Abstract
The time division multiplex switching network has switching network units (KE) which in each case effect a spatial and a temporal allocation of time channels formed on connected time division multiplex lines. For a switching network of this type, a structure is indicated in which, using a single type of switching network unit and starting with the lowest configuration levels, expansions of any size can be undertaken in simple fashion by adding further switching network units without any preparatory work having to be carried out for this purpose during a basic configuration. To achieve this, the time division multiplex lines in the form of groups of lines (1Z to nZ; 1S to mS) form a matrix-type arrangement at whose intersection points at least one switching network unit (KE) is in each case connected to the individual lines of two line groups (Z, S) via which connections between time division multiplex lines of the two line groups (S, Z) as well as connections between time division multiplex lines within the two groups can be set up, and the switching network units (KE) have a lower traffic handling capacity than that which corresponds to full accessibility. <IMAGE>
