(In a cabling system, changes in network usage can cause junctions to move, increase and change frequently. Once there is no sign or an inappropriate sign is used, the end user will have to pay higher maintenance costs to solve the management problem of the connection point. The office of building and maintaining the sign system runs through the process of wiring construction, use and maintenance. A good sign system will add a lot to the wiring system; poor quality signs will bring endless pain and trouble.
Five parts of a cabling system need to be identified: cable (telecom medium), channel (trough/duct), space (between equipment), termination hardware (telecom medium termination), and ground)
