    产品概述

    BM430 采用成熟的 VoIP 架构,支持标准 SIP 通信。媒体传输基于 IP、RTP 和 RTSP 协议,可与 SIP 服务器、IP PBX 系统、调度平台、对讲系统和广播呼叫方案连接。板卡支持两路 SIP 线路,适用于紧急呼叫、普通通信、广播联动和调度集成。

    主板支持数字全双工免提通信,可在工业环境中提供清晰且响亮的语音效果。它可使用板载 3W 扬声器输出,也可通过音频线路输出接口连接外部功放板,方便客户根据不同声音覆盖需求设计产品。

    BM430 核心特点

    集成式 SIP 通信平台

    BM430 支持 SIP 2.0 通信,可注册到 SIP 服务器、IP PBX 系统或调度平台。它支持两个 SIP 账号,使一台设备能够处理紧急呼叫、对讲呼叫、调度呼叫和广播呼叫等多种通信场景。

    板卡支持常见语音编解码,包括 G.711a/u、G.723.1、G.726、G.729A/B、iLBC、G.722 和 Opus,有助于确保与不同 SIP 平台和音频环境的灵活兼容。

    音频、视频与对讲功能

    BM430 支持免提扬声器、免提麦克风、手柄接口、音频线路输出和摄像头接口。可根据项目需求,用于开发纯音频或音视频工业通信终端。

    凭借 H.264 视频解码和 QVGA 视频支持,BM430 可应用于 SIP 视频对讲产品、带摄像头模块的紧急呼叫站、门禁通信终端和可视化调度应用。

    灵活的接口设计

    BM430 提供丰富的硬件接口,便于定制化工业电话机设计。接口包括显示屏接口、键盘矩阵接口、手柄接口、免提扬声器接口、免提麦克风接口、音频线路输出、叉簧检测、摄像头接口、RS485 接口、继电器输入/输出、双 RJ45 以太网口、DC 电源输入以及选配 WiFi 天线接口。

    6×6 矩阵键盘接口最多支持 36 个按键,包括数字键、导航键、功能键、音量键、静音键、视频通话键、免提键和可编程 DSS 快速拨号键。这使板卡既适用于单一紧急按键产品,也适用于全键盘工业电话终端。
