1、技術(shù)上的優(yōu)越性（1）能夠提供許多新的用戶服務(wù)功能，如縮位撥號、來電顯示、叫醒業(yè)務(wù)、呼叫轉(zhuǎn)移、呼叫等待等業(yè)務(wù)，不再是單一的語音業(yè)務(wù)了。（2）維護管理方便，可靠性高。程控交換機可以通過故障診斷程序?qū)收线M行檢測和定位，以發(fā)生故障時緊急處理迅速及時，因此它在維護管理上和可靠性上帶來了好處。（3）靈活性大。為適應(yīng)交換機外部條件的變化，增加的新業(yè)務(wù)往往只需要改變軟件（程序和數(shù)據(jù)）就能滿足不同外部條件（如市話局、長話局等的不同需求）的需要。（4）便于利用電子器件的***成果，使整機技術(shù)上的先進性得到發(fā)揮。 2、經(jīng)濟上的優(yōu)越性（1）交換設(shè)備方面。體積小，采用電子器件大減小了交換機的體積，這樣占用機房的面積??；耗電省，用電子器件代替機械部件，**減低了能量消耗；成本低，隨著集成電路價格的減低，可以大幅度減低交換機成本。（2）線路設(shè)備方面。可以通過采用遠端用戶模塊方式節(jié)省用戶線，降低線路設(shè)備費用。（3）維護生產(chǎn)方面。由于檢測和診斷故障的自動化，減少了不少維護工作量，節(jié)省了維護人員。由于制造工藝簡單了，生產(chǎn)效率也提高了。河南程控交換機</p><div

1.安裝電話交換機好處作用之一------各辦公室共用外線一臺電話交換機可以使一、二條外線就分配給十幾或幾十個員工（或科室、部門）使用。為貴公司每一名員工安排一部分機，這樣即能節(jié)約費用，又節(jié)約人工的同時，對于外線打入者也會以zui快的速度與要聯(lián)系的人聯(lián)系。 2.安裝集團電話交換機好處作用之二------管理功能電話交換機可以限制，一些部門允許打長途，一些部門允許打市話，有些部門只允許打內(nèi)部電話，還可以管理監(jiān)控各辦公室的詳細話費清單。 3.安裝程控電話交換機好處作用之三------內(nèi)部通話** 分機內(nèi)部**通話，無需支付電話費、無月租費、無承諾話費。 4.安裝程控交換機好處作用之四------可以相互轉(zhuǎn)接外線電話打進來可通過分機轉(zhuǎn)接，而不用使員工跑來跑去接電話或來回找人接電話。程控交換機，全稱為存儲程序控制交換機（與之對應(yīng)的是布線邏輯控制交換機，簡稱布控交換機），也稱為程控數(shù)字交換機或數(shù)字程控交換機。通常專指用于電話交換網(wǎng)的交換設(shè)備，它以計算機程序控制電話的接續(xù)。程控交換機是利用現(xiàn)代計算機技術(shù)，完成控制、接續(xù)等工作的電話交換機。</p><p style="text-indent:25px"> 對電話程控交換機遭受雷擊的情況分析：***.電話程控交換機是由多塊功能電路板拼插組成.電路板上有許多功能集成塊、半導(dǎo)體元件及電感、電容、電阻.其**能集成塊中大量采用CMOS電路.工作電壓在0.7~5V..CMOS電路的過電壓能力弱.容易損壞.造成電路板甚至整個程控交換機系統(tǒng)故障..第二.由于電話交換機是很多電纜、電線的**點..電話分機線路多在幾十米至上百米的長度.涉及區(qū)域廣、范圍大.更易受雷擊.. 　　這樣．即使是感應(yīng)雷所形成的感應(yīng)過電壓對電話程控交換機都能形成威脅..雷擊在建筑物(機房或辦公樓)、設(shè)備(電話程控交換機)及電纜電路的附近發(fā)生；或閃電不直接對地放電.只是在距建筑物較近的云層和云層之間放電.閃電釋放電荷所形成的強電磁場.通過電話程控交換機的密集的網(wǎng)線、電源電路和數(shù)據(jù)傳輸電路中感應(yīng)生成過電壓。這種“過電壓”或?qū)㈦娫茨K.或?qū)?shù)據(jù)存儲器及微處理器、電話程控交換機用戶板擊壞。</p><p style="text-indent:25px">程控電話是指接入程控電話交換機的電話，程控電話交換機是利用電子計算機來控制的交換機，它以預(yù)先編好的程序來控制交換機的接續(xù)動作。此程控電話與一般機電式交換機的電話相比，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。程控交換機，也稱為程控數(shù)字交換機或數(shù)字程控交換機，通常專指用于電話交換網(wǎng)的交換設(shè)備，它以計算機程序控制電話的接續(xù)。數(shù)字程控交換機分為長途交換機，本地交換機等。另外還有**于信令網(wǎng)和智能網(wǎng)的類型。數(shù)字程控交換機的基本功能為：用戶線接入，中繼接續(xù)，計費，設(shè)備管理等。本地交換機自動檢測用戶的摘機動作，給用戶的電話機回送撥號音，接收話機的產(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交換機也可能在不同的交換機)。在接續(xù)完成后，交換機將保持連接，直到檢測出通信的一方掛機。程控電話交換機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，避免走來走去或跑上跑下的麻煩、節(jié)省了相互通話的費用(內(nèi)部電話無需支付電話費、無月租費、無承諾話費)，重要的在于為企業(yè)提高工作效率、又控制辦公話費淮南正規(guī)程控交換機</p><p
