style="text-indent:25px">設備功能數(shù)字程控交換機的基本功能主要為：用戶線接入，中繼接續(xù)，計費，設備管理等。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，接收話機產(chǎn)生的脈沖信號或雙音多頻（DTMF)信號，然後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)完成後，交換機將保持連接，直到檢測出通信的一方掛機。其中通話接續(xù)部分是利用交換機中的數(shù)字交換網(wǎng)絡，采用PCM方式實現(xiàn)數(shù)字交換的，控制部分是通過軟件由計算機來實現(xiàn)的。基本構(gòu)成電話交換機的主要任務是實現(xiàn)用戶間通話的接續(xù)?；緞澐譃閮纱蟛糠郑涸捖吩O備和控制設備，武漢程控交換機系統(tǒng)報價。話路設備主要包括各種接口電路（如用戶線接口和中繼線接口電路等)和交換 (或接續(xù)）網(wǎng)絡；控制設備在縱橫制交換機中主要包括標志器與記發(fā)器，而在程控交換機中，控制設備則為電子計算機，包括**處理器(CPU)，武漢程控交換機系統(tǒng)報價,存儲器和輸入 /輸出設備。程控交換機實質(zhì)上是采用計算機進行“存儲程序控制”的交換機，它將各種控制功能，方法編成程序，存入存儲器，武漢程控交換機系統(tǒng)報價，利用對外部狀態(tài)的掃描數(shù)據(jù)和存儲程序來控制，管理整個交換系統(tǒng)的工作。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="武漢程控交換機系統(tǒng)報價" src="http://tyunfile.71360.com/UpLoadFile/2019/7/17/14/636989701226092028_njdswy_1867050.png"></div><p style="text-indent:25px">優(yōu)越性 1、技術(shù)上的優(yōu)越性（1）能夠提供許多新的用戶服務功能，如縮位撥號、來電顯示、叫醒業(yè)務、呼叫轉(zhuǎn)移、呼叫等待等業(yè)務，不再是單一的語音業(yè)務了。（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。為適應交換機外部條件的變化，增加的新業(yè)務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小；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。</p><div
