ROUTER FOR HDLC PACKET DATA TRANSMISSION

摘要

PURPOSE: A router for HDLC(high-level data link control) protocol packet data transfer is provided to transfer the HDLC packet data in one node by analyzing and processing high-speed HDLC packet data input in real time. CONSTITUTION: A GCIN(gateway communication interface network) interface board(100) connected to an MSC(mobile switching center) performs conversion of high-speed HDLC packet data from the MSC and pure data in real time to route the pure data. Several channel cards(200) perform conversion of the pure data from the GCIN interface board(100) and the HDLC packet data, and connect the HDLC packet data to several trunk links. Several line interface boards(300) perform network synchronization by connecting the channel cards(200) directly to several trunk links.
