程(cheng)(cheng)(cheng)控(kong)(kong)(kong)(kong)交(jiao)(jiao)換(huan)(huan)機(ji)(ji)通常專指用于電(dian)電(dian)話(hua)(hua)交(jiao)(jiao)換(huan)(huan)網的交(jiao)(jiao)換(huan)(huan)設(she)備,它(ta)以(yi)計(ji)算(suan)機(ji)(ji)程(cheng)(cheng)(cheng)序控(kong)(kong)(kong)(kong)制(zhi)(zhi)電(dian)話(hua)(hua)的接(jie)(jie)續(xu)。程(cheng)(cheng)(cheng)控(kong)(kong)(kong)(kong)交(jiao)(jiao)換(huan)(huan)機(ji)(ji)是(shi)利(li)用現(xian)(xian)代計(ji)算(suan)機(ji)(ji)技術,完成(cheng)控(kong)(kong)(kong)(kong)制(zhi)(zhi)、接(jie)(jie)續(xu)等(deng)工作(zuo)的電(dian)話(hua)(hua)交(jiao)(jiao)換(huan)(huan)機(ji)(ji)。電(dian)話(hua)(hua)交(jiao)(jiao)換(huan)(huan)機(ji)(ji)的主要(yao)任(ren)務是(shi)實現(xian)(xian)用戶間通話(hua)(hua)的接(jie)(jie)續(xu)。基本劃分為(wei)兩(liang)大部(bu)分:話(hua)(hua)路設(she)備和控(kong)(kong)(kong)(kong)制(zhi)(zhi)設(she)備。話(hua)(hua)路設(she)備主要(yao)包括(kuo)各種接(jie)(jie)口電(dian)路(如用戶線(xian)(xian)接(jie)(jie)口和中(zhong)繼線(xian)(xian)接(jie)(jie)口電(dian)路等(deng))和交(jiao)(jiao)換(huan)(huan)(或接(jie)(jie)續(xu))網絡;控(kong)(kong)(kong)(kong)制(zhi)(zhi)設(she)備在(zai)縱橫(heng)制(zhi)(zhi)交(jiao)(jiao)換(huan)(huan)機(ji)(ji)中(zhong)主要(yao)包括(kuo)標志器(qi)(qi)與記發器(qi)(qi),而在(zai)程(cheng)(cheng)(cheng)控(kong)(kong)(kong)(kong)交(jiao)(jiao)換(huan)(huan)機(ji)(ji)中(zhong),控(kong)(kong)(kong)(kong)制(zhi)(zhi)設(she)備則為(wei)電(dian)子計(ji)算(suan)機(ji)(ji),包括(kuo)中(zhong)央處(chu)理器(qi)(qi)(CPU),存儲器(qi)(qi)和輸(shu)(shu)入/輸(shu)(shu)出設(she)備。
1、技術上的優越(yue)性
(1)能夠提(ti)供(gong)許(xu)多新的(de)用戶(hu)服(fu)務(wu)功能,如(ru)縮位撥(bo)號、來電顯示(shi)、叫(jiao)醒業務(wu)、呼(hu)叫(jiao)轉(zhuan)移、呼(hu)叫(jiao)等待等業務(wu),不(bu)再是單一(yi)的(de)語音業務(wu)了(le)。
(2)維護(hu)管理方便,可靠性(xing)高。程(cheng)(cheng)控交換機可以通過故障診斷程(cheng)(cheng)序對故障進行檢(jian)測(ce)和(he)定(ding)位,以發生(sheng)故障時緊急處理迅速及時,因此它在維護(hu)管理上(shang)和(he)可靠性(xing)上(shang)帶來了(le)好處。
(3)靈活(huo)性大。為適應交(jiao)換(huan)機外(wai)部(bu)條(tiao)件的變化(hua),增加的新業務往往只需(xu)要(yao)改變軟件(程序(xu)和數據)就能滿足不(bu)同(tong)外(wai)部(bu)條(tiao)件(如(ru)市話(hua)局、長(chang)話(hua)局等的不(bu)同(tong)需(xu)求)的需(xu)要(yao)。
(4)便(bian)于利用電子器件的(de)新成果,使整(zheng)機技術上的(de)先進性得到(dao)發揮。
2、經濟上的(de)優越性
(1)交換(huan)設(she)備方面。體積(ji)小,采用(yong)電子(zi)器件(jian)大減(jian)小了交換(huan)機的體積(ji),這(zhe)樣(yang)占用(yong)機房的面積(ji)小;耗電省,用(yong)電子(zi)器件(jian)代替(ti)機械部件(jian),大大減(jian)低(di)了能量消耗;成(cheng)本低(di),隨著集成(cheng)電路價(jia)格的減(jian)低(di),可以(yi)大幅(fu)度(du)減(jian)低(di)交換(huan)機成(cheng)本。
(2)線路設備方(fang)面。可以通過采用(yong)遠(yuan)端用(yong)戶(hu)模塊方(fang)式節省用(yong)戶(hu)線,降低線路設備費用(yong)。
(3)維護(hu)生產(chan)方面(mian)。由于(yu)(yu)檢測和診斷故(gu)障(zhang)的自動化,減少(shao)了(le)不少(shao)維護(hu)工作量,節省了(le)維護(hu)人員(yuan)。由于(yu)(yu)制造工藝(yi)簡單(dan)了(le),生產(chan)效率(lv)也提高了(le)
