Abstract
The ATM communication equipment (KE) serves the purpose of forwarding message cells supplied via at least one offering trunk (E1, . . . , En) during to course of virtual connections with a serving trunk arrangement (A1, . . . , An) coming into consideration for the respective virtual connection. Characteristic parameters as well as at least two different priorities are thereby defined for the respective virtual connection during the course of the call set up. The respective serving trunk arrangement has a handling device (BHE) allocated to it that has a central cell memory (CM) in which call-associated cell waiting lists are established for storing message cells. A control device (STE) in which an allocation table (LUT) is kept is connected to the cell memory. This allocation table allocates a waiting list identifier as well as a priority identifier to the call information (VPA/VCI) carried in the message cells. Based on the criterion of the individual priority identifiers, the appertaining waiting list identifiers are inserted into a reference waiting list (Q1,Q2) allocated to the respective priority. These reference waiting lists are processed with different priorities, whereby t…
