高可用性和網絡彈性
M120N是功能強大的工業級路由器，提供強大的網絡處理能力和Multi-WAN連接性，專為實現網絡可靠性和不中斷連續通訊而設計。支持彈性的WAN連接，可以自動地轉換備援WAN介面，當主要的WAN介面失效，次要的WAN介面會自動備援連線，降低服務中斷的干擾。M120N也支援雙SIM卡應用，可實現無線通訊的相互備援。M120N具有四個Gigabit乙太網路端口，一個支援RS-232或RS-485的串行端口和802.11n AP，提供多樣本地介面滿足絕大多數的Smart Bus和M2M的應用需求。

專為工業環境與車載而設計
M120N能在攝氏負40度至60度(華氏負40度至140度)的環境溫度下穩定工作，允許輸入的直流電壓範圍自10至56伏特，可用於各種環境和應用。此外，M120N 也適於裝置在各種大小的車輛，並配置了點火感應(Ignition Sensing)，可自動感應車輛引擎發動狀況，當車輛熄火後會自動關機，以防止汽車電池能源耗盡。為實現簡單、可靠和高效的目標，簡潔、輕巧的設計結合高度彈性的安裝選項，以確保M120N可以輕鬆地安裝在任何地方。
