PURPOSE: A matching module for a digital user in a remote access server is provided to maximize acceptance of modem ports when designing a module for a modem user of the remote access server and to reduce a load of an interface between modules and an additional control logic. CONSTITUTION: A matching module for a digital user in a remote access server includes a packet controller(10), a transmitting/receiving FIFO(First In First Out)(20), a FIFO processor(30), SDRAM(40,100), a decoder(50), a flash memory(60), a ROM(70), an EEPROM(80), an ethernet transferring portion(90), a CPU(Central Processing Unit((100), an interrupt processor(120) and a modem(150). The packet controller transfers data via a packet bus after controlling a packet. The transmitting/receiving FIFO transmits and receives the data of the packet controller and transfers sequentially. The FIFO processor processes the data of the transmitting/receiving FIFO. The SDRAM(40,100), the decoder(50), the flash memory(60), the ROM(70) and the EEPROM(80) transmits and receives data with a system via a data bus. The ethernet transferring portion transfers data via an ethernet bus. The CPU transfers processed data to the ethernet transferring portion and controls the system. The interrupt processor receives an interrupt vector value from the CPU and processes the interrupt signal. The modem communicates a trunk interface module via a TDM(Time Division Multiplexing) bus by transmitting/receiving data of the CPU and the interrupt signal of the interrupt processor and also transmits and receives data with the ROM(130) and SRAM(140).
