摘　　要：该文提出一种基于软交换技术的报警接入网关的设计方案。以TMS320VC5402和EMP240T100c5N为核心设计了硬件电路，制定了报警接入网关的呼叫控制协议wMGcP，采用分层结构的思想在DSP平台上进行了实现。通过该报警接入网关，能够将企业内部的安全报警系统与基于企业内部局域网的VoIP通信系统对接起来，实现了报警音通过网络电话终端进行播放。Based on the advantages of Soft-switch, a kind of alarm access gateway was designed. TMS320VC5402 and EPM240TI00C5N as the core were adopted to design the hardware circuit. WMGCP was developed as call control protocol between alarm access gateway and MGC and implemented on DSP platform and using the ideological of stratified structure. The security alarm system in Enterprise Internal can connect with the LAN-based VoIP Communication System through alarm access gateway. It can also achieve the alarm sound to play through the network phone terminal.
