  5. At the beginning, this paper has some brief dissertation on the basic principle of the dsl and the multimedia data compression, the key technique of sdsl, the transport protocols, and the data transfer system structure based on the twisted - pair. then it gives an analysis of the point - to - point data link protocol ( ppp ) and the real - time transmission protocol in detail, which provide the side - to - side transmission service for audio frequency and video frequency data, and so on based on the these, we developed a multimedia sdsl modem system used to transfer data and phonetic

    本文首先對dsl系統和多媒體數據壓縮技術的基本原理、 sdsl的關鍵技術、傳輸協議以及基於雙絞線的數據傳輸系統的結構進行了簡要的論述，並詳細分析了點到點的數據鏈路協議（ ppp協議）以及實時傳輸協議，其為音頻、視頻等實時數據提供端到端的傳送服務。可以向接收端傳送恢復實時信號必需的定時和順序信息，並向收發雙方和網路運營者提供qos監測手段。
  6. Rate symmetric xdsl includes idsl, hdsl, sdsl ( single line dsl ), hdsl2 and so on

    Xdsl技術按上行和下行的速率是否相同可分為速率對稱型和速率非對稱型兩種。
