Abstract:
1. A communication terminal for a wire and wireless network phone comprising: a communication service controller, including a RISC (reduced instruction set computer) processor, for processing protocols that satisfy respective communication interfaces in hardware and software manners; a reset unit for applying a reset signal to be used for the communication service controller; a clock signal unit for supplying clock signals needed for the communication service controller; a memory connected to the communication service controller, for storing a start program, a terminal management program, user data, and various application programs; and access units for providing a VoIP (voice over Internet protocol) telephone function, a DSL (digital subscriber line) access function, an analog telephone function, an Ethernet access function, a wireless network access function, and an EIA232 (electronic industries association 232) access function, wherein the communication service controller further comprises: an AHB (advanced host bus) for connecting the RISC processor to the reset unit, the clock signal unit, and the memory through respective controllers; and an APB (advanced peripheral bus) coupled to the AHB for connecting the access units through respective interfaces, wherein the access units comprise: a DSL access unit, connected between the communication service controller and a DSL, for performing an access function of the DSL of the terminal; and an Ethernet physical access unit, connected between the communication service controller and an Ethernet, for performing an access function of an Ethernet physical layer, wherein the communication terminal for a wire and wireless network phone is connected to a network through an Ethernet line and to the DSL access unit through a DSL, and the DSL access unit is connected to the network and a PSTN (public switched telephone network) through an ATM (Asynchronous Transfer Mode) switch.
