Abstract
The system and method of the present invention provide a seamless approach for providing ATM connectivity for a Frame Relay DTE using an intelligent Terminal Adapter (TA). Using the system and method of the present invention, an enhanced Frame Relay protocol runs between the DTE and the ATM TA, the Frame Relay DTE is provided with not only the connectivity to the ATM network but also the full advantages of ATM transport mechanism. For instance, the FR DTE can choose to transmit its data using ATM Adaptation Layer (AAL) 1,3/4 or 5. Using the system and method of the present invention, a FR DTE may communicate with another FR DTE or to an ATM DTE through wide area or local area ATM network. The Frame Relay DTE can send data, image, voice, or video traffics across the ATM network via the FR/ATM terminal adapter.
