Abstract: A method for setting up virtual connections in packet switching networks is disclosed wherein a virtual connection within a second packet switching network is used to maintain or create a virtual connection between subscriber equipment with a first packet switching network. Signaling equipment located within first packet switching network, but which is not directly connected to the subscriber equipment, employs the signaling protocol of the second packet switching network when initiating the second virtual connection so that it is not necessary for the second packet switching network to recognize a specific signaling protocol.

Abstract: A method and circuit arrangement for the acceptance and temporary storage of data signals in a data switching system includes a data communication control to which the data signals are supplied, a connection memory which makes information available to the data communication control, and a memory arrangement for serving as the data storage. The connection memory stores the address of a memory area within the memory arrangement which is available for the acceptance and temporary storage of data signals in the connection memory for each line section. In response to the first activation of such a memory area, the addresses of additional memory areas are made available to the data communication control.
