HDSL的音标

The implementation of the high bit rate digital subscriber line ( HDSL) dynode systems is discussed, the design scheme of practice systems, and practice test data are given, come recommendation for HDSL technique is proposed.

对超级数字用户线路倍增系统的实现进行了讨论，给出了一个实际实现系统的设计方案及其实测数据，对利用高比特率数字用户线（HDSL）技术提出了一些建议。

In HDSL ( High bit-rate DSL) and SDSL ( Symmetric DSL) the data stream is symmetric; that is, the upstream and downstream rates are the same.

和「对称数位用户回路」（SDSL）的资料流是对称的，也就是说上行和下行的速率相同。

With the development of the broadband integrated service access network, HDSL and ADSL techniques could not satisfy the demand of broadband service due to the limitation of the properties of paired cable, so these two techniques are only transitional.

在宽带综合业务接入网中，HDSL和ADSL技术受到双绞线性能的限制，不能满足高质量的服务要求，只是一种过渡性的技术。
