AN ELECTRONIC EXCHANGE SYSTEM ABSTRACT OF THE DISCLOSURE A small scale electronic telephone exchange system having a plurality of trunks and a central computer has been disclosed. The trunks function to process the real time operation and, therefore, the central computer does not need to operate on a real time basis. The central computer always scanns the condition of the trunks and the subscriber's telephone terminals and, upon detecting the change of said condition, it analyzes said change and performs the necessary process for said change. The present exchange system provides many new services but the cost of the system is reasonable. - 1 -
