一种实现上行数据传输的方法和终端
摘要：
本发明公开了一种实现数据传输的方法、一种同轴网络终端(CNU)以及一种同轴线路终端(CLT)。在本发明方法中，CNU确定数据在CNU与CLT之间的传输路径损耗；CNU根据所确定的传输路径损耗来确定出上行数据发送电平幅度，并且，CNU利用所确定的上行数据发送电平幅度来发送上行数据。在本发明中，CNU内部包括：路径损耗确定单元、发送电平幅度确定单元以及收发单元。CLT内部包括：下行数据处理单元以及收发单元。本发明从根本上保证了以太网无源同轴网络(EPCN)系统中上行数据传输的安全性，大大提高了业务服务质量。
摘要（英）：

The present invention discloses a method for realizing data transmission, a coaxial network unit (CNU) and a coaxial line terminal (CLT). In the method according to the invention, the CNU confirms the transmission path attrition of the data between the CNU and CLT. The CNU confirms the transmission level extent of the ascending data according to the confirmed transmission path attrition, and furthermore, the CNU transmits the ascending data with the confirmed transmission level extent of the ascending data. According to the invention the inner part of CUN comprises a path attrition confirming unit, a transmission level extent confirming unit and a receiving/transmitting unit. The inner part of CLT comprises a descending data processing unit and a receiving/transmitting unit. The method of the invention guarantees the safety of the ascending data transmission in the Ethernet passive coaxial network (EPCN) system from the root, and the service quality is greatly improved.
