Description

GERMAN

The subject of the main patent application S 51322 VIII a / 21 a ³ is a circuit arrangement for a switching network that can be used several times, ζ. B. a coordinate selector, in Feranielde-, in particular telephone systems, according to the parallel to the crosspoint rows for connecting a subscriber line to intermediate lines a further crosspoint row is arranged and the contacts of each crosspoint it this row the interconnection of a calling line available intermediate line with the associated cause outgoing connection line.

With coupling fields, where each intermediate line a connecting line is permanently assigned, is by the arrangement according to the main patent application the expense of special through-switch relays for switching through an intermediate line an outgoing connection line avoided.

The object of the invention is to create an arrangement in which the at the coupling points to the to connect a calling line to an intermediate line serving parallel crosspoint rows Coupling contacts provided for coupling point row are used particularly expediently. Achieved this is achieved by the fact that the interconnection is made available to a calling line Intermediate line with an outgoing connecting line causing contacts directly in front of one the: number of intermediate lines to another! Number of connecting lines to be converted Multiple field are arranged.

Due to the coupling contacts arranged directly in front of the multiple field, with coupling fields double-directional intermediate lines an internal blocking of the switching network over the multiple field avoided. When connecting an intermediate line to your connecting line by pressing the Coupling contacts secure the non-actuated coupling contacts of every other intermediate line that can be coupled with the same connecting line, their occupancy in the incoming direction. The coupling contacts themselves do not make a route selection and therefore only serve the coupling or the decoupling.

In the drawing, an embodiment of the invention is shown in schematic form. Shown are the first and the last of ten large subscriber switching groups TKpGrI and TKpGrO, which, for example: are provided for 100 subscribers, of which 20 are again assigned to a subscriber coupler (TKp).

For such a subgroup of 20 subscribers, ten intermediate lines ZL 1/11 to ZL 0/11 can be reached via the subscriber coupler TKpIl.

serve both outbound and inbound.

In the outgoing direction, the Zwischenleitumgeo, eg the intermediate lines ZL1 / 11 and ZLO / 11, are connected via coupling contacts k 1/11 and feO / 11 to the connecting lines VLx, VLy leading to the first group selector. Between the, coupling contacts & l / llj. . . and the connecting lines, however, are arranged in a multiple field V , via which the number (500) of outputs from all large subscriber switching groups TKpGrI to TKpGrO is reduced to, for example, a lower number of outgoing connecting lines.

The incoming traffic is fed to the selector couplers WK pi to WKpO via the connecting lines VLa, VLb . The number of incoming connecting lines VLa, VLb can be chosen arbitrarily; it is indicated with "x" on the selector coupler WKp 1 or WKpO. Each selector coupler (WKp) is intended for a large subscriber coupling group (TKpGr) and accordingly has 50 outputs to which the 50 intermediate lines of the large group: are connected.

If a subscriber connected to the subscriber coupler TKpll now wishes to establish a connection, one of the via

intermediate lines that can be reached by this subscriber coupler, for example the intermediate line ZL0 / 11, are made available. A connection between this intermediate line and the connecting line VLx connected to the multiple field V and thus to the first selector stage is switched through via the coupling contact k 0/11. The still open contacts in the remaining intermediate lines arranged in the outgoing direction in front of the multiple field now ensure that the outputs from different subscriber couplers combined in the multiple field remain free for the incoming traffic produced via the selector coupler (WKp). The coupling contacts arranged directly in front of the multiple field thus serve not only to switch through the intermediate line to the connecting lines, but also to decouple the intermediate lines from one another.
