Abstract (en)

[origin: WO9848589A2] The invention relates to a method for operating a connection in an ISDN network (NE) with at least one DECT intermediate system (IS) in which for each connection the triplet terminal address (TEI 1)-call identification (CR2)-code of the communication service (BC 1) from the connections protocol are stored in a list (LIS). According to the invention, upon arrival of the acknowledgement (HOLD ACK) for holding a connection, this triple (TEI 1-CR 2-BC 1) is marked. Upon arrival of an acknowledgement (RETR ACK) for reactivation of a connection, a search is carried out for the marked call identification (CR 2) under the same terminal address (TEI 1) in the list, so that the DECT connection which is provided corresponds to the code of the communication service (BC 1) of the marked triple (TEI 1-CR 2-BC 1), and the marking (X) is ultimately deleted again.
