5個人或10個人共用一條外線。(起初這樣做的目的是為了節(jié)省電話月租，在90年代，固定電話月租很高，如一個公司有500員工，不可能沒人都申請一條直線，那樣的話，月租就是很大的一筆費(fèi)用。公司要讓大家每個人都有電話用，又想減少成本支出，買電話交換機(jī)就成了一種折中的方案。----每月把錢交給電信運(yùn)營商，我還不如省下月租，買個程控交換機(jī)，在一年之后，電話交換機(jī)的成本也就回來了，以后就是賺的了。　　2)管理功能 (現(xiàn)在大家都有電話用了，但是又有個問題：如果不能管理，電話費(fèi)又上來了。所以又要做一些限制，一些人允許打長途，一些人允許打市話，有些人只允許打內(nèi)部電話，所以第二點(diǎn)就是管理。　　3)內(nèi)部通話**(如果是本地電話，同事之間溝通，還需要向電信局交錢。所以在起初正是因為這個原因，也推動了電話交換機(jī)的普及?，F(xiàn)在電信運(yùn)營商推出了匯線通，集線通也可以內(nèi)部通話**。　　4)可以相互轉(zhuǎn)接(一個電話同甲同事講完后可以再轉(zhuǎn)給乙同事。匯線通，集線通也有此功能。　　5)其他功能(代接，代答，內(nèi)部廣播，保留音樂，電話計費(fèi)，電腦話務(wù)員，語音信箱，外接廣播。邵陽程控交換機(jī)通訊設(shè)備方案</p><div

src="http://tyunfile.71360.com/UpLoadFile/2019/7/17/14/636989701226871328_njdswy_4837658.png"></div><p style="text-indent:25px"> 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.. 　　這樣．即使是感應(yīng)雷所形成的感應(yīng)過電壓對電話程控交換機(jī)都能形成威脅..雷擊在建筑物(機(jī)房或辦公樓)、設(shè)備(電話程控交換機(jī))及電纜電路的附近發(fā)生；或閃電不直接對地放電.只是在距建筑物較近的云層和云層之間放電.閃電釋放電荷所形成的強(qiáng)電磁場.通過電話程控交換機(jī)的密集的網(wǎng)線、電源電路和數(shù)據(jù)傳輸電路中感應(yīng)生成過電壓。這種“過電壓”或?qū)㈦娫茨K.或?qū)?shù)據(jù)存儲器及微處理器、電話程控交換機(jī)用戶板擊壞。</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(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、即時計費(fèi)、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。</p><p style="text-indent:25px">程控電腦交換機(jī)，集團(tuán)電腦交換機(jī)，電話交換機(jī)系統(tǒng) 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)），也稱為程控數(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)代計算機(jī)技術(shù)，完成控制、接續(xù)等工作的電話交換機(jī)。溫州質(zhì)量程控交換機(jī)</p><p style="text-indent:25px">濰坊質(zhì)量程控交換機(jī)</p><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。濰坊質(zhì)量程控交換機(jī)</p><p
