2.3.4 – X-Pol RBS Tx and X-Pol RBS Rx
The X-Pol RBS Tx is a transmitter radio that connects to an antenna. The X-Pol RBS Tx receives an IF
channel from each of one or more IBS-TLX cards, upconverts the IF signal to RF, and sends the RF
signal to the transmit antenna.
The X-Pol RBS Rx is a receiver radio that connects to an antenna. The X-Pol RBS Rx receives an RF
signal from one or more NIUs through the connected antenna, downconverts the RF signal to IF, and
sends the IF signal to the IBS-TLX card.
Figure 3 shows the X-Pol RBS Tx and X-Pol RBS Rx connected to antennas.

32/346
104
Issue 01 - April 2001 - Draft 04
3CC12426AAAA TQ BJA 01
Power
The MainStreetXpress 36170 shelf consumes a maximum of 1050 W of power. Each –48 V power
supply used to power an X-Pol RBS Tx or X-Pol RBS Rx radios consumes 50W of power.
Electrical ground access

territorial, regional and municipal regulations for absorbing energy discharge from lightning arresters.
Temperature and environmental control
The air temperature in the equipment room must be maintained in the range of –5 to +55°C (+23
to +131°F). This may require installing an air conditioning system, and a back-up air venting system. Additionally, the equipment room must provide protection from precipitation, seeping water
and humidity.
Cables must enter the equipment room through feed-through, weatherproof rubber cable portals
capable of handling the BS configuration and growth plans.
Fire suppression
The equipment room must be equipped with a chemical fire suppression system that complies
with all international, national, territorial, regional and municipal fire safety codes.
Cable guides
Cable guides and ladders should be used appropriately to route cable both inside and outside the
equipment room.
Controlled access
Only authorized personnel should have access to the equipment room.
2.4.2 – BS installation overview
Note 1 - BS components and cables must be installed and serviced by trained personnel who
are experienced in the local, national and civil electrical and safety regulations of the area
where the equipment is being installed.
Some areas require that only licensed individuals may install and service equipment. Consult
appropriate local authorities prior to installation.
Note 2 - All IF cabling must meet local safety and building code requirements.
Customer-supplied equipment
Customers installing a BS need to supply:
– attenuators,
– IF cable,
– a grounded entry point,
– ground wires and connectors,
– weatherproof cable entry panel(s),
– poles or towers for mounting X-Pol RBS Rxs and X-Pol RBS Txs,
– miscellaneous supplies and connector tools (such as butyl electrical tape, cold-shrink tubing, cable cutter, wire stripper and crimping tool),
3CC12426AAAA TQ BJA 01
Issue 01 - April 2001 - Draft 04
33/346
104
– cable guides and ladders,
– cable hangers and cable grounding kits,
– antenna heaters (to prevent antenna icing).
Grounded entry point
Each BS requires a grounded entry point in order to ground BS components and cables. Refer to local
electrical code requirements when choosing a grounded entry point for the BS.
Lightning protection
BS site lightning protection requires:
– installing lightning arresters on IF and RS-422 cables,
– grounding X-Pol RBS Txs, X-Pol RBS Rxs and mounting poles,
– grounding IF cables,
– lightning rods.
Lightning arresters
The installation of both IF and RS-422 cable lightning arresters is strongly recommended. If lightning arresters are not used, equipment is not covered by the warranty agreement.
Lightning arresters should be installed as close to the rooftop IF cable entry point as possible. Lightning arresters must be grounded according to international, national, territorial, regional and
municipal safety codes.
Lightning rods
Equipment that may be subject to lightning strikes must be protected by a lightning protection system that is installed in accordance with all applicable international, national, territorial and local
regulations and practices.
This may require the installation of lightning rods, a rooftop ground loop, and a main building
ground.
X-Pol RBS Tx and X-Pol RBS Rx
The X-Pol RBS Tx and X-Pol RBS Rx cases, mounting bracket and mounting pole must be grounded to the building power utility ground.
IF cable
IF cables must be grounded at the cable entry point, every 50 m (164 ft) between the cable entry
point and the X-Pol RBS Tx or X-Pol RBS Rx, and at the base of a tower.
Use a standard cable grounding kit available from the recommended cable manufacturer.
IF cable installation
IF cables provide a signal path for data, and power for the X-Pol RBS Tx and X-Pol RBS Rx. IF cables
should be approved by Alcatel, and rated for the particular environment where they are installed (indoor,
outdoor, riser or plenum).
Cable run requirements for the inside and outside of the equipment room vary from site to site. Alcatel
currently recommends only certain cable types, connectors and manufacturers. However, customers
can contact Alcatel to inquire about using alternate cable solutions if the currently approved cables do
not suit a specific application.
Because there are many factors associated with choosing a suitable IF cable, customers are advised by
Alcatel of the manufacturers and part numbers recommended for these cable assemblies.
34/346
104
Issue 01 - April 2001 - Draft 04
3CC12426AAAA TQ BJA 01
Caution - When installing IF cable, use the connectors and connector tools recommended
in Appendix A. Failure to do so could damage the connectors or result in poor signal quality.
Weatherproofing
IF cable connectors and cable entry points must be weatherproofed.
IF cable connectors
Moisture in IF cables causes an increase in VSWR that increases signal loss beyond the specifications of the system. All IF cable connections should be weather-proofed using butyl tape, or
cold-shrink kits available from the cable or connector manufacturer.
RS-422 data cable LEMO connectors
The RS-422 data cable LEMO connector is a waterproof connector when properly assembled. Additional weatherproofing is not required.
X-Pol RBS Tx, X-Pol RBS Rx and antennas
If an X-Pol RBS TxX-Pol RBS Tx or X-Pol RBS Rx is removed from an antenna, care must be
taken to ensure the O-ring that seals the RF channel between the X-Pol RBS Tx/X-Pol RBS Rx
and antenna is correctly installed when the X-Pol RBS Tx/X-Pol RBS Rx is reconnected to an antenna.
Cable entry point
In order to keep moisture from entering the building, cable entry points should be weatherproofed
using a feed-through weatherproof rubber cable portal.
Where a cable runs down a wall to enter a building, a drip-loop or bend in the cable is required to
ensure that rainwater does not follow the cable into the building. The drip-loop or bend causes rain
water to drip from the cable before it reaches the cable entry point.
X-Pol RBS Tx and X-Pol RBS Rx installation
The X-Pol RBS Tx and X-Pol RBS Rx must be connected to antennas before being mounted on towers,
masts, building rooftops or other appropriate fixtures.
BS antennas connect to mounting hardware that is attached to 11.43 cm (4 1/2 in.) outer diameter steel
mounting poles at preselected locations on a rooftop.
Note - The required inner diameter (wall thickness) of a mounting pole must be determined
by professional engineering staff, taking into consideration the torsional and vibrational
forces caused by the wind loading on the pole and on the equipment mounted on the pole,
as well as the distribution of these forces on the supported and unsupported parts of the pole.
Vertical and horizontal spacing between X-Pol RBS Txs and X-Pol RBS Rxs is provided by cell planning
activities, and must be adhered to.
Power for each X-Pol RBS Tx and X-Pol RBS Rx is delivered by the IF cable. No additional power
delivery is required for the radios.

2.5 – Installing BS X-Pol RBS Txs, X-Pol RBS Rxs and antennas
2.5.1 – Overview
This chapter describes how to:
– attach an X-Pol RBS Tx or X-Pol RBS Rx to an antenna,
– attach antenna mounting plates to a pole,

– attach antennas to mounting plates,
– ground the X-Pol RBS Tx and X-Pol RBS Rx,
– adjust antenna downtilt,
– replace a X-Pol RBS Tx, X-Pol RBS Rx or antenna.
Note - X-Pol RBS Txs, X-Pol RBS Rxs and antennas must be installed and serviced by
trained personnel who are experienced in the local, national and civil electrical and safety
regulations of the area where the equipment is being installed.
Some areas require that only licensed individuals may install and service equipment. Consult
appropriate local authorities prior to installation.
BS antennas connect to mounting hardware that is attached to 11.43 cm (4 1/2 in.) outer diameter steel
mounting poles at preselected locations on a rooftop.
Note - The required inner diameter of a mounting pole must be determined by professional
engineering staff, taking into consideration the torsional and vibrational forces caused by the
wind loading on the pole and on the equipment mounted on the pole, as well as the
distribution of these forces on the supported and unsupported parts of the pole.
The location of the mounting poles, the distance between X-Pol RBS Txs and X-Pol RBS Rxs, the height
of the X-Pol RBS Txs and X-Pol RBS Rxs on the mounting poles, and the polarization of the X-Pol RBS
Tx and X-Pol RBS Rx antennas are determined as part of cell planning. The distance required between
X-Pol RBS Tx and X-Pol RBS Rx antennas is either a horizontal or vertical distance, as shown in Figure
8.

2.5.2 – Attaching an X-Pol RBS Tx or X-Pol RBS Rx to an antenna
Each X-Pol RBS Tx and X-Pol RBS Rx must be connected to an antenna in a clean indoor environment,
on a surface that is suitable for electronic assembly, before the antenna is mounted on the BS pole
assembly.

To install an X-Pol RBS Tx or X-Pol RBS Rx on an antenna that is already attached to a mounting plate,
the antenna must be removed from the mounting plate without disturbing the antenna downtilt. See
procedure 6-6 for information on removing an antenna from a mounting bracket.
Note 1 - Do not remove the shipping caps from the coaxial and RS-442 connectors on the
X-Pol RBS Tx and X-Pol RBS Rx until the BS cables are ready for attachment.
Note 2 - Antenna polarization is specified in cell planning, and cannot be changed without
affecting network performance. Use the appropriate Tx and Rx antenna polarization for XPol RBS Txs and X-Pol RBS Rxs in a given sector, as specified by cell planning activities.
To attach an X-Pol RBS Tx or X-Pol RBS Rx to an antenna
1. Remove the RF wave guide cover from the X-Pol RBS Tx or X-Pol RBS Rx, and remove the RF wave
guide plug from the antenna. Figure 9 shows the location of the cover and the plug.

2. Place the radio on a flat surface, with the wave guide facing up.
3. Place the provided O-ring on the O-ring seal seat around the X-Pol RBS Tx or X-Pol RBS Rx RF
wave guide. Ensure that the O-ring remains in place during the remainder of the procedure.
4. Place the antenna on the radio as shown in Figure 10, ensuring that the captive bolts align with their
threaded standoffs. Tighten each of the three captive Hex bolts to 2.37 Nm (21 in.-lb) torque.
