A telecommunication network includes a number of mutually coupled private branch exchanges to which are assigned respective storage locations for storing switching data and which include processors for determining the most favorable route in dependence on the stored switching data to a subscriber terminal arranged inside or outside the telecommunication network. In the network, an outgoing route from one of the private branch exchanges is led through one or more of the other private branch exchanges and/or through one or more other telecommunication networks.
