| 摘 要： | LDSL是ITU的一个研究课题,其目标是延长DSL传输距离。READSL是LDSL课题发展的第一步,它能使基于G.992.1／G.992.3的ADSL传输距离延长至18kft(约5.5km)。文中分析了延长ADSL传输距离的技术难点以及可行的解决方案,最后介绍了频谱分配技术在READSL中的应用。

| Abstract: | Long-reach DSL (LDSL) is a project of ITU, with the objective to increase the reach of DSL solutions. Range Extended ADSL (READSL) is the first step in the LDSL project. READSL extends the connectivity of G.992. 1/G.992.3 based ADSL up to 18kft. The paper analyzed the difficulty and the feasible technical option in LDSL, and introduced the spectrum allocation in READSL finally. |
