信息凈負(fù)荷位于STM-N幀中第1到第9行，第9×N+1到第270×N列，共9×261×N個(gè)字節(jié)。信息凈負(fù)荷是在STM-N幀結(jié)構(gòu)中存放將由STM-N傳送的各種用戶信息碼塊的地方。 </p> <p> 為了實(shí)時(shí)監(jiān)測(cè)貨物（打包的低速信號(hào)）在傳輸過程中是否有損壞，在將低速信號(hào)打包的過程中加入了通道開銷（POH）字節(jié)。POH作為凈負(fù)荷的一部分與信息碼塊一起裝載在STM-N這輛貨車上在SDH網(wǎng)中傳送，它負(fù)責(zé)對(duì)打包的貨物（低速信號(hào)）進(jìn)行通道性能監(jiān)視、管理和控制。 </p> <p> 2、段開銷（SOH） </p> <p> 段，相當(dāng)于一條大的傳輸通道，段開銷是為了保證信息凈負(fù)荷正常傳送所必須附加的網(wǎng)絡(luò)運(yùn)行、管理和維護(hù)（OAM）字節(jié)。也就是說SOH完成對(duì)貨物整體的監(jiān)控，POH是完成對(duì)某一件特定的貨物進(jìn)行監(jiān)控，當(dāng)然，SOH和POH還有一些其他管理功能。 </p> <p> 段開銷又分為再生段開銷（RSOH）和復(fù)用段開銷（MSOH），可分別對(duì)相應(yīng)的段層進(jìn)行監(jiān)控，二者的區(qū)別在于監(jiān)管的范圍不同。 </p> <p> 3、管理單元指針（AU-PTR） </p> <p> 管理單元指針位于STM-N幀中第4行的***到第9×N列，共9×N個(gè)字節(jié)。AU-PTR是用來指示信息凈負(fù)荷的***個(gè)字節(jié)在STM-N幀內(nèi)的準(zhǔn)確位置的指示符，以便接收端能根據(jù)這個(gè)位置指示符的值（指針值）準(zhǔn)確分離信息凈負(fù)荷。 </p><p style="text-indent:25px">SDH網(wǎng)絡(luò)是整個(gè)數(shù)字網(wǎng)的一部分，它的定時(shí)基準(zhǔn)應(yīng)是這個(gè)數(shù)字網(wǎng)的統(tǒng)一的定時(shí)基準(zhǔn)。時(shí)鐘同步，就是使通信網(wǎng)內(nèi)所有節(jié)點(diǎn)的時(shí)鐘頻率和相位都控制在預(yù)先確定的容差范圍內(nèi)，確保網(wǎng)內(nèi)各傳輸或交換節(jié)點(diǎn)的全部數(shù)字流正確有效地傳輸或交換，時(shí)鐘不同步，會(huì)在緩沖器中產(chǎn)生信息比特的溢出或取空，導(dǎo)致數(shù)字流的滑動(dòng)損傷，造成數(shù)據(jù)出錯(cuò)，影響正常運(yùn)行。電流差動(dòng)保護(hù)的關(guān)鍵是線路兩側(cè)保護(hù)之間的電流數(shù)據(jù)交換，當(dāng)復(fù)接數(shù)字通信設(shè)備時(shí)，同步時(shí)鐘的提取方式是一個(gè)非常重要的問題。本期新增節(jié)點(diǎn)均從線路側(cè)提取同步信號(hào)。SDH傳輸網(wǎng)是由不同類型的網(wǎng)元通過光纜線路的連接組成的。</p><div
