style="text-indent:25px">億聯(lián)IP電話結(jié)構(gòu)以及處理過程電話結(jié)構(gòu)采用電路交換的傳統(tǒng)語音電話，它***使用的是PCM語音編碼技術(shù)，即用戶側(cè)傳輸?shù)氖悄M信號，而局間傳輸?shù)氖菙?shù)字信號，從而模擬信號到局間數(shù)字信號采用PCM編碼方式，也就是脈沖編碼調(diào)制。PCM包括采樣，連云港億聯(lián)IP話機(jī)、量化、編碼這幾個過程，而且每次通話的時候都要在局端建立一個獨(dú)享的信道，在通話過程中始終占據(jù)此信道，信道的數(shù)量決定了億聯(lián)IP電話的通話的路數(shù)，此PCM編碼雖然語音質(zhì)量高。億聯(lián)IP電話的電弧是在基于IP的分組網(wǎng)絡(luò)上傳輸語音，將模擬的語音信號轉(zhuǎn)換為數(shù)字語音分組，采用存儲轉(zhuǎn)發(fā)的方法，以分組的形式在面向無連接的分組網(wǎng)絡(luò)上傳輸，這就是分組語音技術(shù)。他的特點(diǎn)是占用帶寬小，網(wǎng)絡(luò)利用率高，連云港億聯(lián)IP話機(jī)，通過一些技術(shù)手段還會使語音質(zhì)量有較大的提升，能夠滿足客戶的需求，所以這也就是它成為全國銷量**的億聯(lián)IP電話的原因。億聯(lián)IP電話對語音的處理流程是在發(fā)送端首先將模擬信號轉(zhuǎn)換為數(shù)字信號，轉(zhuǎn)換需要采用一定的語音編碼算法對語音信號進(jìn)行處理，連云港億聯(lián)IP話機(jī)，例如G729等等。在接收端，首先利用緩沖器來調(diào)節(jié)網(wǎng)絡(luò)產(chǎn)生的抖動，然后經(jīng)過***器將語音分組解壓后，***還原為模擬語音信號。連云港億聯(lián)IP話機(jī)</p><div

style="text-indent:25px">PHONE-PHONE的技術(shù)方案比較適合大型骨干型型電信語音企業(yè)的運(yùn)作模式，它把億聯(lián)IP電話工作的幾個步驟，皆放到系統(tǒng)的局端來處理，使用戶感覺不到是在使用億聯(lián)IP電話還認(rèn)為是普通電話，當(dāng)然由于IP網(wǎng)絡(luò)的維護(hù)簡單。而且現(xiàn)在所有的運(yùn)營商在骨干網(wǎng)配置上都采用億聯(lián)IP電話。在通話過程中，從技術(shù)的角度看，IP電話的工作過程包括幾下的步驟： 1、語音的數(shù)字化：發(fā)話端的模擬信號經(jīng)過PSTN發(fā)送到發(fā)端的IP網(wǎng)關(guān)上，然后利用數(shù)字處理設(shè)備，例如PCM，對語音進(jìn)行數(shù)字化。 2、數(shù)據(jù)壓縮：數(shù)據(jù)壓縮系統(tǒng)分析數(shù)字化后的信號，判斷信號里包含的額是語音、噪音還是語音空隙，然后丟掉噪音和語音空隙信號進(jìn)行壓縮。 3、數(shù)據(jù)打包：由于收集語音數(shù)據(jù)以及壓縮過程需要一些時間，就是時間延遲，為了能保證數(shù)據(jù)分塊傳輸，則必須進(jìn)行打包，且打包時加進(jìn)一些協(xié)議信息，例如每個數(shù)據(jù)包中應(yīng)該包含一個目的地址，包順序號，以及數(shù)據(jù)校驗(yàn)信息等。 4、解包以及解壓縮：億聯(lián)IP電話的每個包當(dāng)?shù)竭_(dá)目的地主機(jī)，就是網(wǎng)關(guān)、服務(wù)器或者用戶時，檢查該包的序號并將其放到正確的位置，然后利用解壓縮算法來盡量恢復(fù)原始信號數(shù)據(jù)。連云港億聯(lián)IP話機(jī)</p><div style="width:100%;text-align:
