style="text-indent:25px">數(shù)字程控交換機(jī)和模擬交換機(jī)相比，區(qū)別是：一、數(shù)字程控交換機(jī)通話間隔遠(yuǎn)、傳輸速度快、通話音質(zhì)清楚、誤碼少。而模擬交換機(jī)相對而言相差好幾倍。二、數(shù)字程控交換機(jī)全繩路無阻塞，也就是有多少對電話就可以同時有多少對電話通話。而模擬交換機(jī)有繩路線限制，當(dāng)交換機(jī)容量越少時它的通話繩路也就越少，通話量大時會造成死機(jī)。三、數(shù)字程控交換機(jī)接口豐盛、它可以接進(jìn)環(huán)路中繼、載波、2M等中繼、包含數(shù)字用戶的2B+D（PRI/7號信令），具備組網(wǎng)、局用機(jī)匯接功能。比如2M中繼接進(jìn)把交換機(jī)變成一臺虛擬網(wǎng)，就是在2M中繼中可以放入較多的電話號碼實(shí)現(xiàn)分機(jī)與外線一對一的接入，實(shí)現(xiàn)本地電話局的控制。這些功能模擬交換機(jī)是沒有的，宜春程控交換機(jī)報(bào)價(jià)行情。四、硬件系統(tǒng)，數(shù)字程控交換機(jī)采用的是時分電路，有強(qiáng)大的CPU控制功能，材質(zhì)和線路均采用高科技設(shè)計(jì)，運(yùn)行穩(wěn)定，宜春程控交換機(jī)報(bào)價(jià)行情，壽命長（穩(wěn)定運(yùn)行十年以上），宜春程控交換機(jī)報(bào)價(jià)行情。而模擬交換機(jī)采用了空分電路，控制部分是單片機(jī)芯片，線路簡單，材質(zhì)差，壽命短。五、數(shù)字程控交換機(jī)特色功能：內(nèi)含應(yīng)用軟件，具有參數(shù)設(shè)置、即時計(jì)費(fèi)、實(shí)時監(jiān)控、來電彈屏及小型呼叫中心功能等，而模擬交換機(jī)的應(yīng)用軟件只有調(diào)試功能，無法滿足中、大型企業(yè)的辦公需求。宜春程控交換機(jī)報(bào)價(jià)行情</p><div

1.安裝電話交換機(jī)好處作用之一------各辦公室共用外線一臺電話交換機(jī)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(jī)，這樣即能節(jié)約費(fèi)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(tuán)電話交換機(jī)好處作用之二------管理功能電話交換機(jī)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(xì)話費(fèi)清單。 3.安裝程控電話交換機(jī)好處作用之三------內(nèi)部通話** 分機(jī)內(nèi)部**通話，無需支付電話費(fèi)、無月租費(fèi)、無承諾話費(fèi)。 4.安裝程控交換機(jī)好處作用之四------可以相互轉(zhuǎn)接外線電話打進(jìn)來可通過分機(jī)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(jī)，全稱為存儲程序控制交換機(jī)（與之對應(yīng)的是布線邏輯控制交換機(jī)，簡稱布控交換機(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)。程控交換機(jī)是利用現(xiàn)代計(jì)算機(jī)技術(shù)，完成控制、接續(xù)等工作的電話交換機(jī)。晉中專業(yè)程控交換機(jī)</p><div

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??；耗電省，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(jià)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。由于制造工藝簡單了，生產(chǎn)效率也提高了。</p><p

對電話程控交換機(jī)遭受雷擊的情況分析：***.電話程控交換機(jī)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(jī)系統(tǒng)故障..第二.由于電話交換機(jī)是很多電纜、電線的**點(diǎn)..電話分機(jī)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..
