              電話交換機的發展歷程-深圳市金維通訊技術有限公司為您講述


              相信大家對于“科技成就夢想,網絡改變生活”這句話并不陌生吧。隨著Internet技術的不斷完善,我們的生活發生的巨大的變化,作為植入了很多網絡元素的通信行業也經歷了一場大的變革,從傳統的交換機演進到下一代融合型交換機。下面就讓我們一起來了解一下吧。

              自1876年美國貝爾發明了電話以來,隨著社會需求的日益增長和科技水平的不斷提高,電話交換機技術處于迅速的變革和發展之中。其歷程可分為三個階段:人工交換、機電交換和電子交換。

              一、1878~1892,人工交換機時代

              早在1878年就出現了人工交換機,它是借助話務員進行話務轉接分配,顯然其效率是很低的。

              二、1893年,機電交換時代

              隨著步進制的交換機問世,松下電話交換機標志著交換技術從人工時代邁入機電交換時代。隨著半導體器件和計算機技術的誕生與迅速發展,猛烈地沖擊著傳統的機電式交換結構,使之走向電子化。

              三、1965年,電子交換時代

              美國貝爾公司經過艱苦努力于1965年生產了世界上第一臺商用存儲程序控制的電子交換機(No.1 ESS),這一成果標志著電話交換機從機電時代躍入電子時代,使交換技術發生時代的變革。由于電子交換機具有體積小、速度快、便于提供有效而可靠的服務等優點,引起世界各國的極大興趣。在發展過程中相繼研制出各種類型的電子交換機。

              四、進入新世紀,軟交換開始流行

              軟交換的概念最早起源于美國。當時在企業網絡環境下,用戶采用基于以太網的電話交換系統,通過一套基于PC服務器的呼叫控制軟件(Call Manager、Call Server),實現PBX功能(IP PBX)。對于這樣一套設備,系統不需單獨鋪設網絡,而只通過與局域網共享就可實現管理與維護的統一,綜合成本遠低于傳統的PBX。由于企業網環境對設備的可靠性、計費和管理要求不高,主要用于滿足通信需求,設備門檻低,許多設備商都可提供此類解決方案,因此IP PBX應用獲得了一定的成功。受到IP PBX成功的啟發,為了提高網絡綜合運營效益,網絡的發展更加趨于合理、開放,更好的服務于用戶。業界提出了這樣一種思想:將傳統的交換設備部件化,分為呼叫控制與媒體處理,二者之間采用標準協議(MGCP、H248)且主要使用純軟件進行處理,于是,Softswitch(軟交換)技術應運而生。

              五、現在,下一代融合型交換機問世

              隨著企業的業務應用越來越傾向于服務化、本地化、個性化,企業不僅需要語音電話系統,還需要在各個分支機構搭建客服系統、遠程座員甚至UC(統一通訊平臺),而且多個系統之間的信息應當是同步、共享的。但是企業并不想為此付出高額而重復的設備和人員投資,在已有的傳統交換機上通過購買不同廠家的CTI中間件、錄音服務器、IP網關等等設備的方案而讓整個系統顯得笨重且難以維護,因此數據與語音融合、布署靈活(可分布可集中)、集中管理、統一維護的多功能系統才能為企業帶來高效的ROI(投資回報率),下一代融合型交換機正是在這樣的市場契機下誕生了!融合性交換機的核心是基于包交換的基礎上融合了電路交換和語音處理功能,并將數據語音集成功能融合到系統平臺中,它是一個集IP語音交換、交互式語音應答、自動話務分配、以及語音信箱、通話錄音、傳真功能、座席應用功能等融為一體的先進的交換機系統。從而一個平臺即可以同時作為IP辦公電話系統、呼叫中心系統、遠程/移動辦公系統和統一通訊平臺,松下電話交換機最大化地減少企業的重復投資,讓企業不再糾結于跨系統之間的數據同步、難維護等問題!
