ABSTRACT:
In a process for measuring switching delays in telecommunication networks having an asynchronous transfer mode, where cells containing information experience switching delays at switching exchanges, selected cells are provided with a counter, are switched in the same manner as other cells in switching exchanges, and are transmitted via the telecommunication network. The counter contained within the cell in the switching exchanges is increased in each case by a value corresponding to the switching delay, and the counter is read out after the transmission.
