Placement of transmitting equipment
To prevent exposure to non-ionizing radiation, the X-Pol RT should always be mounted at a minimum of
3 m (10 ft) above ground level or roof-top level. An X-Pol RT that is mounted on a wall should be mounted
at least 3 m (10 ft) away from any point of exposure such as windows, balconies or doors.
X-Pol RT service and repair safety precautions
Only authorized personnel should service X-Pol RT units.
Danger - Never touch the X-Pol RT antennas while they are in operation. Do not stand in
front of X-Pol RT antennas, and never pass closer than 1 m (3 ft) in front of an operating or
X-Pol RT.
Power to X-Pol RTs must be disconnected prior to installation or servicing.
Service and repair preparation activities should be made as close as possible to the base of
an elevated X-Pol RT, as the risk of exposure to non-ionizing radiation increases as you
move further from the base toward the area that is serviced by the transmitter.
Equipment interconnection points
All card faceplate connectors are SELV.
Connect SELV circuits on this equipment only to other circuits that comply with the requirements of SELV
circuits as defined in EN60950.
Restriction of unauthorized access
Only authorized personnel should have access to the equipment. Install the equipment in a restrictedaccess location or similar environment, and post appropriate warning signs to indicate safety concerns.
Failure to prevent unauthorized user access will invalidate any approvals given to this equipment.
Regulatory symbols
The following sections show examples of regulatory approval symbols generally used. They may be
used on product markings such as approval labels. These symbols are described in IEC417.

United States Federal Communications Commission regulations
This equipment has been approved to the Federal Communications Commission Part 68 Rules as not
being harmful to the telephone network when connected directly to telephone lines. Customers must,
upon request from the telephone company, provide the following information:
– FCC Registration Numbers
– USOC: RJ48C
– FIC: 04DU9-BN/DN/1KN/1SN
– SOC: 6.0Y
The FCC identification number can be found on the product label located on the product chassis.
The REN determines the number of devices that users can connect to their telephone line and still have
the assurance that these devices will ring properly when their number is called. In most, but not all areas,
the sum of the RENs for all devices should not exceed five (5.0). To determine the maximum number of
devices users can connect to their line, as specified by the REN, users must contact the local telephone
company and request the information on the maximum REN for their calling area.
If the user equipment causes harm to the telephone network, the telephone company may temporarily
discontinue service to the line. If possible and practical, the company will notify the user in advance. If
not, the company will notify the user as soon as possible. Included in the notification, the users will be

The single NT configuration is composed of a single X-Pol RT and a single NT. The dual NT configuration
is composed of a single X-Pol RT and two NTs linked to the X-Pol RT via a splitter module. The single
NT configuration pre-wired for and additional NT is identical to the Dual NT configuration, except that the
second NT and associated cable is replaced by a 75 ohm termination load. This configuration is
recommended wherever a second NT may be required in the future, as it allows the installation of the
additional NT without removing the first NT from service.

3.1 – Equipment delivery
When you receive the equipment in its packaging:
– Check the condition of the packaging.
– If damaged, notify ALCATEL without delay.
3.1.1 – Unpacking
Considerations
You are recommended to:
– unpack the equipment according to the instructions on the packaging, and to the instructions given
below.
– take an inventory and identify any missing items. If the delivery does not match the delivery advice
note, notify ALCATEL within 48 hours of receipt of the equipment.
3.2 – Installing an X-Pol RT
There are two types of X-Pol RTs: side-mount and rear-mount. Both X-Pol RTs have the same part
number, and are shipped according to availability.
Note 1: X-Pol RTs must be installed and serviced by trained personnel who are experienced
in the local, national, international 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: If more than one X-Pol RT is installed at the same customer site, the X-Pol RTs
must be installed at least 1 m (3.28 ft) apart (horizontal or vertical), to avoid blocking line-ofsight access to the BS.
Side-mount and rear-mount X-Pol RTs use the same X-Pol RT mounting bracket, shown in Figure 5 –
X-Pol RT mounting bracket. As indicated in the figure, the rear-mount and side-mount X-Pol RTs mount
to the bracket in two separate locations.

3.3 – To install the X-Pol RT on a pole
For each X-Pol RT:
1. Rotate the X-Pol RT until the polarization arrow on the back of the X-Pol RT radome indicates the
correct polarization, and position the X-Pol RT against the appropriate bracket mounting holes.
The polarization arrow must point sideways for horizontal Tx polarization, and up or down for vertical
Tx polarization.
Always align the X-Pol RT such that a drain hole is at the bottom of the antenna.
2. Attach the X-Pol RT to the mounting bracket using the four supplied bolts, lock washers and flat
washers. Tighten each bolt to 8.8 Nm (6 ft-lb) torque.
Figure 8 – Rear-mount X-Pol RT bolts shows the bolt locations for the rear-mount X-Pol RT, and
Figure 9 – Side-mount X-Pol RT bolts shows the bolt locations for the side-mount X-Pol RT.
Note: The side-mount X-Pol RT requires two flat washers on each bolt that attaches it to
the mounting bracket, in addition to the lock washer. The back-mount X-Pol RT requires
only a single lock washer and a single flat washer on each bolt.

3.4 – To ground the X-Pol RT
The following parts and supplies are required:
– an adequate length of ground conductor
– an M6 ring lug
– a 1.0 thread pitch, 10 mm M6 bolt
– dielectric paste
1. Measure a length of ground conductor sufficient to run from the X-Pol RBS Tx or X-Pol RBS Rx to
the nearest suitable ground point. The required diameter, metal type and physical type of the ground
conductor may vary according to local regulations. Consult local electrical authorities for information.
2. Connect an uninsulated M6 ring lug connector securely to one end of the ground conductor using a
suitable mechanical connection method.
3. Apply an appropriately rated dielectric paste liberally to both sides of the ring lug.
4. Connect the ring lug to the X-Pol RT case with the M6 X-Pol RT ground bolt, located on the side
(side-mount X-Pol RT) or back (rear-mount X-Pol RT) of the X-Pol RT case. Tighten the bolt to
10.8 Nm ± 2.7 Nm (8 ft-lb ± 2 ft-lb) of torque.
5. Connect the remaining end of the ground conductor to a suitable lightning discharge ground, using
a mechanical connection method that is approved by local electrical authorities.
3.5 – Installation of the Terminal Station X-Pol RT unit with a non
integrated antenna
3.6 – Installation of the X-Pol RT/NT link
Procedures
– The electrical connection between the X-Pol RT unit and the NT unit of the Terminal Station is
made using a type FILOTEX or 5916 75 ohm coaxial cable equipped with "F" connectors on each
end.
– If the X-Pol RT unit is connected to two NTs, use one splitter.
– The length of the cable used must be recorded. Refer to the numbers printed on the cable at one
meter intervals to determine the length of cable installed (subtract the number printed on one end
of the cable from the number printed on the other end of the cable).
– Secure the coaxial cable every meter with a cable tie. Use collars fitted to the support used for the
path.

Steps
1. Install the 75 ohm connector between the X-Pol RT unit and the NT unit.
Note: In the event of the use of splitters, use the number of cables required by the configuration.
Note: Make a drip loop where the cable enters the building, respecting the cable's bending radius
(100 mm minimum), in order to prevent water infiltration.
AVOID LONG CABLE RUNS PARALLEL TO CABLES THAT COULD CAUSE
INTERFERENCE (E.G. AC POWER OR GSM/DCS BASE STATION CABLES)
2. Record the length of the cable installed in the 7390 X-Pol RT cabling sheet. This information will be
entered into the database when the equipment is commissioned using the configuration software.
Note: The accuracy required by the configuration software is ± 1.5 m.
3. At the X-Pol RT, install a type "F" 75 ohm coaxial connector (designed for outdoor use) on the cable.
Refer to the manufacturer’s Assembly manual and use the specific tools as recommended for
installing the connector. One of the main causes of installation problems is the faulty installation of
connectors.
ALWAYS USE A "F" CONNECTOR WITH A CENTER PIN NOT EXCEEDING 0.042 INCH.
DIAMETER ANY OTHER CONNECTOR IS USED, THE X-Pol RT COULD BE DAMAGED
IMPORTANT NOTE: NEVER HANDLE THE X-Pol RT UNIT BY ITS ANTENNA. ALWAYS

4. Attach the cable to the X-Pol RT unit using a cable tie.
IF THE COAXIAL CABLE IS INSTALLED IN SUCH A WAY THAT THE CABLE "F"
CONNECTOR IS UNDER EXCESSIVE TENSION, ANTENNA MISALIGMENT OR
CABLE DAMAGE AT THE CONNECTOR CAN OCCUR. HOWEVER, AN
EXCESSIVELY SLACK CABLE CAN CAUSE THE SAME PROBLEMS UNDER THE
EFFECT TO THE WIND. ALWAYS INSTALL THE CABLE IN SUCH A WAY THAT
THE CONNECTOR IS NOT UNDER EXCESSIVE TENSION, AND THAT THE CABLE
CANNOT MOVE OR VIBRATE DUE TO WIND FORCES.
Note: Do no overtighten the cable tie on the cable; this could cause deformation of the dielectric and
subsequent loss of performance.
5. Run the cable to the NT unit and equip it with a type "F" 75 ohm coaxial connector, supplied with the
equipment.
3.7 – Installation of the Terminal Station 7390NT (Indoor Unit)
A SPACE OF 1U (in the event of rack mounting) OR APPROXIMATELY 50 mm
MUST BE LEFT FREE ABOVE THE TERMINAL STATION NT
NEVER PLACE DOCUMENTATION OR ANY OTHER OBJECTS ABOVE THE NT
UNIT ON THE VENTILATION HOLES. THIS MAY CAUSE DAMAGE DUE TO
OVERHEATING
Considerations
– The NT units are designed for indoor installation only.
– The NT should be positioned in accordance with the needs of the user and the technical constraints (e.g., minimum distances to be respected, topology of the connections, accessibility of the
X-Pol RT/NT link, power supply).
– Always place the NT in a dry, dust-free environment, away from any major source of heat
(-5°C < T < +55°C).

– Always place the NCAxxx NT unit near a rated power source: 85 – 264 VAC , 47 – 63 Hz with
ground connection.
Note: Use grounded power connections only. Avoid the use of extension cables.
– The NT to sector connection must be done last, during commissioning (see Chapter 4 – Commissioning the 7390 Terminal Station ), TS installation, included all other connections, being completed.
– Do not install the NT too close to the ground (keep at a distance from dust and floor cleaning products).
– Do not install on premises containing corrosive materials.

3.7.3 – Earthing the NT units
Considerations
– NT casing must be connected to the main earth with a cable 16 mm2 minimal cross-section whose
length must not exceed 2.40 m. The grounding terminal is on the right of the NT unit (connections
side) and is in the form of a tapped hole (see Figure 15 – Earthing the (NCAxxx) NT unit).
– The earth connection should be made as directly as possible between the unit and the general
earthing system of the side (bar, rod, plate, etc.).
– The NCAxxx NT units are grounded through the 85 – 264Va main connector; for the NGAxxx
units, only one earthing point is necessary, after the earthing of all the NT units.
Steps
1. Crimp a lug (ref.: 16-6 CT) on to the earthing cable (16 mm2 cross-section).
2. Screw the cable lug into the terminal designed for this purpose. Use an M6 screw.

4.1 – Commissioning the X-Pol RT
4.1.1 – X-Pol RT adjustment
4.1.1.1 – Overview
This chapter describes how to align an X-Pol RT by adjusting the azimuth, elevation and vertical angle
of an X-Pol RT. The procedure requires a minimum distance of 100 m (328 ft) between the BS and the
X-Pol RT.
The procedure also requires clear weather conditions and a clear line-of-sight between the BS and the
X-Pol RT. There must not be any obstacles in the clear line-of-sight within the following distances:
– within 4 m (13 ft) for a TS site up to 6 km (3.8 mi) away,
– within 7 m (23 ft) for a TS site between 6 and 10 km (3.8 to 6.2 mi) away.
Note: Alcatel Broadband Wireless equipment should only be installed by qualified individuals
who are trained and certified for the type of installation task assigned to them.
Lists the equipment needed to align the X-Pol RT.

– Rx polarization of the TS antenna,
– desired power level of the downstream signal at the NT F connector (labeled IF In/Out and 35 VDC
Out) (see § 4.2 – Commissioning the NT - Table: Malfunctions to the installation),
– Additionally, the insertion loss value of the test equipment (such as cables, couplers and adapters)
must be measured and recorded for this procedure.
4.1.1.2 – Aligning the X-Pol RT
An X-Pol RT must be aligned with respect to the BS X-Pol RBS Tx and X-Pol RBS RX antennas in order
to receive a reliable signal. Figure 17 – X-Pol RT adjustment bolts shows the bolts used to adjust the
azimuth, elevation and vertical angle of an X-Pol RT in relation to the BS.
To align the X-Pol RT to the BS signal, adjust the X-Pol RT mounting hardware to find a position that
provides the desired signal power level. Acceptable power levels are based on RF planning and analysis
that should be done before an X-Pol RT is installed. Typical signal strengths for various cell radii are
given in Table: Malfunctions to the installation.

9. If antenna misalignment is not required as per «8» above, connect the test equipment as shown in
Figure 19 – Antenna misalignment with E-RIT tool (with Enhanced RIT tool) while inserting the
appropriate IGAU type value as recorded in «5» and «6» above. If antenna misalignment is required,
proceed directly to «19».
10. Ensure that the base station is transmitting a signal in the desired sector.
11. Adjust the bolts identified in Figure 15 until the X-Pol RT mounting hardware is sufficiently snug to
hold the unit on the mast, but is loose enough to allow easy rotation of the unit by hand.
12. Switch the NT on.
13. Roughly align the X-Pol RT based on the Radio Network plan.
14. Using the Enhanced RIT tool, fine align the X-Pol RT antenna to maximum field strength and record
the Enhanced RIT tool level and LED status.
15. Determine the calculated maximum received signal level (RSL) using the signal level calculator. In
comparing the measured RSL to the calculated RSL, both values should be roughly the same.
16. Tighten the pole elevation and azimuth bolts to 4.07 Nm (36 in-lb) torque, and the vertical angle bolts
to 10.85 Nm (8 ft-lb) torque.
17. Verify the level measurement using the Enhanced RIT tool to ensure that the X-Pol RT is still aligned
to provide the maximum level. If this level has changed, repeat the maximum alignment procedure.
18. Switch the NT off, disconnect the test equipment and reconnect the IF cable to the NT. Switch the
NT on.
19. If antenna misalignment is possibly required as per «8» above, connect the test equipment as shown
in figure 16 (with spectrum analyzer) while inserting the appropriate IGAU type and value as
recorded in «5» and «6» above.
20. Ensure that the base station is transmitting a signal in the desired sector.
21. Adjust the bolts identified in figure 15 until the X-Pol RT mounting hardware is sufficiently snug to
hold the unit on the mast, but is loose enough to allow easy rotation of the unit by hand.
22. Switch the NT on.
23. Roughly align the TS based on the Radio Network plan.
24. Determine the calculated maximum received signal level (RSL) using the signal level calculator.
25. Determine whether the desired sector configuration is a vertical X-Pol RBS Tx/X-Pol RBS Rx
configuration or a horizontal1 X-Pol RBS Tx/X-Pol RBS Rx configuration.
26. If horizontal, proceed to «32».

3CC12425AAAA TQ BJA 01
27. If vertical, fine align the X-Pol RT antenna to maximum field strength using the spectrum analyzer
and record the level. If this recorded level is already 15 dB below the calculated RSL, natural
misalignment due to the elevation relationship between the BS and TS has occurred and no further
misalignment is necessary. Proceed to «29».
28. If the measured RSL is not 15 dB below the calculated RSL, misalign the X-Pol RT antenna upwards
in the vertical plane until the RSL is 15 dB below the calculated RSL and record the value.
29. Tighten the pole elevation and azimuth bolts to 4.1 Nm (36 in-lb) torque, and the vertical angle bolts
to 10.85 Nm (8 ft-lb) torque.
30. Verify the level measurement using the spectrum analyzer to ensure that the X-Pol RT is still aligned
to the desired level in «28». If this level has changed, repeat «27-29».
31. Switch the NT off, disconnect the test equipment and reconnect the IF cable to the NT. Switch the
NT on.
32. In the case where the desired sector’s X-Pol RBS Tx/X-Pol RBS Rx pair is horizontally separated by
∼ 10 meters worst case, in order for an equivalent amount of CPE antenna gain to be seen by both
the X-Pol RBS Tx and the X-Pol RBS Rx, the CPE should be aligned to the mid point between the
X-Pol RBS Tx and X-Pol RBS Rx. This task can be performed visually within a few hundred meters
where the worst case at 100 m would yield ∼ 16 dB of CPE misalignment to both the X-Pol RBS Tx
and X-Pol RBS Rx respectively. In this case, no elevation misalignment is necessary. As we
approach the AMTR (distance depends on rain region), visual alignment to the mid-point of the XPol RBS Tx and X-Pol RBS Rx becomes more difficult but is not as critical whereby if the CPE were
aligned to the X-Pol RBS Tx instead of the mid-point, the X-Pol RBS Tx would only have ∼ 1 dB
stronger relative antenna impact to the X-Pol RBS Rx, which is acceptable.
33. Record this azimuthal mid-point RSL. If this recorded level is already 15 dB below the calculated
RSL, natural misalignment due to the mid-point TS antenna pattern roll-off and/or the elevation
relationship between the BS and TS has occurred and no further misalignment is necessary.
Proceed to «35».
34. If the measured RSL is not 15 dB below the calculated RSL, misalign the X-Pol RT antenna upwards
in the vertical plane until the RSL is 15 dB below the calculated RSL and record the value.
35. Tighten the pole elevation and azimuth bolts to 4.1 Nm (36 in-lb) torque, and the vertical angle bolts
to 10.85 Nm (8 ft-lb) torque.
36. Verify the level measurement using the spectrum analyzer to ensure that the X-Pol RT is still aligned
to the desired level in «34». If this level has changed, repeat «33-35».
37. Switch the NT off, disconnect the test equipment and reconnect the IF cable to the NT. Switch the
NT on.
4.2 – Commissioning the NT
Note: To carry out the following phases of the Terminal Station commissioning, the link Base Station
must be operational and its antenna correctly orientated.
Considerations
– Before commissioning the NT unit, complete the X-Pol RT unit adjustment procedures.
– No adjustment is required for commissioning the NT.
– To check the voltage at the mains connector terminals, use a measuring instrument (voltmeter).
1.
Please note that Alcatel recommends the use of a vertical X-Pol RBS Tx/X-Pol RBS Rx configuration wherever possible.

– For the mains connection, use only the connection cable supplied with the equipment.
– Never use an extension cable for connecting the NT unit to the power source.
Stages (Figure 21 – The NT unit (85 – 264 V 47 – 63 Hz) a )
1. Connect the X-Pol RT/NT connection cable.
2. To ground the NT unit in this way, carry out the procedures described in Chapter 3 – Installation of
the X-Pol RT’s A7390 Terminal Station. Use the lug and screw hardware supplied with the
equipment, ref. 7.
3. Check that the mains socket to which the NT is to be connected supplies voltage compliant with the
equipment characteristics and that it is fitted with an earth.
4. (ref. 5)
•
For NCAxxx: connect the NT connection cable to the NT connector and then to the mains.
•
For NGAxxx: connect the 48V cable to the HE15-3 connector, then to the 48V arrival.
5. Power-up the NT unit using the On/Off switch (ref. 6); the green "Power on" LED (ref. 3) lights up.
The red "Alarm" LED (ref. 4) lights up (searching for the carrier frequency) then flashes at different
rates according to the current phase:
•
slow flashing: automatic scanning over the frequencies,
•
fast flashing: frame recovery (authentication by the serial number) once the frequency is
found.
Malfunctions to the installation:
The A7390 is a reliable and easy-to-install system. By following the procedures described in the
documentation, no problems should occur. However, if these procedures have been poorly applied, here

4.4 – Initiating services
Once X-Pol RT and NT are installed and in operational status, service initiation requires a further step:
the Base Station operator must activate the cross-connections (see User Manual 3CC12426 Axxx Base
Station § Client Services and § 6.2 – Implementation of client services of the present document).
4.5 – Filling in the installation sheet
The installation sheet (Appendix 1 – 7390 TS installation sheet) is initially issued by Radio Planning. It
contains all the data needed by the installer for successful programming of the X-Pol RT.
The installer must complete this sheet by supplying the requested information, in particular the serial
numbers of the installed equipment, then submit it to the supervisor. The information in the sheet
ensures the traceability of the customer installation equipment, to facilitate subsequent interventions.
The sheet should be signed by the client and the installer. It allows with the customer, the effective
commissionings to be validated.
The sheet consists of three parts:
– 7390 X-Pol RT installation sheet,
– 7390 NT installation sheet

6 – Changes of configuration
During the life-cycle of an Alcatel A7390 LMDS network, both physical and software configuration
changes will likely occur for reasons of both network growth and maintenance.
The supervisor must be informed of any configuration changes
These changes may involve either changes of configuration using the 7390LT software, or changes to
the physical equipment (X-Pol RT or NT).
The possible changes using the 7390LT software only are:
– declaration/removal/reset of an NT terminal (cf. § 6.1 – Declaration, deletion, reset of an NT),
– implementation of client services (cf. § 6.2 – Implementation of client services).
The possible changes with physical intervention are:
– addition/removal of an NT unit (cf. § 6.1 – Declaration, deletion, reset of an NT),
– changing an NT unit (cf. § 5.4 – Changing a faulty NT unit),
– changing an X-Pol RT unit (cf. § 6.3 – Changing an X-Pol RT),
– addition of an NT to a cluster (cf. § 6.4 – Adding an additional NT to a TS site),
– affectation of an NT unit to another BS (cf. § 6.5 – To asign an NT to an alternate BS).
6.1 – Declaration, deletion, reset of an NT
To add a new NT:
– update the "Installation information" sheet required for station installation (refer to Appendix 1 –
7390 TS installation sheet),
– carry out installation (refer to Chapter 3 – Installation of the X-Pol RT’s A7390 Terminal Station)
and commissioning (refer to Chapter 4 – Commissioning the 7390 Terminal Station) of the NT,
– to declare the new NT terminal, execute the commands indicated in section Declaring a new NT
of the Base Station User Manual (3CC 12426 Axxx).
To delete a NT from the network:
– update the "Installation information" sheet required for station installation (refer to Appendix 1 –
7390 TS installation sheet),
– execute the commands indicated in section NT deletion of the Base Station User Manual (3CC
12426 Axxx),
– turn off power to unit using ON/OFF switch (reference 6 of Figure 21 – The NT unit (85 – 264 V
47 – 63 Hz) a ).
To reset a NT :
– execute the commands indicated in section NT reset of the Base Station User Manual (3CC
12426 Axxx)

6.4 – Adding an additional NT to a TS site
When a Terminal Station is installed, and an additional NT is expected to be required in the future, the
cabling on the site can be pre-wired with a splitter. One port of the splitter is connected to an NT, and a
75 ohm termination load is connected to the other port. By removing the termination load and connecting
an additional NT in its place, an additional NT can be added without interrupting traffic on the original NT.
If a Terminal Station is not pre-wired to accept an additional NT, cables must be disconnected, cable
lengths adjusted, and a splitter added. The original NT is unable to pass traffic during the installation of
an additional NT.
6.4.1 – Case of a pre-wired installation
In the case of a pre-wired installation, the cables are already pulled, the distribution frames and splitter
are already in place and there is a 75 ohm termination load on the spare splitter port.
To add an NT to a pre-wired TS site (see § 2.5 – Examples of configuration of the Terminal Station
(7390TS)):
– remove the 75 ohm termination load,
– connect the NT in place of the 75 ohm termination load,
– follow the procedure for adding an NT described in § 6.1 – Declaration, deletion, reset of an NT.
Note: There is no service interruption and, furthermore, it is not necessary to reconfigure the radio
parameters of the X-Pol RT.
6.4.2 – Case of a non-pre-wired installation
In a non-pre-wired installation,
– turn off the power to the existing NT
– install and connect the splitter and distribution frames, and adjust the cable lengths if required.
– follow the procedure for adding an NT described in § 6.1 – Declaration, deletion, reset of an NT,
– reconfigure the X-Pol RT radio parameters.
Note: You are recommended, with a view to possible future Multi-NT use, to wire as for Multi-NT on
first installation. This means that it will not be necessary to reset the X-Pol RT, so avoiding the
interruption of services.
6.5 – To asign an NT to an alternate BS
To assign a Terminal Station to on alternate Base Station:
– delete the NT in the BS with the 7390LT software (cf. § 6.1 – Declaration, deletion, reset of an NT),
– declare the NT in the new BS with the 7390LT software,
– turn off the power to the NT unit,
– allign the Terminal Station X-Pol RT to the new Base Station. Refer to Chapter 3 – Installation of
the X-Pol RT’s A7390 Terminal Station for information.

5 – Operation and maintenance
5.1 – 7390 system supervision
The system operator receives the alarms sent by the network equipment. With the aid of the the 7390LT
software applications, the operator can view and analyze the alarms and trigger the appropriate
operations (see specific procedures below).
On detection of a fault, the operator analyzes alarms and starts the suitable maintenance actions.
5.2 – Preventive maintenance
This maintenance is carried out, either during a corrective maintenance inspection, or during a periodic
inspection, on all station equipment. It consists in inspecting the units and their interconnections
(connectors, cables, sockets, etc.) and ensuring that the environment of the Indoor Units (NTs and RTs)
complies with installation requirements (see § 3 – Installation of the X-Pol RT’s A7390 Terminal Station).
It is essential to check connectors and splitters state with earthing.
In case of doubt, the suspect parts should be checked, taking all precautions to avoid interrupting link
data transmission.
5.3 – Corrective maintenance
DO NOT OPEN THE EQUIPMENT UNDER ANY CIRCUMSTANCE
Corrective maintenance is carried out with the use of the programs of the 7390LT software.
To use the alarms refer to section "Alarms" of the Base Station User Manual 3CC 12426 Axxx.
5.4 – Changing a faulty NT unit
Make sure that the network manager has deleted the NT to be replaced beforehand and declared the
