  1. Along with the technology mature in the soft switching and media gateway, the narrow band access equipment will be integrated the function of media gateway. users may access directly to the broadband ip man through twisted cabling or wireless base station. dial - up server will also be replaced by the media gateway, narrow band dial - up users will be diverted to broadband ip man at the access network

    隨著軟交換和媒體網關技術的成熟,在窄帶接入層設備上將綜合媒體網關的功能,用戶通過雙絞線或無線基站接入后,可以通過媒體網關直接接入寬帶ip城域網,撥號服務器也將大量被媒體網關取代,窄帶用戶撥號上網將在接入網被分流至寬帶ip城域網。
  2. Media gatewaytdmatm integrated access equipment is the main way of narrow band and data private line access. users may access fixed telephone network and dial - up access braodband man through twisted cable ; users may access broadband data network through adsl or ddn, or fr, etc ; mobile comminication users may access 2g or 3g mobile communication network through base station equipment and wireless gateway

    媒體網關tdmatm綜合接入設備主要是窄帶和數據專線接入方式,用戶通過雙絞線可以接入固定電話網以及撥號接入寬帶ip城域網;用戶通過adsl或ddn 、 fr等可接入寬帶基礎數據網;移動通信用戶通過基站設備和無線網關可接入第二代或第三代移動通信網。
  3. With the broadband network, it is possible to replace the free of charge operational mode of the conventional narrow - band internet services with the charged mode

    從寬帶開始有可能擯棄原來傳統窄帶因特網業務的「免費」的商業模式,進入收費運營的模式。
  4. In the first place, start with theoretic model of distributed fbg strain - sensing network, sensing principle of fiber bragg grating is analyzed and sensing model created. on the basis of analyzing advantages and disadvantages of several familiar multiplexing and demodulation techniques, a mixture multiplexing method that combines optical frequency domain reflectometry ( ofdr ) and wavelength division multiplexing ( wdm ) is proposed to address fbg sensing array. at the same time, tunable narrow - band light source, which is composed of wide - band light source and tunable optical filter, is adopted to demodulate multiplex signals

    首先,論文從分散式光纖光柵應變傳感網路的理論模型入手,分析了光纖布拉格光柵的傳感機理,建立光纖光柵應變傳感模型;在分析比較了常見幾種復用技術和信號解調技術的優缺點基礎上,提出應用光頻域反射復用技術和波分復用技術相結合的混合復用方法來解決光纖光柵應變傳感網路的尋址問題,採用由寬帶光源和可調諧光濾波器組成的可調諧窄帶光源來解調復用信號,通過理論分析和實驗研究證實了系統方案的可行性。
  5. Access layer network will focus on the development of broadband access. when large demand for the divertion of the narrow band ip dial - up services, it is suggested to adopt the gateway mode

    ?接入層網路重點發展寬帶接入,當窄帶ip撥號業務分流需求較大時,可考慮採用網關方式。
  6. The normal user must go through the access network and backbone to access the internet via icp there are always high - rate and broadband lines connected to the backbone, the backbone of telecom can provide wide enough bandwidth for all the data transmission as more and more optic fiber with wdm and dwdm technologies have been paved. but " the last mile " from user ' s home to central office is still narrow - band and analog, which becomes bottom - neck of the communication subnet preventing it from being widen

    一般用戶使用internet時要經過接入網,電信主幹網,最後達到icp ( internetcontentprovider :因特網內容提供商) 。其中icp一般有著高速寬帶的線路與主幹網相連,而主幹網由於波分復用或密集波分復用的光纖技術的大量使用,使得其可提供足夠的帶寬使用,但是,接入網? ?從用戶家庭到電信網的局端的這「最後一公里」 ,仍然是窄帶的、模擬的,這「最後一公里」就是電信網寬帶化的瓶頸。
  7. Thus the evolution from narrow - band to broadband network is irreversible

    從窄帶網路到寬帶網路的演進是不可逆轉的。
