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><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現(xiàn)分機(jī)與外線一對一的接入，實現(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，運行穩(wěn)定，壽命長（穩(wěn)定運行十年以上）。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、即時計費、實時監(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。邢臺程控交換機(jī)廠家</p><p
