Abstract: A reference network node in a circuit-switched network obtains information about a partner network node by including a requesting element in a connection SETUP message sent to the partner network node. The partner network node responds with identification parameters included in response messages (for example, a CONNECT message). The reference network node uses the received identification parameters to send appropriate configuration information (for example, connection control of transmission links) to the partner network node.

Abstract: A method is provided for initiating a configuration after the interruption of at least two ring-shaped networks arranged in parallel. After the appearance of malfunctions in the ring lines and ring switching matrix devices in at least two-of-n ring-shaped networks, a configuring in the sense of forming those ring network portions that are still intact into a new ring-shaped network is initiated. Based on the knowledge of the position of the subscriber equipment (interpretation of the address table information) and on the transmission of interrupt information given ring interruptions, the configuring or, respectively, "loop back" connecting is initiated after the identification of the reception and transmission of interrupt information or the identification of the transmission of interrupt information dependent on the position of the appertaining subscriber equipment.

Abstract: A packet sequence is formed in a subscriber station which monitors a token ring network including a number of subscriber stations, the packet sequence containing an address recognition bit at a binary "0" state, a broadcast sequence identifying the packet information as a broadcast packet sequence, and the information field thereof containing either an address signaling request or an address signaling request in the address of its own subscriber station. In the respective following subscriber stations, the received binary state of the address recognition bit is modified to a binary "1" and a further broadcast packet information sequence is formed such that the address recognition bit contains a binary "0" and the most-recently received address is entered into the information field with either the address of the preceding subscriber station or with its own address.
