SDH網(wǎng)絡(luò)的常見網(wǎng)元和功能 </p> <p> 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，通過不同的網(wǎng)元完成SDH網(wǎng)的傳送功能：上/下業(yè)務(wù)、交叉連接業(yè)務(wù)、網(wǎng)絡(luò)故障自愈等。下面我們講述SDH網(wǎng)中常見網(wǎng)元的特點(diǎn)和基本功能。 </p> <p> TM——終端復(fù)用器 </p> <p> 終端復(fù)用器用在網(wǎng)絡(luò)的終端站點(diǎn)上，例如一條鏈的兩個(gè)端點(diǎn)上，它是一個(gè)雙端口器件。它的作用是將支路端口的低速信號復(fù)用到線路端口的高速信號STM-N中，或從STM-N的信號中分出低速支路信號。請注意它的線路端口輸入/輸出一路STM-N信號，而支路端口卻可以輸出/輸入多路低速支路信號。在將低速支路信號復(fù)用進(jìn)STM-N幀（將低速信號復(fù)用到線路）上時(shí)，有一個(gè)交叉的功能，例如：可將支路的一個(gè)STM-1信號復(fù)用進(jìn)線路上的STM-16信號中的任意位置上，也就是指復(fù)用在1~16個(gè)STM-1的任一個(gè)位置上。將支路的2Mbit/s信號可復(fù)用到一個(gè)STM-1中63個(gè)VC12的任一個(gè)位置上去。對于華為設(shè)備，TM的線路端口（光口）一般以西向端口默認(rèn)表示的。樹形網(wǎng)絡(luò)拓?fù)淇煽闯墒擎溞瓮負(fù)浜托切瓮負(fù)涞慕Y(jié)合。</p><div
