PURPOSE: A frame relay-to-ATM interface is provided to be capable of processing a large volume of data traffic with minimal deterioration in performance. CONSTITUTION: A frame relay-to-ATM interface circuit(200) is used in a processing network containing a first node to transmit and receive frame relay data and a second node to transmit and receive asynchronous transfer mode(ATM) data. A network interface for converting the frame relay data to ATM data comprising a frame relay interface circuit(201) to receive the frame relay data from the first node, an ATM interface circuit to transmit the ATM data to the second node, a data bus(203, 209) for coupling the frame relay interface circuit and the ATM interface circuit, the data bus to transfer frame payload data from the frame relay interface circuit to the ATM interface circuit, a data traffic controller(206) to receive frame header data from the frame relay interface circuit and control transfers of the frame payload data from the frame relay interface circuit to the ATM interface circuit, and a bridge(205) for coupling the data traffic controller to the data bus, the bridge isolating the data traffic controller from the transfers of the frame payload data.
