SPC Exchange Experiment System Based on FPGA

Abstract:

In this paper, we propose a new type of SPC (Stored Program Control) exchange experiment system, which adapt to the reform of the program-controlled exchange technology experiment teaching. The system uses FPGA chip to complete the core of telephone exchange such as timeslot generation, signal tone generation, user calls, voice data exchange functions, it can also achieve secondary development and teaching function expansion through the online programming downloads. The PC software in the system completes the user calls data statistics and analysis function. The experiment system in use reflects its development and convenient, the function is perfect characteristics, and has good application prospect.
