PURPOSE: An integrated access gateway system is provided to supply a system structure using a statistical multiplex, and to integratedly supply narrowband and broadband data services in one network structure, thereby enabling integrated equipment management for individual equipment management. CONSTITUTION: A narrowband processor(110) comprises as follows. A narrowband subscriber interface(112) processes general phone subscribers and ISDN subscribers. A DTMF device(113) interprets receiving numbers of the subscribers. A TDM pool unit(114) performs TDM switching and interface functions. A test device(115) performs test functions of subscriber line and subscriber circuits. A tone device(116) supplies a tone to a subscriber device. The first controller(117) controls a received signal of a main controller(140). A voice packet processor(120) comprises as follows. An ATM interface(122) interfaces a voice in AAL2, and interfaces control data in AAL5. An AAL2 processor(123) performs AAL2 packet conversion for received data. An AAL5 processor(124) performs AAL5 packet conversion for the data. A vocoder(125) compresses the data to restore the data, and transmits the data to a TDM interface(121). A broadband processor(130) comprises as follows. An ATM interface(131) supplies an AAL5 signal only. An xDSL subscriber interface(132) receives xDSL subscribers. An exclusive subscriber interface(133) supplies an exclusive line service.
