The invention relates to a wiring arrangement for mixing the outputs of several Subgroups of a feeder group for telecommunications switching systems, in particular a coupler group in telephone systems.

The aim of the invention is to reduce the expenditure incurred for mixing at the installation site of a system to keep the mixing possibilities as small as possible and as large as possible.

The outputs of controlled connecting means of a system, e.g. B. of couplers, selectors or coordinate switches, which are hereinafter referred to as feeders, are with regard to a good utilization of the system to the functional circuits following the feeders, here called consumers, mixed to be connected. The feeders are usually functionally in feeder groups and each tributary group divided into subgroups. The outputs of the subgroups of a feeder group are connected to the recipients assigned to the feeder group in such a way that the To be controlled, in a certain search position of the subgroup reachable customers via an or can be reached via several subgroups in different combinations. This mixing happens by reaching over, staggering and / or interlacing and fulfills the traffic requirements all the more perfectly, the more extensively the aforementioned types of mixture are used and combined with one another can.

In order to achieve such freedom of movement of the mixture, it is known to use the lines of the outputs on the one hand and the customer lines on the other hand to a group of distributors each, which groups face each other in a special frame and their connection points accordingly the desired mixture can be connected to the frame by jumper wires. However, there are long connecting cables from the racks of the feeder and the customer to the shunting rack or there proportionally long jumper wires are required, a relatively large amount of material is required, and the proportion of office installation at the installation site to be used for mixed wiring Plant is given a considerable size.

It is known to reduce this assembly component by connecting the outputs of each subgroup on the frame of the subgroup to two solder lug distributors wired in parallel, which are connected via a movable line, so that a solder lug distributor of one subgroup can be plugged into the other solder lug distributor of the other subgroup wiring arrangement to mix the

can be connected. This wiring arrangement leads to considerable material savings and to simplify assembly at the installation site. However, this is only a connection between Subgroups that follow one another directly after one another are possible, which are referred to as single overlapping is, while a two-person overlap, etc. and an entanglement only by additional jumper wires is possible.

It is also known, in the case of voter frames, the outputs of the voters close together in their frames Bring up lying distributors and mix by bridging the so close together make lying connection points with small electrical bridges. But also here are with Such bridges can only be attacked by one person.

In a wiring arrangement that has already been proposed, all three types of mixing are proportionately short bridges and in a simple way. This is done by having each subgroup a distributor is assigned to which distributor receives several such subgroups Frame are arranged at the same distance from each other and their connection points by prefabricated Connecting cables of the same length can be connected from one distributor to another. But for the entanglement and for two-way reaching over, etc., jumper channels to be occupied by jumper wires are also required intended. Furthermore, it is with the frequently occurring changes in the mix and the set up System necessary to replace the prefabricated connection cables as a whole.

According to the invention, these disadvantages are used as types of such premixed cables, viz by avoiding the outlets of the subgroups the premixing cable 19 for single encroachments, a Vorjean end a connection point, each connection point mixed cable 20 for two-way encroachments and the Voreine Adjacent additional connection point is assigned mixed cable 21 for three-way attacks. The one shown and that some or all of the connection points of a sub-5 feeder group are connected to a pre-wired group with an additional connection point each of an optional connection and additional connection points 7 or 8 at the Bigen other subgroup is delivered to the installation site of the system by means of premixing cables and is entderart there are pre-wired so that the outputs of the partial mixed according to the requirements. These migratory groups in some or in each of the search positions only consists of in suitable places Use different wiring methods with the IO bridges 22 to 25 or 26, whereby these respective auxiliary connection points are connected and bridges 22 to 26 as wires. Solder bridges or stekdass any mixture can be formed by electrical overturns. Because the bridging the pre-wired connection and additional connection points and additional connection points 7 and 8, respectively connecting parts to the respective subgroups are huddled together in a confined space is cash. It is thereby achieved that all these bridges 22 to 26 on the erection 15 are relatively small location of the plant mix to be made dimensions.
