What's Construction Requirements

3

Area
The TR should be able to house all the planned equipment.

Indoor height
The indoor height indicates the distance between the floor and the beam or ventilation pipe of the TR. The height cannot be less than 3 meters.

Floor
It is recommended that the TR also have a movable raised floor properly. The horizontal tolerance in each square meter must be less than 2 meters. If a movable raised floor is not available, static electricity conductive floor materials with the volume resistivity of 1.0 x 107 ohms to 1.0 x 1010 ohms should be used instead. The static electricity conductive floor materials or the movable raised floor must be connected to a ground point through a current limiting resistor and a connection line. The resistance of the current limiting resistor should be 1 megohm.

Load-bearing capacity
The load-bearing capacity should be greater than 450 kg/m2.

Doors and windows
The doors and windows must be sealed with dust-proof plastic tapes. It is recommended that windows be constructed with double-layer glass and be sealed properly.

Wall surface
The walls can be pasted with wallpapers or daubed with flat paint. Note that the paint that can be easily pulverized must not be used.

Water pipe
It is recommended that water supply pipes, drainpipes, and storm sewers should not be routed across the TR. Fire hydrants must be installed in a corridor or near a staircase where convenient access is possible.

Internal partition wall
The area where the server is installed should be isolated from the door of the TR by an internal partition wall, because an internal partition wall can prevent dust from entering.

Installation position of air conditioners
Air conditioners should be installed in a proper position where the air does not blow directly at the server.

Other requirements
Measures should be taken to prevent micro-organisms such as fungi and molds and rodents such as rats from entering the TR.

What's Illumination Requirements
The TR should be equipped with the following illumination systems: Active illumination system, which is powered by the mains supply. Backup illumination system, which is powered by the backup power supply (such as the diesel electric generator) in an office. Emergency illumination system, which is powered by storage batteries when the mains supply has been interrupted but the backup power supply has not yet started to supply power.

What's Layout Requirements
The TR mainly houses communication equipment, transmission equipment, and supporting equipment such as power supplies. For ease of maintenance and management, the equipment should be arranged in a compact manner and installed in different rooms depending on the service type. The layout should meet the requirements for easy wiring of communication cables and power cables and for easy maintenance of equipment.

What's Site Selection Requirements
The TR should be At least 5 kilometers away from heavy pollution sources such as smelteries and coal mines. At least 3.7 kilometers away from medium pollution sources such as chemical, rubber, and galvanization industries. At least 2 kilometers away from light pollution sources such as packinghouses and tanyards. Away from industrial and heating boilers. Away from dusty roads or sand fields. If this situation is unavoidable, the doors and windows of the TR should not be facing the pollution sources. Away from livestock farms. If this situation is unavoidable, the TR should be in the upwind direction of livestock farms. Note that an old livestock room or fertilizer warehouse should not be used as the TR. NOTE: If one or more of these requirements cannot be met, ensure that the TR is situated in the upwind direction of the pollution sources. The air vents of the TR should be located far away from the exhaust of city waste pipes, large cesspools, and sewage treatment tanks. The TR should be in the positive pressure state. Otherwise corrosive gases will enter the TR and corrode components and circuit boards. The TR should be at least 3.7 kilometers away from the seaside or salt lakes. If this situation is unavoidable, the TR should be airtight and equipped with air conditioners. In addition, the salt-affected soil cannot be used as construction materials. It is recommended that the TR be on or above the second floor. If this is impossible, the ground for equipment installation in the TR should be at least 600 millimeters above the highest local flood record.
