| Abstract: | A DSP-based solution to LAN/Intranet-oriented IP telephone is presented. This IP Telephone can be used either as a desktop PC peripheral or as an Intranet network terminal. Its cores are TMS320C5402 in charge of voice code and MPC860T in charge of communications protocol processing and control logic. Several kinds of interface including USB, RS232 and RJ45 are designed to allow IP telephone to connect with other equipment in flexible ways. Some details of hardware architecture are discussed in this paper. |
