電話機原理
電(dian)(dian)(dian)(dian)話(hua)通信是通過聲(sheng)(sheng)能與(yu)電(dian)(dian)(dian)(dian)能相互轉換、并利(li)用(yong)“電(dian)(dian)(dian)(dian)”這個媒介來傳輸(shu)語言的(de)一種通信技術。打電(dian)(dian)(dian)(dian)話(hua)時聲(sheng)(sheng)波(bo)作用(yong)于送(song)話(hua)器上產生(sheng)電(dian)(dian)(dian)(dian)流(liu),電(dian)(dian)(dian)(dian)流(liu)沿著線路傳達到(dao)對方電(dian)(dian)(dian)(dian)話(hua)機,再將電(dian)(dian)(dian)(dian)流(liu)轉化為聲(sheng)(sheng)波(bo)就完成了遠程通話(hua)。
電話機怎么安裝
首(shou)先要選好(hao)分(fen)(fen)線(xian)盒,通常(chang)選擇最近的(de)分(fen)(fen)線(xian)盒,然后選擇一(yi)根配號線(xian),在(zai)分(fen)(fen)線(xian)盒的(de)外(wai)面(mian)牽一(yi)根線(xian)到家里面(mian),將線(xian)接好(hao)電(dian)話,撥111確(que)定端(duan)(duan)口(kou)(kou)號,確(que)定端(duan)(duan)口(kou)(kou)號是(shi)否正(zheng)確(que),在(zai)外(wai)線(xian)找(zhao)到一(yi)個(ge)端(duan)(duan)口(kou)(kou),用專(zhuan)門的(de)跳線(xian)從內線(xian)的(de)一(yi)個(ge)端(duan)(duan)口(kou)(kou)接到外(wai)線(xian)那邊的(de)端(duan)(duan)口(kou)(kou)。最后一(yi)步就(jiu)是(shi)將保(bao)險單元插到外(wai)線(xian)的(de)端(duan)(duan)口(kou)(kou)。
如何選購電話機
首先要選用與當地交換機制式相適應的電話機,然后要考慮電話機的功能,比如免提揚聲、液晶顯示、錄音應答等功能;購買前還要檢查電話機的外觀質量是否合格,聲音是否清晰無噪聲,聲調是否正常等。建議選擇正規品牌電話機,質量有保障。
