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)時監(jiān)測貨物（打包的低速信號）在傳輸過程中是否有損壞，在將低速信號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)對打包的貨物（低速信號）進(jìn)行通道性能監(jiān)視、管理和控制。 </p> <p> 2，云南全新光傳輸設(shè)備烽火8路帶交換功能快速以太網(wǎng)處理板、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完成對貨物整體的監(jiān)控，POH是完成對某一件特定的貨物進(jìn)行監(jiān)控，云南全新光傳輸設(shè)備烽火8路帶交換功能快速以太網(wǎng)處理板，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個字節(jié)。AU-PTR是用來指示信息凈負(fù)荷的***個字節(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)這個位置指示符的值（指針值）準(zhǔn)確分離信息凈負(fù)荷。同時也使網(wǎng)絡(luò)運(yùn)行靈活，云南全新光傳輸設(shè)備烽火8路帶交換功能快速以太網(wǎng)處理板、安全、可靠，使網(wǎng)絡(luò)的功能非常齊全和多樣化；云南全新光傳輸設(shè)備烽火8路帶交換功能快速以太網(wǎng)處理板</p><div

SDH的缺點(diǎn)， </p> <p> 1，頻帶利用率低。 </p> <p> 可靠性和有效性是矛盾的，增加了有效性必將降低可靠性，增加了可靠性也會相應(yīng)的使有效性降低。例如，收音機(jī)的選擇性增加，可選的電臺就增多，這樣就提高了選擇性。但是，由于這時頻帶相應(yīng)的會變窄，必然會使音質(zhì)下降，也就降低了可靠性。 </p> <p> 2，指針調(diào)整機(jī)理復(fù)雜。 </p> <p>

<p> 3，軟件的大量使用對系統(tǒng)的安全性的影響。 </p> <p> 在***無處不在的***，軟件的的大量使用，很容易受到***的破壞，加上人為操作，軟件故障，對系統(tǒng)的影響也是致命的。 </p> <p> <br /> 分/插復(fù)用器用于SDH傳輸網(wǎng)絡(luò)的轉(zhuǎn)接站點(diǎn)處。</p><div
