基本性能(neng)Features：
l 2U面板式安(an)裝結構（1U=44.45mm），簡潔大方(fang)。Compact design, the panel merely occupies 2U rack room.
l 大型帶背光液晶顯示屏，實時時鐘(zhong)顯示，觸摸按鍵(jian)、數字鍵(jian)盤、人(ren)性(xing)化操作。Large backlit LCD screen, digital keyboard, and is user-friendly operation.
l 采用2n線(xian)(xian)制的(de)多線(xian)(xian)接線(xian)(xian)方(fang)式(shi)，每門(men)分機電話線(xian)長度適于(yu)1500米以內。2N wiring installation, the maximum wiring distance is 1500 meters.
l 1～40門分(fen)機地址(zhi)，可配接消防電話分(fen)機和消防電話插孔(kong)。Refer to different configuration, system may have 1 ～40 loop zones
l 通話(hua)自(zi)動錄音，可自(zi)動記錄通話(hua)地址和時間(jian)，在分機已被(bei)注(zhu)冊的情況下，總機具(ju)有電(dian)話(hua)線(xian)路(lu)(lu)短路(lu)(lu)斷路(lu)(lu)故障(zhang)判斷能力，并(bing)有聲光故障(zhang)報警。Automatically record calls and calling information. All loops are real time monitored for open or short circuit.
l 消(xiao)(xiao)防(fang)電(dian)話(hua)(hua)分機(ji)(ji)摘(zhai)機(ji)(ji)或(huo)插孔式消(xiao)(xiao)防(fang)電(dian)話(hua)(hua)分機(ji)(ji)插入(ru)消(xiao)(xiao)防(fang)電(dian)話(hua)(hua)插孔中可直接(jie)呼叫消(xiao)(xiao)防(fang)電(dian)話(hua)(hua)總(zong)機(ji)(ji)。總(zong)機(ji)(ji)可通過地址操(cao)作與多部(bu)分機(ji)(ji)呼叫和通話(hua)(hua)。消(xiao)(xiao)防(fang)電(dian)話(hua)(hua)分機(ji)(ji)、消(xiao)(xiao)防(fang)電(dian)話(hua)(hua)插孔都設有工作狀態指示燈(deng)。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(dian)話插孔HD230可多個并聯使用，線路(lu)末端電(dian)話插孔(kong)接入7.5kΩ/0.25W金屬膜電阻，可(ke)用于(yu)電話線路(lu)開路(lu)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(mei)路(lu)最多可并聯掛接電話插孔(kong)（HD230）60個(ge)或(huo)電話分(fen)機(ji)（HD210）4部。 System allows to connect 4 telephone extensions or 60 telephone jacks for each loop zone.
