For a site with 4 Bases stations: - 42U*600*600 mm – - Weight (approximatively) : 235 Kg

For a site with 2 Bases stations:

- 42U*600*600 mm - Weight (approximatively) : 190 Kg



• 4 or 2 Base stations, depending of the configuration.

• RX combiner

• Tx combiner The TX combiner is composed of one cavity per base station and one duplexer.

• One GPS splitter

• One main circuit braker for all the cabinet

• One circuit braker per base station.

1.3 CONNEXION

For each radio site, you will have to install several coaxial cables:

• One feeder for the GPS • One feeder for the reception/emission antenna • One feeder for the reception antenna (diversity reception)

You will also have to connect:

• The power supply ( 48 Vdc )

• The external alarms (e.g. for the power station) • The Ethernet link for each Base station.

1.3.1 BASE STATION NETIS 25 D

Front side of the base station (Netis 25D)

1.3.3 INPUT FOR EXTERNAL ALARMS

External alarms : Number Designation Color and description 1 Earth 14 E0 : 15 E1 : 16 E2 : 17 E3 : 18 E4 : 19 E5 : 20 E6 : 21 E7 : e.g. : power alimentation.

1.3.4 COUPLING SYSTEM

For each radio site, two TETRA antennas will be used:

• One antenna for transmission and reception • One antenna for reception (diversity option)

The coupling system is composed of one cavity per base station, a duplexer and a RX combiner. The cavity is nearby the base station, as show on the base station picture. The duplexor is located at the rear of the cabinet. The first TETRA antenna is connected to the duplexor by a N connector.

1.4 POWER SUPPLY

All radio sites will be powered by 48 Vdc. The power consumption:

• Cabinet with 2 BS: 750W • Cabinet with 4 BS: 1250W



2. SWITCH TETRA

For one TETRA switch, equipments will composed of: One 42 U Cabinet : Main specifications for the cabinet:

• Front door and rear door screened with a lock.

• dismountable steel cabinet frame

• 4 rollers.

• earthing set 2.5mm².

• Seize:

- 42U*600*600 mm – - Weight (approximatively) : 180 Kg



2.1 TETRA SWITCH CABINET

Cables access for coaxial cable and power supply will be at the top of the cabinet.
