"With the introduction of the digital data system (DDS), some subscribers that transmit digital signals have been incorporated into the network."

随着数字数据系统的引入，有些传输数字信号的用户已经并入该网。

"The digital channel includes the circuit section between an end user and the network, that is to say, the transmission on the end user's loop should be digitalized as well."

数字信道应包括用户到网络的连接线在内，即用户环路的传输也应是数字的。
