| Abstract: | An inferface circuit performing parallel communication between a computer and a program--controlled digital exchange for a practical fee--counter system is discribed in this paper. The inferface circuit consistsof large-scale integrated circuit components. The operation principles of the hardware is discussed in detail andthe design of the data receiving program is also discribed. |
