  • 貝克SBC3000是一款高效能、電信級會話邊界控制器,專為中小規模電信業者量身打造,可全面支援SIP網路安全、存取管理、互連互通、路由/政策控制、訊號流管理、服務品質(QoS)及媒體處理。設備搭載多核處理器、非阻塞式千兆交換架構與嵌入式Linux作業系統,以低功耗實現卓越效能,同時具備熱插拔備援電源、雙系統熱備份(HA)及WebRTC支援,確保電信級可靠度。

    SBC3000會話邊界控制器

    無縫網路互連與相容性

    其核心優勢在於實現靈活可靠的網路互連。SBC3000完全相容標準SIP協定,可與IP多媒體子系統(IMS)架構無縫整合,支援與既有網路基礎建設順暢互動。具備NAT/PAT穿透能力,可適配各類網路拓撲,確保不同網路中終端設備的無縫通訊。
    配備E1介面,可直接連接傳統PBX系統及PSTN線路,在保留既有基礎建設投資的同時,協助向IP基礎通訊平順過渡。支援多達128條SIP中繼線,提供負載均衡功能,優化網路流量分配,提升服務可用性。SBC3000另支援Windows/Mac/iOS/Android四大平台的SDK整合,可實現客製化應用程式開發及網路語音編碼最佳化,满足特定業務需求。此外,針對Trunk SBC與WebRTC SBC場景均提供雙系統熱備份(1+1),最大限度減少停機時間,保障持續運作。

    卓越效能與媒體處理

    SBC3000具備出色效能,可應對高負載電信營運場景。單台設備支援多達2000個同時線路及1500個同時媒體轉碼工作階段,非轉碼同時通話(最多3000路)與WebRTC註冊使用者(最多10000名)容量可靈活擴充。每秒可處理150次通話(CPS)及200次註冊(CPS),高效應對大容量流量峰值。

    媒體處理方面,設備支援G.711a/u、G.723、G.729、G.726、AMR、OPUS、iLBC等多款業界標準編解碼器,實現語音品質與頻寬效率的最佳平衡。支援基於WebRTC的語音及視訊通話,满足現代統一通訊需求。WebRTC SBC配置提供200路同時非轉碼通話(可擴充至3000路)及200個轉碼授權(G.711/G.729/OPUS編解碼器,可擴充至800個),為使用者規模增長提供靈活適配能力。

    高CP值

    堅固安全與可靠度

    安全性是SBC3000的核心設計原則,配備全方位防護機制保障SIP網路安全。整合VoIP防火牆,可防禦DoS/DDoS攻擊、UDP洪水攻擊、TCP洪水攻擊,並提供基於政策的IP及SIP防攻擊措施。設備可偵測並處理異常封包,防範潛在網路中斷及未授權存取。

    資料傳輸安全方面,支援SIP over TLS、SRTP及DTLS-SRTP加密技術,保護訊號與語音媒體免於攔截與竄改。額外安全功能包括拓撲隱藏、智慧頻寬限制、動態黑名單、來電/去電號碼黑名單/白名單及存取控制清單(ACL)管理,實現網路存取與流量的精細化控制。設備透過熱插拔備援電源(100-240VAC,50-60Hz)進一步提升可靠度,確保不間斷運作。緊湊的1U設計(437×320×44mm,6kg)及寬廣的運作參數(工作溫度0℃~45℃、儲存溫度-20℃~80℃、無凝結濕度10%-90%),使其可適配各類部署環境。

    易於管理與維護

    設備採用使用者友善設計,透過直覺式工具簡化設定與維護流程。雖未明確說明具體遠端佈署細節,但提供核心管理功能以優化營運效率。管理員可運用系統日誌、操作日誌等全面的日誌功能,即時監控網路活動並高效排除問題。設備的堅固設計與標準化協定降低了維護複雜度,適用於技術資源有限的營運場景。

    結論

    貝克SBC3000將高效能、電信級可靠度、堅固安全性與靈活互連性整合於緊湊可擴充的設備中。專為中小規模電信業者打造,满足SIP網路互連、安全防護與媒體處理的核心需求,同時支援既有基礎建設與現代WebRTC基礎通訊。憑藉出色的擴充性、全面的功能配置及低營運成本,SBC3000成為建構具備韌性、面向未來的IP通訊網路的可靠解決方案,可靈活適配不斷增長的業務需求。

常見問題

什麼是ATEX?


ATEX是大氣可爆物的縮寫,是一套歐盟(歐盟)指令和標準,用於規範潛在爆炸性環境中使用的設備和保護系統。
這些標準旨在確保機械、電氣設備和相關部件在可能存在易燃氣體、蒸氣、霧氣或可燃粉塵的環境中不會成爲點火源。ATEX適用於歐盟境內的設備製造商和向歐盟市場出口產品的製造商。

什麼是IECEx?


IECEx是IEC爆炸性環境中使用設備認證體系的縮寫,是由國際電工委員會(IEC)開發和管理的國際認證體系,旨在促進潛在爆炸性環境中使用的設備和部件的全球貿易。
IECEx系統的核心目標是建立一套全球公認的統一標準和認證程序。這消除了製造商爲不同市場獲得多個單獨認證的需要,從而減少了貿易的技術壁壘,並確保跨地區的產品安全一致性。

Becke Telcom專注於鐵路、隧道、石油和天然氣以及海事部門的工業防爆通信,提供具有集成PA、對講和呼叫功能的PAGA、SOS和IP電話。
