Communication processing system / complex network matching device and data transmission method using the same

摘要

The present invention relates to a communication processing system / complex network matching apparatus and a data transmission method using the same, comprising: a communication processing system matching means, a LAN matching means and an ATM matching means each having two transmission / reception FIFOs, and the respective matching means. A cam for creating and storing a destination-specific table of the received data, three first data memories for storing the data for transmission of each matching means, and three second data memories for storing the data for reception of each matching means. And checking whether there is data flowing from a communication processing system, a LAN, or an ATM network, storing the incoming data in the second data memory and outputting the storage state, using the cam. Analyzing the destination of the received data at high speed; and receiving the received data according to the analyzed destination. Converting into a system data format or an Ethernet LAN data format or an ATM data format, storing it in the first data memory and outputting a storage state; and reading the data and transmitting the data at high speed through a FIFO of a destination matching means, and then transmitting the data. It is composed of the steps of outputting the general purpose telephone network (PSTN), data network (PSDN) subscribers have the advantage that can send and receive information connected to the ATM network, LAN through the communication processing system.
