PURPOSE: A device for controlling a base station remote restart board is provided to enable a user to remotely restart a remote restart board via a PSTN through a control board without operating time intervals, thereby enabling the user to simply control a base station transmission path interface board. CONSTITUTION: A modem(3) converts a remote authentication signal for restarting an LICA(Line Interface Control Assembly) board(1) into a transmission signal of a PSTN(2), and outputs the converted signal. An FPGA(Field Programmable Gate Array)(4) stores the remote authentication signal. An MCU(Micro Control Unit)(5) automatically transmits an authentication code signal stored in the FPGA(4) at set time intervals by using an internal timer. A keypad(6) inputs a functional setup signal of a user to the MCU(5). A ROM(7) stores a processing program in accordance with a restart remote control function of the LICA board(1). An RAM(8) temporarily stores processing information of the MCU(5). |
