Design of VoIP Voice Terminal Based on AR1688
Abstract:Today, VOIP is considered more and more important in information network system. VOIP is not just a solution for voice communication, it can also be used in mixing voice, image and video. It is a kind of network communication technology which can support a variety of smart business. It is playing a pivotal role in the progress that IP Network replace the PSTN. VOIP terminal is an essential equipment in VOIP system. In this paper the author gives a design of VOIP voice terminal based on the SOC of AR1688. First is the introduction of the design of the electronic circuit, including the introduction of IC: AR1688, DM9003 and LM386, and the division of function blocks. After that the article deals with the design and function blocks of software. This VOIP terminal has the advantages in terms of good performance, stability, low-costs, etc., can be used either in company or at home. And now there is a great market demand of this kind of VOIP terminal.
