ABSTRACT:
A time division multiplex (TDM) switching network for a telecommunications system or the like is described. The network contains switching network units for causing time slots formed on connected TDM lines to be assigned on a space/time division basis. The TDM lines are formed into trunk groups, and the trunk groups, respectively, form the row and column lines of a matrix. The switching network units are arranged at the crosspoints of the trunk groups to form the crosspoint switching elements between the intersecting trunk groups or between lines of the same trunk group. Each switching network unit is constructed to have a capacity for completing a number of connections less than the number of connections the crosspoint with which it is associated is capable of carrying.
