Abstract

A communications network having a master subscriber M and at least one slave subscriber. At least one distribution node CU1, CU2, CU3, CU4 is provided which has a plurality of input/output interfaces, each of which is connected to a network segment, the master subscriber M arranged in a first network segment M1 and the slave subscriber arranged in a second network segment S1, S2, S3, S4, S5. Data is exchanged between the master subscriber M and the slave subscriber in the form of telegrams initiated by the master subscriber. The telegrams to be sent from the slave subscriber to the master subscriber are each assigned control data containing a forwarding time information when the corresponding telegram is to be output from the distribution node via the input/output interface in the direction of the first network segment comprising the master subscriber, the forwarding time information determined by the master subscriber M.
