35 pel points per connecting wire to be transmitted

Furthermore, there is a circuit arrangement by means of which it can be interconnected in the cross-connection coupler. German Offenlegungsschrift I 537 876 known, in this way it is possible in a simple manner with the connection from a trunk bundle of a small number of cross-connecting lines to another trunk group consultation sets, which are connected as a subscriber circuit can be established that the latter are 40, via the special cross-connection coupler mentioned Establishing trunk group as a subscriber consultation call. There are in merschaltung-switched transmissions assigned to this coupler as many coupling points for the rear, of those asking about the choice of the direction code necessary as such inquiry sentences and one can be occupied by means of free choice. Necessary on these interconnection line transmissions This can then be a through connection. When expanding the system with cross-earthing through a private branch exchange to another trunk transmissions, the number remains Ancillary to cross-connection line feedback records and delivery system that can be reached via cross-connection lines getting produced. ordered crosspoints unchanged.

Communication transmissions are also made according to the selection of the cross-connection digits in the QDR cross-connection coupler by reversing over the two crosspoints, namely A, B, C, D stages are occupied. these crosspoints in a row or column in the embodiment shown in the helmet are each arranged in a known manner. There are so many cross-link transmissions in total, e.g. B. QUeI and QUeI, coupling contacts for a through -connection, shown as two cross-connecting line bundles QVL1 and circuit cores between the consultation set and the QVL 2. Are to be switched through via the Querverbindunqskoppier cross connection transmission. QDR can cross-connection transmissions for the establishment of connections between cross-connection line bundles or if 30 see cross-connection transmissions different this is not particularly prevented, the cross-connection line transmissions of the same bundle are also established between licher bundles. The Q-SU transmission searcher for the incoming connections between cross-connection transmissions and unoccupied cross-connection line transmissions in the same bundle must, however, be useful. For the purpose of evaluating the selected code number in the outgoing exchange on the basis of 35, a * i of the cross-connection core number dialing will also be prevented in this case by means of blocking. Transmission line transmission a free memory R an-It can therefore be the traffic over the cross-connected, which recognizes whether the connection to a connection coupler is only a real Durchgangsver- extension subscriber of the selected system or wrong. In order to now select a system that can be reached via another cross-connecting trunk group inquiry connection during an existing exchange via this coupler. If a connection is to be established, cross-connection other cross-connection line bundles are selected, dungsleitur.gsrückfragesätze RG are provided, which are connected as so in the cross-connection coupler QDR even participants on the coupling network. if there are two crosspoints in a row or column In the present case, the cross-connection for the connection to one of the line consultation set RG via the number of contacts corresponding to the number of contacts RA and the coupling stages A, B, C, D is to be controlled with the . Connection set VS connected. Of course, it is evident from the provision that the cross-connection could also be connected to this subscriber circuit with the connection coupler if it was already connected to the connection between cross-connections for the Hcr exchange transmission via the switching stages. In the exemplary embodiment, 50 line transmissions of different cross-references are only based on a specific system. The connection set VS can be switched via the coupler VK chendc assignment of cross connection lines with house transfers or office transfers in addition to the inquiry traffic to cross connection groups, namely in this connection set: n different cross connection line set switching means for the said transmission bundles arranged together without additional expenditure on evaluation means. That way can take in can. known way the circuit effort in the line The connections to internal participants of the transmission, for example incoming or outgoing to cross-connection wear and tear, can be reduced to a minimum.
