HDSL技术原理及其维护注意事项

Principle of HDSL Technology and Maintenance Guideline

文章从理论层面简要介绍了高比特率数字用户线(HDSL)接入技术的基本原理,并对HDSL的线路编码、回波抵消和自适应均衡3项关键技术作了进一步阐述和横向比较。同时,从应用层面指出电路开放和系统维护中经常产生的一些问题的解决方法,并列举出相关注意事项,最后对今后的维护工作提出了一些建设性的建议。

This thesis introduces the basic principle of HDSL access technology. It focuses on HDSL line coding / decoding, echo cancellation, auto adapted load balancing and the differences among them. At the same time, during circuit establishment and system maintenance, we often have some problems. This thesis lists the solutions and some tips are given. Some suggestions for maintenance in the future are also given.
