Abstract: The invention relates to a distribution device in the subscriber access area, comprising two changeover devices two switching matrices a DSLAM having associated splitter modules and at least one controller. The first changeover device includes m inputs, m first outputs and m second outputs, with a first and a second output having one associated changeover element by means of which an associated input can be selectively connected to the first or to the second output. The second changeover device includes m first inputs, m second inputs and m outputs, with a first input and a second input having one associated changeover element by means of which an associated output can be selectively connected to the first or to the second input. The controller switches the first and second changeover devices and switching matrices.

Abstract: The invention relates to a distribution frame (1) for telecommunications and data technology, the distribution frame (1) having a system side and a subscriber side, which are each formed by at least one distribution frame connection module (2, 3), the distribution frame connection modules (2, 3) each having a jumper side by means of which the electrical connections between the system side and the subscriber side can be changed, comprising an access matrix (15) by means of which the electrical connections are routed between the system side and the subscriber side, the electrical connection being passed on by means of the access matrix (15) or else being connected to a test unit (16) via a test bus (17), the access matrix (15) being arranged in the distribution frame connection module (3, 2) on the subscriber side or the system side, and to a distribution frame connection module (2, 3) suitable for this purpose.

Abstract: The invention relates to a method for etching substrates (4) received in an etching solution (2). Said method comprises the following steps: A basin (1) which can receive the etching solution (2) is prepared, the substrate (4) is completely immersed in the etching solution (2), a flow which surrounds the substrate (4) is produced and the speed and/or direction of the flow can be periodically altered.

Abstract: The present invention is directed to a device for retaining substrates (S), such as wafers or silicon substrates for the production of photovoltaic elements. The device includes opposing walls (1) that are interconnected by at least two rod-like carrier elements (2, 3) that are provided with a retaining means (5) for retaining the substrates (S) in a vertical position oriented parallel to the walls (1). At least one rod-like counter carrier element (4) is also provided and interconnects the two walls (1). The counter carrier element (4) is positioned in relation to the carrier elements (2, 3) so that vertical movement of the substrates (S) relative to the walls (1) is limited and loading or unloading of the substrates (S) is possible at a slant in relation to the vertical direction (V).
