Abstract

To determine the quality of virtual circuits extending via input lines (E1, ..., En) and output lines (A1, ..., An) of an ATM switching arrangement (VA), it is provided that the number of information cells received and output is connection-individually separately verified in the ATM switching arrangement by means of the cell headers of the information cells received via the input lines and, respectively, output to the output lines. Following the release of the respective virtual connection, the loss rate of the information cells is then determined as a measure of the quality of the respective virtual connection from the number of information cells received and output which has previously been separately verified. <IMAGE>
