Abstract

1. Circuit arrangement for receiving data signals which occur at a relatively high speed on high-speed incoming lines (NKan1-NKanx) and forwarding these data signals via high-speed outgoing lines (NKb1-NKabx) in a data switching network which includes at least one t.d.m. data switching system (EDS) and in which each t.d.m. data switching system (EDS) is assigned a separate switching device (K) via which the aforementioned data signals are switched and which for this purpose can be controlled by a control device (UEAS) of the t.d.m. data switching system (EDS) which serves to switch items of signalling information which occur at a relatively low speed in the course of the respective data signal connection, characterised in that the switching device (K) is provided with a switch-through store (DS) with incoming cells (Zz) which are individually assigned to the high-speed incoming lines (NKan1 to NKanx) and into each of which an address of a high-speed outgoing line (e.g. NKab1) to be used for acceptance of data signals can be input by the control device (UEAS) of the associated t.d.m. data switching system (EDS), and that in the course of the switching of data signals which occur at the high speed, only that incoming cell (Zz) within the switch-through store (DS) which is assigned to the relevant high-speed incoming line (e.g. NKan1) is operated, and by making available the address (ADR) contained in the incoming cell (Zz) in question the high-speed outgoing line (NKan1) to be used for acceptance of data signals is actuated.
