| Abstract: | A design of LAN/Intranet oriented IP voice terminal is proposed. This terminal can be used either as a network terminal or as a device of other terminals. Fixed point DSP processor with low power waste and general-purpose micro-controller are adopted as voice CODEC and to provide internet access service respectively, offering multiple communication interfaces at high or low speed. |
