Working Device for mapping a Circuit Network Data and Asynchronous Transfer Mode Network Data in a ATM Network and The Method Thereof

摘要

The present invention relates to an interworking device and an interworking method for mapping between network information and asynchronous transfer mode network information in an asynchronous transfer mode (ATM) network, and includes a vertical frame buffer for storing data flowing into or out of the network. A data format converter is configured between the Vertical Frame Buffer (VFB) and the Horizontal Cell Buffer (HCB) that stores data flowing into or out of the ATM network, and is interrupted by an interrupt generated during frame reception / transmission at the network connection. Insertion of CAS information by controlling the data format conversion unit by an operating control unit to convert between network data and ATM network data, and differentiate the operation of the control unit depending on the presence or absence of CAS (Channel Associate Signaling) information during data format conversion. And extraction operation can be easily performed, and then By in predicting the type of emulation circuit structure to a character asynchronous transfer to improve the data rate conversion mode network interworking method is presented for the mappings between the network information, and Asynchronous Transfer Mode network information.
