PURPOSE: A method and device for detecting and transmitting an error using a PLD(Programmable Logic Device) is provided to simplify configuration of an IPC module and to reduce a cost for designing a system. CONSTITUTION: A line interface module(300) communicates with a management module(320). The line interface module(300) transmits data to an IPC module(310). The IPC module(310) processes data transmitted from the line interface module(300) through the management module(320). The IPC module(310) includes a switch module(314) and a PLD(318). The switch module(314) selects a path of the data transmitted from the line interface module(300) and transmits the data through the path to the management module(320). The PLD(318) senses a signal transmission process between the line interface module(300) and the management module(320) and recognizes an error. The PLD(318) transmits a recognized error signal to the management module(320). The management module(320) receives the error signal transmitted from the PLD(318) and controls the error.
