Abstract

An existing logical data link between a first subscriber terminal connected to a subscriber line of a telecommunications network and a switching center of the telecommunications network is transferred from a first subscriber terminal to a second subscriber terminal which is connected to the subscriber line of the first subscriber terminal or to another subscriber line of the second telecommunications network. The second subscriber terminal receives a message sent from the first subscriber terminal concerning the communication state of the existing logical data link and takes over this data link in the reported communication state, adapting its own state.
