The Design And Realization Of Program-controlled Exchange System Of Teaching Experiments

Stored-program control exchange is an important part in current communication system, because of its advancing technology and universal application. Now, stored-program control exchange technology is one of core courses for the students who major in communication in a university. The experiment device for teaching stored-program control exchange technology, is used in practice teaching of the course. The device can help students master and comprehend the content of this course. Hardware and software of the experiment device are designed in this thesis. The device can be used to for the experiments of user interface, network switch, relay interface, and system control. These functions can match the requirement of the course.In this paper, following contents are covered: design the architecture, and function module; select components; design circuit for user interface, switch network, CPU control, and signaling system; design PCB board and debug it; design software module and detail function; test and validate the system. The experiment device designed in this thesis has token effect by applying it in practice teaching.
