1–Foreword
1.1–Structure of the manual
This manual is intended for users with a sound knowledge of how to operate and install point-multipoint
microwave systems and how to use a PC-based craft terminal running the Windows operating
system.
With it, you should quickly be able to operate the equipment. It is not intended to replace the training
services that we can provide for your particular needs.
The manual is divided into seven sections followed by an appendix:
–Foreword
–AMD Radio Performance tool overview
–Installation of the AMD Radio Performance tool
–DBS – PC connection
–Running AMD Radio Performance tool
–Results
–Margin calculation
–Appendix
1.2–Using the manual
With this manual, you should be able to commission and operate the described equipment to a basic
level.
You should always read this manual in conjunction with the attached "Update" document (if provided)
to make you aware of the latest equipment upgrades.
Manual updates
This edition of the manual describes hardware and software releases whose revision indexes are greater
than or equal to those given below:
Hardware revision: 01
In cases where an equipment upgrade affects the content of the manual, the relevant modification should
be inserted in the "Update" document, with the same reference number, but with code type VE (instead
of TQ).
When the number or extent of the changes justifies it, they should be incorporated in the body of the
manual and the manual’s revision index should be incremented. Revision bars will show the differences
from the previous version.

1.3–Safety instructions
1.3.1 –General rules
The following general safety precautions must be observed by the installer and the operator.
ALCATEL assumes no liability for the customer’s failure to comply with these requirements.
–Ground the equipment: for Safety Class 1 equipment, always connect the earth conductor of the
power cable to an appropriate earthing device.
–DO NOT operate the product in an explosive atmosphere or in presence of flammable ga-
ses or fumes.
–For protection against fire: replace the line fuse(s) only with fuse(s) of the same voltage and
current rating and type.
–Dangerous voltages: users must not remove equipment covers or shields. The installation and
maintenance procedures described in this manual are for use by service-trained personnel only.
–Protection against short circuits: the mains equipment should ensure protection against short
circuits according to current domestic standards (residual current differential protection device re-
commended).
–Observe the standards in force for all activities carried out on the roofs.
–For any on-site intervention, observe the precautions against lightning.
–DO NOT operate equipment which may be damaged: its level protection may be altered.
–Whenever it is possible that the safety protection features built into this equipment have been im-
paired, ISOLATE FROM THE POWER SUPPLY and do not use the equipment until safe opera-
tion can be verified by service-trained personnel. If necessary, return the equipment to Alcatel
After Sales for service and repair.
–DO NOT open equipment.
–Return the product to Alcatel Customer Service for servicing and repair.
–Recommendation to installers and maintenance operators: before carrying out any opera-
tions, check the equipotential bonding of the earthing devices to which our measurement equip-
ment and instruments are connected. If necessary, during installation, ensure the equipotential
bonding by electrical connection of these devices.
1.3.2 –Symbols on products
1.3.2.1 –Danger symbols
When subsystems and modules have warning labels, it is extremely important to follow their instructions.
These labels are designed to indicate dangerous situations; they may contain any standard symbol or
any text considered necessary to protect users and employees.
The most frequent danger situations and symbols are:
Danger or general warning

Close to dangerous voltages (>42.4 V AC peak, 60 V DC; power level 4240 VA) you
will find this warning label. Maintenance personnel is exposed to dangerous electri-
cal voltages when removing the cover.
Terminal for connecting the protective earth conductor in power supply wiring
Other earth terminal
Indicates compliance with essential requirements of the applicable European direc-
tives.
–protection of personnel,
–warning of a possible dangerous situation,
–danger of fatal or serious injury.
–protection of equipment,
–warning of a procedure, practice or condition that could be dangerous to equi-
pment or its environment,

2 Equipment overview
2.1 Overview of the A7390 system
The Alcatel 7390 is a multi-service broadband wireless local loop system designed to provide telecom
services to small and medium-sized enterprises.
Broad band WLL (Wireless Local Loop) system, Alcatel 7390 allows operators to offer rapid provision -
to a large number of client sites - of a comprehensive range of telephone and data transmission
services.
For cellular phone network operators, Alcatel 7390 offers the possibility of linking base stations to
base station controllers. This makes Alcatel 7390 an economical transmission solution, for the
implementation or extension of high traffic density areas coverage.
For mixed network operators (fixed and mobile), Alcatel 7390 enables to connect, with the same
system, fixed professional end user as well as base stations of cellular telephony.

2.3.3 Capacity
The system capacity depends on the traffic mix between data services (transported on ATM cells) and
leased lines or telephony services (transported on TDM circuits)
It also depends on the channeling and the number of upstream channels.

2.4 Description of the Terminal Station (7390TS)
The A7390 system Terminal Station (7390TS) consists of the following main elements:
–an external transceiver constituting the radio antenna part and designated "RT" (Radio Termina-
tion);
–a user connection unit constituting the "indoor" part and designated NT (Network Termination);
–a cable linking the RT and NT (NT/RT link);
–depending on the configurations (see sections 2.5, 3.8, 3.9), one (or more) repeater module(s),
or (and) one (or more) splitter module(s).

Figure 3 – Example of assembly with passive splitters and repeaters
The system can support 2 repeaters and 2 passive splitters per route. The route is the path between a
NT unit and a RT unit.
The fixed distance between 2 repeaters or between a repeater and a NT unit is 50 meters if one passive
splitter is used.
The fixed distance between two repeaters or between a repeater and a NT unit is 24 meters if two
passive splitters are used.

3 Installation of the 7390TS Terminal Station
3.1 Equipment delivery
When you receive the equipment in its packaging:
–Check the condition of the packaging.
–If damaged, make your reservations known to the carrier 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.
Stages for integrated
1. Open the cover flap of the package lid (Figure 4 – Unpacking the RT unit with integrated antenna).
2. Remove the cardboard packing wedge protecting the box’s contents.
3. Remove the RT unit, taking care not to damage the antenna.
4. Remove the slotted casing from the box.
5. Remove the packaged items fixed in the slots of the casing.
6. Detach the drilling template if wall-mounting is to take place.
