Abstract: There is disclosed, for use in an ATM network, a system for servicing an SVC connection between a first node and a second node operable to transmit and receive frame relay data frames, wherein the first node is coupled to an ATM access device incapable of providing to the first node support for switched virtual circuit (SVC) connections. The system comprises: 1) a connection controller capable of establishing a fixed connection between the ATM access device and a selected intermediate node in the ATM network; and 2) a frame relay proxy controller disposed at the selected intermediate node and adapted for communicating via the fixed connection established by the connection controller, wherein the frame relay proxy controller receives SVC signaling information from the first node via the fixed connection and establishes an SVC connection with the second node.

Abstract: Software inverse multiplexing within an Asynchronous Transfer Mode (ATM) communication network is provided by a first ATM switch receiving a stream of ATM cells over a high bandwidth communication link. A Segmentation and Re-assembly (SAR) module associated with the first ATM switch thereafter reassembles the received ATM cells into corresponding user packets. Control data identifying the sequence of assembled user packets are added to each user packet and de-assembled into corresponding ATM cells. The de-assembled ATM cells are then communicated over a plurality of low bandwidth communication links to a second ATM switch. The second ATM switch receives the transmitted ATM cells over said low bandwidth communications links. A SAR module associated with the second ATM switch thereafter reassembles the received ATM cells into corresponding user packets. Utilizing the enclosed control data, received user packets are re-synchronized into their original sequence.
