Patent ID: 6941364

Claim:
A modular-type home gateway system comprising: a HomePNA(Home Phoneline Network Alliance) controller connected to a prior home telephone line, for providing a home network interface; an ADSL(Asymmetric Digital Subscriber Line) controller connected to an existing outdoor telephone line, for providing an access network interface; and a system controller for controlling the HomePNA controller and the ADSL controller, wherein the HomePNA controller and the ADSL controller are formed as a modular type that are detachably connected to the system controller through a PCMCIA (Personal Computer Memory Card International Association) interface unit, and that provides a bridge function between a home network and an access network, wherein the PCMCIA interface unit includes: a PCMCIA slot A interface unit for an interface function between the ADSL controller and the system controller; and a PCMCIA slot B interface unit for an interface function between the HomePNA controller and the system controller: wherein each of the PCMCIA slot A interface unit and the PCMCIA slot B interface unit includes: an address latch part for controlling an address signal between the system controller and a PCMCIA slot; a data buffer for converting PCMCIA slot data to CPU data according to a state of a PCMCIA slot card enabling signal received from the system controller, and for transmitting the PCMCIA slot data to the system controller; a control signal buffer for converting a CPU control signal to a PCMCIA slot control signal according to a state of the PCMCIA slot card enabling signal received from the system controller; and a state signal buffer for converting a PCMCIA slot state signal to a CPU state signal according to a state of the PCMCIA slot card enabling signal generated from the system controller, and transmitting it to the system controller, wherein the ADSL controller includes: an ADSL modulation/demodulation controller for processing a data switching between the PCMCIA slot A interface unit and an ADSL AFE(Analog Front End) controller, and for transmitting a resultant signal to the PCMCIA slot A interface unit; and the ADSL AFE controller for interchanging an ADSL transmitting/receiving signal with the access network through an outdoor telephone line after completing the data switching with the ADSL modulation/demodulation controller, and for transmitting the resultant signal to the ADSL modulation/demodulation controller.
