  • 贝克 SBC3000是一款高性能、电信级会话边界控制器,专为中小型电信运营商量身打造,可全面支持SIP网络安全、接入管理、互联互通、路由/策略控制、信令流管理、服务质量(QoS)及媒体处理。设备搭载多核处理器、非阻塞千兆交换架构与嵌入式Linux操作系统,以低功耗实现卓越性能,同时具备热插拔冗余电源、双系统热备份(HA)及WebRTC支持,确保电信级可靠性。

    SBC3000会话边界控制器

    无缝网络互联与兼容性

    其核心优势在于实现灵活可靠的网络互联。SBC3000完全兼容标准SIP协议,可与IP多媒体子系统(IMS)架构无缝整合,支持与现有网络基础设施顺畅互操作。具备NAT/PAT穿透能力,适配各类网络拓扑,确保不同网络中终端设备的无缝通信。
    配备E1接口,可直接连接传统PBX系统及PSTN线路,在保留既有基础设施投资的同时,助力向IP-based通信平滑过渡。支持最多128条SIP中继,提供负载均衡功能,优化网络流量分配,提升服务可用性。SBC3000还支持Windows/Mac/iOS/Android四大平台的SDK集成,可实现定制化应用开发及网络语音编码优化,满足特定业务需求。此外,针对Trunk SBC与WebRTC SBC场景均提供双系统热备份(1+1),最大限度减少停机时间,保障持续运行。

    卓越性能与媒体处理

    SBC3000具备出色性能,可应对高负载电信运营场景。单台设备支持最多2000个并发会话及1500个并发媒体转码会话,非转码并发呼叫(最多3000路)与WebRTC注册用户(最多10000名)容量可灵活扩展。每秒可处理150次呼叫(CPS)及200次注册(CPS),高效应对大容量流量峰值。

    媒体处理方面,设备支持G.711a/u、G.723、G.729、G.726、AMR、OPUS、iLBC等多款行业标准编解码器,实现语音质量与带宽效率的最优平衡。支持WebRTC-based语音及视频通话,满足现代统一通信需求。WebRTC SBC配置提供200路并发非转码呼叫(可扩展至3000路)及200个转码许可(G.711/G.729/OPUS编解码器,可扩展至800个),为用户规模增长提供灵活适配能力。

    高性价比

    强劲安全与可靠性

    安全性是SBC3000的核心设计原则,配备全方位防护机制保障SIP网络安全。集成VoIP防火墙,可防御DoS/DDoS攻击、UDP洪水攻击、TCP洪水攻击,并提供基于策略的IP及SIP防攻击措施。设备可检测并处理异常数据包,防范潜在网络中断及未授权访问。

    数据传输安全方面,支持SIP over TLS、SRTP及DTLS-SRTP加密,保护信令与语音媒体免受拦截与篡改。额外安全功能包括拓扑隐藏、智能带宽限制、动态黑名单、主被叫号码黑白名单及访问控制列表(ACL)管理,实现网络访问与流量的精细化控制。设备通过热插拔冗余电源(100-240VAC,50-60Hz)进一步提升可靠性,确保不间断运行。紧凑的1U设计(437×320×44mm,6kg)及宽泛的运行参数(工作温度0℃~45℃、存储温度-20℃~80℃、无冷凝湿度10%-90%),使其可适配各类部署环境。

    易管理与维护

    设备采用用户友好设计,通过直观工具简化配置与维护流程。虽未明确说明具体远程配置细节,但提供核心管理功能以优化运营效率。管理员可借助系统日志、操作日志等全面的日志功能,实时监控网络活动并高效排查问题。设备的坚固设计与标准化协议降低了维护复杂度,适用于技术资源有限的运营场景。

    结论

    贝克 SBC3000将高性能、电信级可靠性、强劲安全性与灵活互联性整合于紧凑可扩展的设备中。专为中小型电信运营商打造,满足SIP网络互联、安全防护与媒体处理的核心需求,同时支持既有基础设施与现代WebRTC-based通信。凭借出色的扩展性、全面的功能配置及低运营成本,SBC3000成为构建具备韧性、面向未来的IP通信网络的可靠解决方案,可灵活适配不断增长的业务需求。

常见问题

什么是ATEX?


ATEX是大气可爆物的缩写,是一套欧盟(欧盟)指令和标准,用于规范潜在爆炸性环境中使用的设备和保护系统。
这些标准旨在确保机械、电气设备和相关部件在可能存在易燃气体、蒸气、雾气或可燃粉尘的环境中不会成为点火源。ATEX适用于欧盟境内的设备制造商和向欧盟市场出口产品的制造商。

什么是IECEx?


IECEx是IEC爆炸性环境中使用设备认证体系的缩写,是由国际电工委员会(IEC)开发和管理的国际认证体系,旨在促进潜在爆炸性环境中使用的设备和部件的全球贸易。
IECEx系统的核心目标是建立一套全球公认的统一标准和认证程序。这消除了制造商为不同市场获得多个单独认证的需要,从而减少了贸易的技术壁垒,并确保跨地区的产品安全一致性。
