E-Fiji A test device of the former electronic exchanger

摘要

The present invention relates to an electronic exchanger, and more particularly, to a Field Programmable Gate Array (FPGA) test device (hereinafter, referred to as " FPGA ") /RTI ;The present invention can easily test the normal operation of the LCDC without requiring expensive test equipment such as an oscilloscope and an expander without prying the Link Control & Clock Distribution Card (LCDC) from the system, It is possible to judge whether the LCDC is operating normally or to perform a corrective action.
