style="text-indent:25px">經(jīng)常會有人問電話交換機(jī)的作用是什么,簡單的說:程控交換機(jī)的作用就是　　1)共用外線 5個(gè)人或10個(gè)人共用一條外線。(起初這樣做的目的是為了節(jié)省電話月租，在90年代，固定電話月租很高，如一個(gè)公司有500員工，不可能沒人都申請一條直線，那樣的話，月租就是很大的一筆費(fèi)用。公司要讓大家每個(gè)人都有電話用，又想減少成本支出，買電話交換機(jī)就成了一種折中的方案。----每月把錢交給電信運(yùn)營商，我還不如省下月租，買個(gè)程控交換機(jī)，在一年之后，電話交換機(jī)的成本也就回來了，以后就是賺的了。　　2)管理功能 (現(xiàn)在大家都有電話用了，但是又有個(gè)問題：如果不能管理，電話費(fèi)又上來了。所以又要做一些限制，一些人允許打長途，一些人允許打市話，有些人只允許打內(nèi)部電話，泰州程控交換機(jī)廠家，所以第二點(diǎn)就是管理。　　3)內(nèi)部通話**(如果是本地電話，同事之間溝通，還需要向電信局交錢，泰州程控交換機(jī)廠家。所以在起初正是因?yàn)檫@個(gè)原因，也推動了電話交換機(jī)的普及?，F(xiàn)在電信運(yùn)營商推出了匯線通，集線通也可以內(nèi)部通話**。　　4)可以相互轉(zhuǎn)接(一個(gè)電話同甲同事講完后可以再轉(zhuǎn)給乙同事。匯線通，泰州程控交換機(jī)廠家，集線通也有此功能。　　5)其他功能(代接，代答，內(nèi)部廣播，保留音樂，電話計(jì)費(fèi)，電腦話務(wù)員，語音信箱，外接廣播。</p><div

1．程控交換機(jī)應(yīng)有良好的工作接地和保護(hù)接地.接地電阻值應(yīng)小于3Ω..每年都應(yīng)檢測并有檢測報(bào)告.. 2．程控交換機(jī)各控制板和外接電纜插口處應(yīng)安裝光電隔離器.. 3．電話電纜的屏蔽接地線應(yīng)和保護(hù)接地極連接良好.. 4．是程控交換機(jī)供電的交流電路(從配電室到交換機(jī))應(yīng)采用屏蔽電纜.屏蔽層應(yīng)和保護(hù)接地極連接良好.. 交換機(jī)遭雷擊損壞大多由雷電天氣在網(wǎng)線上產(chǎn)生的感應(yīng)電壓經(jīng)交換機(jī)信號端口竄入機(jī)內(nèi)造成，一般的整機(jī)防雷措施如裝設(shè)避雷針、機(jī)殼接地等無法解決這個(gè)問題。一般交換機(jī)信號端口內(nèi)部都設(shè)計(jì)有防雷擊電路，可以抵抗一般的輕微雷擊，但對大型雷電產(chǎn)生的雷擊則有些力不從心。為進(jìn)一步解決信號端口引進(jìn)的雷擊問題，可以采取以下一些措施： 1、外線盡量使用鎧裝電纜，并將鎧裝層妥善接地； 2、在外線與交換機(jī)端口之間加接防雷單元，具體措施有： ①串接防雷模塊， ②串接LC吸收單元， ③并接過壓保護(hù)元件， ④串接其它防雷保護(hù)電路。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">程控電話是指接入程控電話交換機(jī)的電話，程控電話交換機(jī)是利用電子計(jì)算機(jī)來控制的交換機(jī)，它以預(yù)先編好的程序來控制交換機(jī)的接續(xù)動作。此程控電話與一般機(jī)電式交換機(jī)的電話相比，具有接續(xù)速度快、業(yè)務(wù)功能多、交換效率高、聲音清晰、質(zhì)量可靠等優(yōu)點(diǎn)。程控交換機(jī)，也稱為程控?cái)?shù)字交換機(jī)或數(shù)字程控交換機(jī)，通常專指用于電話交換網(wǎng)的交換設(shè)備，它以計(jì)算機(jī)程序控制電話的接續(xù)。數(shù)字程控交換機(jī)分為長途交換機(jī)，本地交換機(jī)等。另外還有**于信令網(wǎng)和智能網(wǎng)的類型。數(shù)字程控交換機(jī)的基本功能為：用戶線接入，中繼接續(xù)，計(jì)費(fèi)，設(shè)備管理等。本地交換機(jī)自動檢測用戶的摘機(jī)動作，給用戶的電話機(jī)回送撥號音，接收話機(jī)的產(chǎn)生的脈沖信號或雙音多頻(DTMF)信號，然后完成從主叫到被叫號碼的接續(xù)(被叫號碼可能在同一個(gè)交換機(jī)也可能在不同的交換機(jī))。在接續(xù)完成后，交換機(jī)將保持連接，直到檢測出通信的一方掛機(jī)。程控電話交換機(jī)的作用是為中小企業(yè)構(gòu)架的內(nèi)部通訊網(wǎng)絡(luò)，幫助企業(yè)內(nèi)部與外界信息的傳遞與交流、生產(chǎn)調(diào)度與指令的傳達(dá)，避免走來走去或跑上跑下的麻煩、節(jié)省了相互通話的費(fèi)用(內(nèi)部電話無需支付電話費(fèi)、無月租費(fèi)、無承諾話費(fèi))，重要的在于為企業(yè)提高工作效率、又控制辦公話費(fèi)</p></p><br
