基本性能Features：
l 2U面板式安(an)裝結構(gou)（1U=44.45mm），簡潔大方。Compact design, the panel merely occupies 2U rack room.
l 大型帶背(bei)光液(ye)晶顯(xian)示屏，實時時鐘顯(xian)示，觸摸按鍵、數字鍵盤、人性化操作(zuo)。Large backlit LCD screen, digital keyboard, and is user-friendly operation.
l 采(cai)用2n線制的多線接線方(fang)式，每門分(fen)機(ji)電話(hua)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(hua)分機和消防電話(hua)插孔。Refer to different configuration, system may have 1 ～40 loop zones
l 通話(hua)(hua)自動錄音(yin)，可(ke)自動記錄通話(hua)(hua)地(di)址(zhi)和時(shi)間，在分機(ji)已(yi)被注冊的情(qing)況下(xia)，總機(ji)具有電話(hua)(hua)線路短路斷路故障判斷能力，并有聲光(guang)故障報(bao)警。Automatically record calls and calling information. All loops are real time monitored for open or short circuit.
l 消(xiao)防(fang)電話(hua)(hua)分(fen)(fen)機(ji)摘機(ji)或插(cha)孔(kong)式消(xiao)防(fang)電話(hua)(hua)分(fen)(fen)機(ji)插(cha)入消(xiao)防(fang)電話(hua)(hua)插(cha)孔(kong)中(zhong)可直接呼叫消(xiao)防(fang)電話(hua)(hua)總(zong)(zong)機(ji)。總(zong)(zong)機(ji)可通過地址(zhi)操作(zuo)與多部分(fen)(fen)機(ji)呼叫和(he)通話(hua)(hua)。消(xiao)防(fang)電話(hua)(hua)分(fen)(fen)機(ji)、消(xiao)防(fang)電話(hua)(hua)插(cha)孔(kong)都(dou)設(she)有工作(zuo)狀態指示(shi)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(hua)插孔HD230可多個并聯使(shi)用，線路末端(duan)電話插孔接入7.5kΩ/0.25W金屬膜電阻，可用于電話線路(lu)開路(lu)故障判(pan)斷(duan)。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(bing)聯掛(gua)接電話(hua)插孔（HD230）60個或電話(hua)分(fen)機（HD210）4部。 System allows to connect 4 telephone extensions or 60 telephone jacks for each loop zone.
