PURPOSE: An apparatus and a method for confirming the loading of a vocoder board algorithm in an IMT-2000 BSC(Base Station Controller) are provided to confirm whether the vocoder board algorithm is normally loaded and executed through a voice when the vocoder board algorithm is loaded in a DSP(Digital Signal Processor) of a vocoder board. CONSTITUTION: A plurality of flash memories(101) store a plurality of vocoder algorithms, respectively. A CPU(102) receives a vocoder algorithm conversion control signal from an access control processor, and selects an address line of a corresponding flash memory among a plurality of flash memories(101) and simultaneously outputs a reset control signal. A vocoder board(100) has a plurality of DSPs(103) for receiving the reset control signal from the CPU(102), reading and executing a corresponding algorithm among a plurality of vocoder algorithms stored in the flash memories(101), and extracting a loading testing voice data stored in the read algorithm to decode the extracted loading testing voice data. A codec(200) receives the loading testing voice data outputted from a corresponding DSP among a plurality of DSPs(103) and converts the received loading testing voice data into an analog signal(200). A transmitter/receiver(300) receives the analog loading testing voice data outputted from the codec(200) and outputs the received analog loading testing voice data to an operator(300).
