  2. Before the 1990s, the digital transmission equipment was based on the technical standards of plesiochronous digital hierarchy ( pdh ). in order to connect the switch to pdh transmission equipment, the switch side needs lots of terminal equipment of the primary rate, i. e., 2048 kbits ( 2m ) switching terminal circuits in compliance with itu - t standards ( e. g. s1240 s dtm trunk module and axe10 s etc module ) and ansi - standard - based 1544 kbits ones

    在90年代初期以前，數字傳輸設備是建立在pdh （ plesiochronousdigitalhierarchy ）技術標準上，為了連接交換機到pdh傳輸設備上，在交換機側需要大量的符合基群速率的終端設備，即符合itu - t標準的2048kbits （ 2m ）交換終端電路（如s1240的dtm中繼模塊， axe10的etc模塊）和符合ansi標準的1544kbits交換終端電路等。
  3. This article uses cpld technology to improve the hardware integration degree so as to ensure the high system reliability ; it applies digital signal process technology to producing and recognizing large volume ditigal voice signals in switch systems ; it replaces the old - used special voice signal process chips, thus lowers the cost, improves the quality ; it uses high quality common pc 104 units to complete the main processor tasks, which greatly improves the signal processing capability in the digital switch systems, and provides a great convinence for future technology upgrade as well ; in system archtecture, we exploit modular design technique on client ports and repeater ports, which gains more reliability and easy maintenance

    本文主要採用了cpld技術提高硬體的集成度以保證系統的高可靠性：用數字信號處理技術完成交換系統中大量的語音信號的產生和識別，代替以前的專用語音信號處理晶元，降低了成本，提高了性能：用高性能的通用pc104單元完成主處理機的工作，大大提高了數字交換系統的信息處理能力，並為今後的技術升級提供了方便：在系統結構上對用戶埠和中繼埠採用模塊化設計，性能可靠，維護方便。
  4. The tests indicate that digital signals can be transmitted 70 kilometers by the optical transceiver in the single - mode optical fiber without any relay, which meet the aim of the study
