Horizontal Subsystems:
This section consists of the following:
• Cables, from the patch panel to the work area
• Telecommunication outlets
• Cable terminations
• Cross connections, if required
This subsystem represents the origination of network cables from the appropriate closets and proceed to the work are, ending up at the telecom outlets.
Backbone Subsystems:
These systems are needed in order to link the entrances, equipment rooms, telecommunication closets, cross-connecting cables, mechanical terminations and patch cables.
Telecommunication Rooms:
Also referred to as TR or the Closet is place of the backbone connections, which is comprised of networking cable.
Other apparatus like the switches, routers, repeaters, and LAN hubs are fixed here.
Equipment Room:
The name says it all here and it is the place that stores the communication equipment as well as the special data. It is a regulated environment as fragile components are kept here.
Entrance Facility:
External service providers make use of this space as it is where the fix their cables with the cabling facility you have installed.
So having a structured cabling system is even easier than most people thought and because the benefits are enormous, you should really consider having one installed.
