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(hù)管理方便，可靠性高。程控交換機(jī)可以通過故障診斷程序?qū)收线M(jìn)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(hù)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(jī)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，長治程控交換機(jī)維修、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(jī)技術(shù)上的先進(jìn)性得到發(fā)揮。 2、經(jīng)濟(jì)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(jī)的體積，這樣占用機(jī)房的面積小；耗電**治程控交換機(jī)維修，用電子器件代替機(jī)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(jī)成本。（2）線路設(shè)備方面?？梢酝ㄟ^采用遠(yuǎn)端用戶模塊方式節(jié)省用戶線，降低線路設(shè)備費(fèi)用。（3）維護(hù)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(hù)工作量，節(jié)省了維護(hù)人員，長治程控交換機(jī)維修。由于制造工藝簡單了，生產(chǎn)效率也提高了。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="長治程控交換機(jī)維修" src="http://tyunfile.71360.com/UpLoadFile/2019/7/17/14/636989701226092028_njdswy_1867050.png"></div><p style="text-indent:25px">防雷擊可采取以下措施： 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問題。一般交換機(jī)信號端口內(nèi)部都設(shè)計有防雷擊電路，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:
