Summary:In a data transmission system, a switching network in a connection node (VK) includes switch groups (SCH) for switching channels, which are each assigned to one or more time slots within the framework of a multiplex time signal, e.g. virtual containers of a STM-1 frame according to CCITT recommendations G707 to G.709. Each switch group (SCH) is modular and linked to one another, and contains a memory (DS) with several independently readable memory outputs (SA1 to SA4), through which the storage area can be accessed. Each part signal of a respective memory address can be connected with a data output of the switch group (SCH) through selectors (SEL1 to SEL4). A connecting memory (VB1 to VB4) controls the reading of each part signal from the memory (DS) to a memory output (SA1 to SA4) and a selector (SEL1 to SEL4). A coupling field may be composed of switch groups (SCH) arranged in columns and lines, as required. Each data outputs (DA1 to DA4) of one switch group (SCH MN) is connected to a connection input (VE1 to VE4) of the following switch group.
