  5. 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。
  6. All these changes took place after the first spc exchange was put into service in the capital in 1984, enabling the use of pcm circuits for local trunks

    這是從1984年北京開通第一個程式控制交換局，首次在市內中繼使用pcm數字電路之後巨大的變化。
  7. 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。
  8. Based on the results, beijing telecom has forwarded its suggestions to relevant vendors, who in turn have made a number of improvements in their later product versions. with the stm - 1 link as the inter - office trunk, the number of ddfs will be markedly reduced, thus saving floor space in the pit and wiping off distribution - related failures. besides, the number of outgoing trunks will be brought down, thus demanding less maintenance staff and improving the maintenance efficiency

    交換機利用stm - 1鏈路作為局間中繼線路，可以減少數字配線架ddf的數量與規模，從而大大節省局房佔用面積，解決局房面積緊張的問題；還可大大減少配線數量，去除因配線引起的故障；另外，交換機利用stm - 1鏈路作為局間中繼線路，可以減少出局中繼線路數量，從而可以減少維護人員對中繼線路進行維護的工作量，提高維護效率。
