Generally, multiple connection paths are provided between machine rooms and wire racks on different floors, which can also be used for large-area connection of single-storey buildings.

Equipment room subsystem

The machine room is a place where inbound equipment is set at the corresponding position of each building for network management and on duty management personnel. The machine room subsystem consists of building inbound equipment, telephone, data, computer and other host equipment and safety wiring equipment of generic cabling system.

Building complex subsystem
The complex subsystem extends the cables of one building to the communication equipment and facilities of other buildings in the complex. It includes copper wire, optical fiber and protection equipment to prevent surge voltage of cables from other buildings from entering the building.
