As shown in FIG. 3, the IAD according to the present invention is largely composed of nine matching units for external matching, and a broadband access modem and a memory matching unit.

Nine matching ports for matching with external devices are Universal Serial Bus (31) (hereinafter referred to as "USB"), x-type digital subscriber line matching unit (32), 10/100 base T Ethernet (32 ), ATM25 (33), Universal Test & Operations Phisical Layer interface for ATM Level I, II, hereinafter referred to as "UTOPIA Level I, II" (35) , Universal asynchronous receiver / transmitter (hereinafter referred to as "UART") 40, in-circuit emulation (hereinafter referred to as "ICE") 41, general purpose input / output (General Purpose Input / Output, hereinafter referred to as "GPIO") 42, and External Input / Output (hereinafter referred to as "EIP") 43.

As shown in FIG. 2, the IAD may be directly connected to an access gateway 24, which is a core network, to collectively provide voice service and high speed data service without separation. In addition, the IAD 21 may be connected to the DSLAM 22 to provide a voice service and a high speed data service through an access gateway 24 which is a core network.
