1、可靠性

要求各種電源設(she)備、各種開關(guan)(guan)、轉換開關(guan)(guan)和其他的配電設(she)備必須非常可(ke)靠，具有很高(gao)的平均無故障時(shi)間指標(biao)。在設(she)計(ji)通信電源系(xi)統時(shi)力求簡單，采取消除(chu)或減(jian)少單點故障的設(she)計(ji)方法。

2、功能性

要求各(ge)種(zhong)(zhong)電(dian)(dian)(dian)(dian)源設(she)備必須能(neng)穩定供電(dian)(dian)(dian)(dian)，各(ge)項輸(shu)出(chu)指標滿足(zu)質(zhi)量要求。供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓過高會引(yin)起通(tong)(tong)(tong)信負(fu)載設(she)備元器(qi)件損(sun)壞，供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓過低又會影(ying)響通(tong)(tong)(tong)信系統(tong)的正常(chang)運行。直流供電(dian)(dian)(dian)(dian)系統(tong)的衡重雜音(yin)電(dian)(dian)(dian)(dian)壓過高會影(ying)響電(dian)(dian)(dian)(dian)話通(tong)(tong)(tong)話質(zhi)量；脈動(dong)電(dian)(dian)(dian)(dian)壓過高會使數據通(tong)(tong)(tong)信設(she)備的誤碼率(lv)增加。UPS交流不間斷電(dian)(dian)(dian)(dian)源應能(neng)抑制市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源的各(ge)種(zhong)(zhong)干擾，干擾可能(neng)引(yin)起互聯(lian)網傳輸(shu)速率(lv)下(xia)降、數據丟失等，甚至導致網絡癱瘓。

3、可維修性

通(tong)(tong)信(xin)(xin)電(dian)源(yuan)系(xi)統的(de)(de)(de)設計必(bi)須使(shi)所有電(dian)源(yuan)系(xi)統元件能夠在(zai)通(tong)(tong)信(xin)(xin)系(xi)統正常供電(dian)的(de)(de)(de)情(qing)況下(xia)進(jin)行(xing)維護，一(yi)般稱為“同(tong)時維護”，即通(tong)(tong)信(xin)(xin)電(dian)源(yuan)系(xi)統的(de)(de)(de)一(yi)部(bu)分設備在(zai)正常運行(xing)的(de)(de)(de)同(tong)時對另一(yi)部(bu)分電(dian)源(yuan)設備進(jin)行(xing)維護。

4、故障容限

通信電(dian)源系(xi)統必(bi)須具有抗故障(zhang)(zhang)的(de)能力，做到電(dian)源系(xi)統的(de)任何(he)元件出現故障(zhang)(zhang)都不(bu)會影響(xiang)正常供(gong)電(dian)和通信負載設備的(de)正常運行，而(er)且整個配電(dian)系(xi)統也必(bi)須有抗故障(zhang)(zhang)的(de)能力，從(cong)而(er)可以彌補不(bu)可避免(mian)的(de)負載故障(zhang)(zhang)和人為操作(zuo)錯誤造(zao)成的(de)影響(xiang)。
