1）SDH傳輸系統(tǒng)在國際上有統(tǒng)一的幀結構數(shù)字傳輸標準速率和標準的光路接口，使網(wǎng)管系統(tǒng)互通，因此有很好的橫向兼容性，它能與現(xiàn)有的PDH完全兼容，并容納各種新的業(yè)務信號，重慶光傳輸設備價格烽火IBAS 180，形成了全球統(tǒng)一的數(shù)字傳輸體制標準，提高了網(wǎng)絡的可靠性； </p> <p> （2）SDH接入系統(tǒng)的不同等級的碼流在幀結構凈負荷區(qū)內的排列非常有規(guī)律，而凈負荷與網(wǎng)絡是同步的，它利用軟件能將高速信號一次直接分插出低速支路信號，實現(xiàn)了一次復用的特性，克服了PDH準同步復用方式對全部高速信號進行逐級分解然后再生復用的過程，重慶光傳輸設備價格烽火IBAS 180，重慶光傳輸設備價格烽火IBAS 180，由于**簡化了DXC，減少了背靠背的接口復用設備，改善了網(wǎng)絡的業(yè)務傳送透明性； </p> <p> （3）由于采用了較先進的分插復用器（ADM）、數(shù)字交叉連接（DXC）、網(wǎng)絡的自愈功能和重組功能就顯得非常強大，具有較強的生存率。因SDH幀結構中安排了信號的5％開銷比特，它的網(wǎng)管功能顯得特別強大，并能統(tǒng)一形成網(wǎng)絡管理系統(tǒng)，為網(wǎng)絡的自動化、智能化、信道的利用率以及降低網(wǎng)絡的維管費和生存能力起到了積極作用；

對于大多數(shù)專網(wǎng)，在目前的技術條件下，則應利用公眾網(wǎng)實現(xiàn)企業(yè)或專業(yè)部門的通信需求。利用公眾網(wǎng)滿足專業(yè)部門的需求具有各種不同的方式。如租用公眾網(wǎng)的光芯或傳輸容量，配置自己的交換設備。這就免除了**困難的光纜輔設工程，比較適用于具有大規(guī)模用戶的企業(yè)。又如委托公眾網(wǎng)**為本企業(yè)或部門使用的虛擬**網(wǎng)，它所提供的功能和容量完全按照用戶的要求進行，這就免除了全部的投資風險和維護工作，應用機動靈活，使用部門可以專心致力于其本行業(yè)的業(yè)務工作。

DXC可將輸入的m路STM-N信號交叉連接到輸出的n路STM-N信號上，上圖表示有m條入光纖和n條出光纖。DXC的**是交叉連接，功能強的DXC能完成高速（例STM-16）信號在交叉矩陣內的低級別交叉（例如VC12級別的交叉）。 </p> <p> 通常用DXCm/n來表示一個DXC的類型和性能（注m≥n），m表示可接入DXC的比較高速率等級，n表示在交叉矩陣中能夠進行交叉連接的比較低速率級別。m越大表示DXC的承載容量越大；n越小表示DXC的交叉靈活性越大。 </p> <p> <br /> 這些系統(tǒng)的所有信息傳輸都必須由通信系統(tǒng)提供通道。</p><div style="width:100%;text-align:
