PURPOSE: A communication service control system and a complex communication terminal apparatus for interfacing a digital subscriber line using the system are provided to offer a VoIP(Voice over Internet Protocol) function, a super speed Internet connection function, a home network connection function and an Ethernet connection function to a remote subscriber connected directly to a network side DSL(Digital Subscriber line) processing device in a DSLAM(Digital Subscriber Line Access Multiplexer). CONSTITUTION: A reset and clock unit(202) is connected to a local bus and then performs a function for supplying a power input reset signal and a switch reset input signal to a communication service controller(204) for the necessary time. Also, the reset and clock unit(202) provides clocks of 12MHz, 2.048MHz, and 25MHz required to the terminal apparatus. The clocks is inputted to the communication service controller(204), divided, become double and then provided to the respective devices. An input/output unit(201) is connected to the local bus and performs a function that is connected with an external input/output device. A memory unit(203) is connected to the local bus and stores a starting program or a terminal apparatus operating program. An USB(Universal Serial Bus) connection unit(205) is connected to the communication service controller(204) and also connected to a connection device having a USB port such as a computer, a camera and a monitor etc. with 12Mbps speed. A network connection unit(206) can be connected to a HomePNA(Home Phone line Network Alliance) or an Ethernet. A VoIP connection unit(207) performs functions for producing a tone necessary for a telephone function and converting digital/analog into analog/digital.
