2.2.2 Cleanliness

Dust is very harmful to the safe operation of the gateway. Dust that is adsorbed by static electricity acts as
insulator, which not only affects the service life of the gateway but also leads to communication failure.
Therefore, the room for the gateway must be kept clean.
To ensure adequate ventilation to keep the gateway from overheating, there should be adequate clearance
for the air intake and the air exhaust vents. Keep at least 6 cm clearance at the left and right side of the
chassis where the air intake is and at least 15 cm clearance at the rear of the chassis where the exhaust
vents located.
The rack for TGWXE1 should have a good ventilation system.

2.2.3 Power Supplier

Check the power supply system against the electrical specification of the gateway.

2.2.4 Grounding

To maintain good voice quality, proper grounding of the AC supply is critical to minimize the noise from
the AC interference. Therefore, the following conditions must be ensured:
The AC power outlet has a protection ground contact.

The ground contact of AC supplier must be grounded properly.

Avoid sharing the multi-outlet power strip with other devices that may generate electrical interference.

TGWXE1 is chassis based with ground tab.
In a site that can provide ground for the chassis, the ground tab at the rear panel of chassis for TGWXE1
must be properly grounded.

2.2.5 Electromagnetic Environment

Any possible interference source, wherever it is from, impacts the gateway negatively. To resist the
interference, make sure that:
Keeping the gateway far from radio transimitting station, radar station, and high-frequency devices.

Use electromagnetic shielding when necessary.
The gateway is capable for secondary lighten protection on wires and cables that connected to outside

buildings.The site must provide the primary lighten protection.
The power supply system should be used independently as much as possible and effective measures of

preventing electric grid from interference should be adopted.
Ensure a good power grounding effect of equipment or add a lightning protector.

2.2.6 Other Facilities

Rack/Workbench

TGWXE1 is designed to be installed in a standard 19-inch rack, which should provide adequate
air-flow to cool down the gateway, and should be firm enough to support the weight of the gateway. It
is also recommended the rack is earth grounded properly.
PSTN Line

If the gateway is equipped with T1/E1 interface, be sure to subscribe PSTN lines from local telephone
company and activate the lines prior to the installation.
IP Network
