The circuit arrangement is used in the transmission of information cells via virtual links for controlling the flow rates fixed in each case for the individual virtual links in an ATM switching system (BVA). In the ATM switching system, a number of counting devices (BSP, Reg2, Reg3, ADD) corresponding to the number of virtual links passing via the respective feeder line is assigned to each of the feeder lines (E1,... En) provided to receive information cells. These counting devices can be activated individually when information cells occur, according to the cell header contained in each case therein which designates the respective virtual link. In each case they record, by means of an individually fixed counting response, the flow rate used via the respective virtual link during the transmission of information cells. If a specified flow rate is exceeded, this is indicated by an alarm signal from the respective counting device. …<IMAGE>… |
