Appendix A Engineering Labels for Cables
Engineering labels are affixed to both ends of the various cables to identify the physical
positions of cables on different devices. Labels on the cables facilitate correct and
orderly connection of cables, and easy maintenance after the installation.
There are two types of engineering labels, specialized for the power cables and signal
cables respectively. The power cables include the AC power cables and DC power
cables (excluding the power cable that connects the distribution box and the cabinet).
The signal cables include external cables of alarm box, Ethernet cables, optical fibers,
trunk cables and subscriber cables (excluding the antenna feeders).
Note:
In case there is special requirement from the user of the equipment on the description
method of the labels, the labels should be printed accordingly. However, this must be
stated in the self-check report.
