Switching network for switching channels

A switching network for switching nodes (VK) of a communication system for switching channels which are associated with one or more time slots of a frame of a time-division multiplex signal consisting of component signals,

• wherein at least one switch group (SCH) has a plurality of data inputs (DE1 to DE4) and a plurality of data outputs (DA1 to DA4),
• wherein channels of an incoming time-division multiplex signal received at one of the plurality of data inputs (DE1 to DE4) can be switched to an outgoing time-division multiplex signal at one of the plurality of data outputs (DA1 to DA4),
• wherein said at least one switch group (SCH) includes at least one data memory (DS) which temporarily stores component signals transmitted in individual time slots and has a plurality of memory inputs (SE1 to SE4) and memory outputs (SA1 to SA4) via which data is written and read, respectively, the plurality of memory inputs (SE1 to SE4) being connected to the plurality of data inputs (DE1 to DE4), and the plurality of memory outputs (SA1 to SA4) being respectively connected to the plurality of data outputs (DA1 to DA4), and
• wherein the component signals are addressed on a periodically recurring basis in said at least one data memory (DS),
• characterized in that
• said at least one data memory (DS) has at least two independently readable memory outputs (SA1, SA2;
• SA3, SA4), and
• each memory output (SA1 to SA4) has associated therewith a connect memory (VB1 to VB4) via which an address for reading said at least one data memory (DS) is specified in order to switch selectively the channels in a selected sequence to a respective one of said plurality of selected data outputs (DA1 to DA4).
