单线对高比特率数字用户环路(HDSL2)技术分析

Technical analysis on HDSL2

作为HDSL的下一代产品,单线对高比特数字用户环路(HDSL2)能利用一对双绞线无中继的传输T1/E1数据。本文对HDSL2技术研究面临的一些主要问题,如获得更高的信噪比裕量、频谱兼容性、硬件兼容性和硬件复杂度等进行了分析研究。

Single Pair HDSL(HDSL2), which was also called as the next generation of HDSL, can transmit T1 /E1 without repeaters using only one pair phone line. In this article, we discussed those main problems on HDSL2 research such as noise margin, spectral compatibility, hardware compatibility, and hardware complexity. Some resolving methods of those problems are also proposed.
