Abstract
A method and apparatus for providing an interworking unit between ATM networks and IP networks. A gateway unit is provided that will interconnect a ATM (AAL2) based access/core network to an IP based (Mux in RTP). The gateway unit acts as an interface which is disposed between a first and second network, wherein the first network uses a first type of signaling and the second network uses a second type of signaling, and the interface translates signaling between the first and second networks. The interface further includes a control plane for translating signaling between the first and second network and/or a user plane for converting user data from the first type of signaling to the second type of signaling. The control plane maps services between the first and second networks and transfers the services between the first and second networks. The interface also includes at least one interface module and multiplexing module. The interface module includes a first type of interface module for providing connectivity to the first network and a second type of interface module for providing connectivity to the second network. The multiplexing modules includes a first type of multiplexing m…
