如圖像監(jiān)控、實時數(shù)據(jù)采集、實時控制、各種管理信息系統(tǒng)(MIS) 等，寧夏光傳輸設(shè)備SDH烽火CKU,原先采用窄帶數(shù)據(jù)網(wǎng)承載的業(yè)務(wù)也逐步轉(zhuǎn)移到寬帶數(shù)據(jù)網(wǎng)上。除此之外, 電力通信**網(wǎng)本身還具有一些特點: </p> <p> (1) 電力通信網(wǎng)基本上應(yīng)以光纖通信為主, 以微波通信作備份或補充。 </p> <p> (2) 光纖網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)復(fù)雜, 整個網(wǎng)絡(luò)節(jié)點數(shù)非常多, 需要傳輸設(shè)備有很強的組網(wǎng)和網(wǎng)絡(luò)管理能力,且對設(shè)備的可靠性要求非常高。 </p> <p> (3) 電力系統(tǒng)所敷設(shè)光纜通常芯數(shù)較少, 考慮到今后可能作為電信運營商, 應(yīng)盡量節(jié)約光纖通信系統(tǒng)所占用的光纖芯數(shù)。 </p> <p> (4) 為滿足整個電力部門目前和將來的所有通信需求, 需要做到話音、視頻和數(shù)據(jù)多網(wǎng)融合。 </p> <p> （5) 目前的業(yè)務(wù)接口需求主要有POTS、2W/4W、E&M、V.24、V.35，寧夏光傳輸設(shè)備SDH烽火CKU、ISDN、E1、E3/T 3、10Mb/100Mb以太網(wǎng)接口等, 未來的業(yè)務(wù)需求大,多基于寬帶數(shù)據(jù)網(wǎng)。采用基于SDH 和MSTP，寧夏光傳輸設(shè)備SDH烽火CKU, 可使調(diào)度網(wǎng)實現(xiàn)計算機網(wǎng)絡(luò)的遠程互聯(lián), 在SDH平臺上實現(xiàn)以太網(wǎng)業(yè)務(wù)傳送功能, 從而實現(xiàn)二網(wǎng)合一,

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)整機理復(fù)雜。 </p> <p>
