SDSL

Application of SDSL is experiencing a stage of rapid evolution .

目前SDSL正经历快速发展的应用阶段。

The technique of the Single - line Digital Subscriber Line ( SDSL ) is a new method that realizes high bit rate data transmission on common telephone lines .

单线高比特率数字用户线（SDSL）技术，是用一对普通电话线实现高速数据双向传输的一种新技术。

Site-directed spin labeling ( SDSL ) combined with electron paramagnetic resonance ( EPR ) spectroscopy is a powerful tool for detecting structure of proteins .

位置定向的自旋标记（SDSL）技术结合电子顺磁共振（EPR）波谱技术成为检测蛋白质结构的有力工具。

Also , the paper offers the hardware illustration of SDSL modem , the implemental method of some relevant software , and the voice signal encapsulation transmission issue adopting the real-time transmission protocol .

本文给出了SDSLModem的硬件图和相关的软件实现方法，采用实时传送协议（RTP）解决话音信号的封装传输问题。

Hardware part consists of parameter gathering and processing module , SDSL communication module , serial communication module , intrinsical security power source module , network switch module and embedded intrinsical security computer module .

硬件部分包括数据采集处理模块、SDSL通信模块、串口通信模块、本安电源模块、网络交换模块和嵌入式本安计算机模块。

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。

The DSL 's technology at present has many kinds , among which the SDSL is quick speed , and the upstream is identical as downstream speed , and especially is fit for in up and down volume of flow average person user .

目前的DSL技术有多种，其中的SDSL由于其速度快，而且上行和下行速度相同，特别适合于上行和下行流量差不多的用户。
