Abstract: In a method and arrangement for controlling accesses of network terminal units to predetermined resources of a packet-oriented communication network, in the context of connection setups, partial communication network resources requested by network terminal units arranged in a packet-oriented communication network are assigned to these units by entering access authorizations into annularly chained memories. By sampling the memories, the access to the assigned partial communication network resources is granted to the network terminal units in a manner corresponding to the entered access authorizations. Advantageously, the communication network resources are distributed to arbitrarily many network terminal units.
