<p>PURPOSE: A connection device of a packet exchange and a packet terminal is provided to connect a signal converter to a packet exchange through an RS-232C line method, and to connect a signal converter of a packet terminal with the packet terminal, thereby extending a transmission distance. CONSTITUTION: A data connector(301) is connected in an RS-232C method of a packet communication unit. An RS-232C driver(303) is driven to transmit data through the RS-232C method in connection with the data connector(301). A signal processor(305) interleaves/deinterleaves a signal transceived through the RS-232C driver(303), and corrects an error. A line interface(306) transmits a digital signal passing through the signal processor(305) into an analog signal with other side signal converter. A line terminal(307) connects the line interface(306) with two wires.</p> |
