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.
