The check of the admissibility of the set-up of a virtual connection via such a transmission line occurs in two steps. In a first step, a first capacity limit value, or a second capacity limit value that is lower in comparison thereto, is defined for the ATM transmission line based on the measure of the message cell streams having high cell loss priority, including the message cell stream to be potentially taken into consideration to be set-up. Proceeding on the basis of the respectively defined capacity limit value, a check is then made in a second step to see whether--taking into account all message cell streams transmitted via the corresponding ATM transmission line--a set-up of a virtual connection that has just been requested is possible.Other References
