In this paper we present that Post Dialling Delay in one telephone network depends on the service discipline in particular network nodes. It is indicated that deviation of PDD from its mean value decreases as the number of nodes included in one established connection increases. The consequence of this fact is that the condition of serving 95% of connections is more stringent in the connections with small number of network nodes included in the connection, while the condition dealing with the mean value of PDD is more stringent in the connections with great number of nodes.
