Preface
About this Manual
ZXDSL 9210 (V3.1) Broadband Universal Access Equipment (called ZXDSL 9210 for
short) is a high-speed digital subscriber transmission line developed by ZTE based on
VDSL and ADSL. The system implements bi-directional transmission of high-speed
digital signals over a common pair of twisted telephone wires, which greatly improves
the line utilization of a PSTN.
In order for you to better understand the equipment and grasp the methods of
engineering installation, operations, and routine maintenance, we have compiled a
whole suite of user documents, including
