基本性能Features：
l 2U面板式安裝結構（1U=44.45mm），簡潔大方。Compact design, the panel merely occupies 2U rack room.
l 大型帶背光液晶顯示屏，實時時鐘顯示，觸摸按鍵、數(shù)字鍵盤、人性化操作。Large backlit LCD screen, digital keyboard, and is user-friendly operation.
l 采用2n線制的多線接線方式，每門分機電話線長度適于1500米以內。2N wiring installation, the maximum wiring distance is 1500 meters.
l 1～40門分機地址，可配接消防電話分機和消防電話插孔。Refer to different configuration, system may have 1 ～40 loop zones
l 通話自動錄音，可自動記錄通話地址和時間，在分機已被注冊的情況下，總機具有電話線路短路斷路故障判斷能力，并有聲光故障報警。Automatically record calls and calling information. All loops are real time monitored for open or short circuit.
l 消防電話分機摘機或插孔式消防電話分機插入消防電話插孔中可直接呼叫消防電話總機。總機可通過地址操作與多部分機呼叫和通話。消防電話分機、消防電話插孔都設有工作狀態(tài)指示燈。Calls to telephone exchange will be made when extensions off-hook or plug handset into jacks; throught digital keybroad, exchange is supported to call fews of extensions.
l 電話插孔HD230可多個并聯(lián)使用，線路末端電話插孔接入7.5kΩ/0.25W金屬膜電阻，可用于電話線路開路故障判斷。The 7.5KΩ/0.25W metal film resistor accessed in each loop zone is to detection the open or short circuit.
l 每路最多可并聯(lián)掛接電話插孔（HD230）60個或電話分機（HD210）4部。 System allows to connect 4 telephone extensions or 60 telephone jacks for each loop zone.
