src="http://tyunfile.71360.com/UpLoadFile/2019/7/17/14/636989701226092028_njdswy_1867050.png"></div><p 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(duì)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(duì)電話就可以同時(shí)有多少對(duì)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(shí)它的通話繩路也就越少，通話量大時(shí)會(huì)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(hào)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(tái)虛擬網(wǎng)，就是在2M中繼中可以放入較多的電話號(hào)碼實(shí)現(xiàn)分機(jī)與外線一對(duì)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。四、硬件系統(tǒng)，數(shù)字程控交換機(jī)采用的是時(shí)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，壽命長（穩(wěn)定運(yùn)行十年以上）。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(shí)計(jì)費(fèi)、實(shí)時(shí)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。</p><div
