| Abstract: | A design and implementation of 32_way MFC/DTMF transceiver system in a small board, which fitted in the main control board is introduced in this paper. It can be used in middle or small scale CTI switches. Compare this with the implementation of ASIC, this system has smaller volume, higher processing density, and has higher performance cost ratio and flexible interface. |
