ABSTRACT:
A time division multiplex (TDM) switching network having TDM switching units which, through time position conversion, selectively assign time slots on connected TDM lines is described. The TDM lines are formed into a matrix, the crosspoints of which are connected by the TDM aforementioned switching units. The TDM switching units have a fixed traffic capacity which is defined by the maximum number of time slot connections that the switching units are capable of making between the TDM lines connected thereto. The fixed traffic capacity of the switching units is dependent on the size of the TDM switching network but smaller than the maximum rated traffic capacity of the TDM lines. As a result, in the event the TDM switching network is expanded, the fixed traffic capacity of the additional TDM switching units can be progressively reduced.
