The measurement covers a typical range of components. The selection follows the most current and most frequently used products as of "April 2009".
The measured values apply if the network has been configured correctly. Due to system-internal error control, an incorrect or incomplete configuration causes significantly deviating times.
All measured values were acquired under specific boundary conditions (configurations, parameterizations).
All settings essential for the measurement are listed in the table below. Default values are used for all settings which are not listed.
