Product Description
Globalstar System
Globalstar is a low earth orbit (LEO) satellite-based telecommunications network
offering wireless telephone services worldwide. The Fixed Access Unit (FAU)
provides an interface for the end-user to access the Globalstar satellite network.
The FAU communicates using the Globalstar Air Interface (GAI) via the satellite
constellation to a number of groundstations or Gateways.
The gateway interconnects the Globalstar satellite network through a Cellular Switch
directly into the local Public Switched Telephone Network (PSTN). A diagram of the
Globalstar network is shown below.
The FAU is installed outdoors to provide an unobstructed view of the orbiting
satellite constellation, and cabling is run from the unit to a conventional telephone
socket mounted indoors, for easy connection of a telephone.
Typical Satellite Link
Fixed Access Unit (FAU)
The FAU comprises a single unit formed from a die-cast aluminium case enclosed
on four sides by moulded polycarbonate sunshields. Access to the single circuit
board contained within the aluminium case, is via the removable aluminium
backplate. The plate is secured using tamper-proof fixings.
Twin antennas - transmit and receive - attach to the top of the case using captive
screw fixings. The receive antenna incorporates a Low Noise Amplifier (LNA).
The mechanical design of the FAU is common to two applications and provides the
end user with an interface for connecting a standard telephone:
• Residential FAU - allowing connection of a telephone.
• PABX FAU - allowing connection of a range of PABXs.

Pre-Installation
The following activities will need to be carried out, before installation and
commissioning of the FAU at the subscriber’s site:
• Pre-installation Planning.
• Preparatory Field Engineering Work.
• Preparation and configuration of the FAU at the Engineering Depot.
Pre-Installation Planning
Pre-installation planning activities may include:
• Survey of subscriber location, address and mains voltage.
• Identify mounting location for FAU and type of pole/mast/wall fixing.
• Confirm position of the FAU is acceptable with customer/service provider.
• Identify position of possible interfering transmissions. This could be fixed
service microwave transmissions, radar pulses or a cellular base station.
• Identify position for FAU safety earthing system.
• Identify location for 48 V DC power supply.
• Identify position of any cross-connect unit/junction box and telephone socket.
• Determine and gain appropriate planning approval for the following cable
routes:
FAU - subscribers premises.
FAU - power supply.

Planning the Location for the FAU
When deciding on the location for the FAU attention should be paid to the following
planning recommendations:
• The FAU should be mounted to have a clear view of the sky, away from any
interfering sources or obstructions, see Figure below.
• The installation must be planned to place all equipment, cables, etc., out of reach
of the general public.
Clear View for Satellite Communication
• If the FAU is mounted on a building it must be at a minimum height of 2 metres
above the top of buildings with a clear view of the sky.
• Where two or three FAUs are to be mounted in the same area, they should be
separated by at least 1.2 metres. When there are more than three FAUs in the
same area, refer to Table 1 for recommended separation distances.

Radio Interference Sources (for Guidance Only)
In general the FAU will be unaffected by radio transmissions operating in the vicinity
of an installation. However, there are a small number of situations close to radio
transmitters where care should be taken in assessing the suitability of the site for
installing an FAU. If due care is not taken possible mis-operation of the FAU may
result or, in extreme cases, even damage.
NOTE: The information given is for guidance only. Worst case conditions have been
assumed throughout.
General Radar
An FAU may suffer damage if placed closer than:
•250 m of a general radar station operating near to the FAU receive band.
•150 m of a general radar station operating in the 5 GHz region.
Fixed Radio Services Operating in the FAU Receive Band
An FAU may be rendered inoperable if placed closer than:
•150 m from the centre boresight of a digital point-to-point microwave radio link.
•700 m of a digital point-to-multipoint base station using an omni-directional
antenna.
Cable Routing
The recommended cable types for use with the FAU allow the following maximum
separations:
Cable between FAU and DC Power Supply
For all applications, the cable between the FAU and its DC power supply should be
kept as short as possible, up to a maximum separation of 50 metres using standard
power cable. See Technical Data - Cables, for recommended cable types. Refer to
“Power Cable Lengths” on page 24 for relationship between cable gauge and
maximum length.

FAU Applications
Lightning Protection
Consideration should be given to protecting all external power and
telecommunication cabling against lightning especially where long lengths of
overhead cable will be run from the FAU to terminal apparatus.
Where lightning protection is considered necessary all protective devices should be
fitted in accordance with local regulations.
Switched DC Power Supply
The unit must incorporate a disconnection device to allow the unit to be isolated from
the primary power source.

It is recommended that the DC power supply unit incorporates its own ON/OFF
switch to allow the FAU to be powered ON and OFF remotely.
Pole Mounting
The FAU can be mounted on a standard pole, see Technical Data and Appendix.
The following maximum stub pole free lengths are supported subject to the local in-
country regulations.
• 1.5 metres maximum for nominal 50 mm diameter stub pole.
• 3 metres maximum for nominal 100 mm diameter stub pole.
NOTE: Since the FAU should be mounted at least 2m above the roof level or highest
obstruction (see “Planning the Location for the FAU” on page 4) the 50mm diameter
stub pole should only be used as a “jockey pole”, i.e. fitted to a mast. See “Typical
Wall and Pole Mounting of the FAU” on page 26 for an example.
Preparatory Field Engineering Work
The following checklist details some of the main engineering field activities, which
may need to have been completed before installing the FAU:
• Erection of mast / pole.
• Installation of the cross-connect box and line-jack socket(s) at the subscribers
premises/PABX installation.
• Cabling of AC mains supply to DC Power Supply Unit, if applicable.
• Installation of DC Power Supply Unit and any stand-by power supply.
• Installation of data and telephony cabling from FAU to payphone/residence.
• Installation of power supply cabling from FAU to DC power supply unit.
• Provision of earthing system for FAU.
Preparation and Configuration of the FAU
Preparation and configuration of the FAU at the installer’s depot is essential before
field installation can take place.
The following checklist details the pre-requisite activities to be carried out for each
FAU:
• Unpack the FAU and check all packaged contents, refer to check list enclosed in
packaging.
• Allocate SIM card to FAU.
• Place FAU on earthing mat, connect earth lead and attach earthing strap to wrist.

Assembling the FAU
Sun shields and antennas must be fitted to the FAU housing before fitting the unit to
a pole.
NOTE: Both front and rear sun shields must always be fitted.
1. Place the front sun shield in position on housing ensuring it locates correctly
with screw holes.
2. Position the rear sun shields and insert four screws through rear sun shield and
housing into front sun shield.
3. Tighten screws in turn to 0.8-1.0 Nm torque. Do not overtighten these screws or
the sun shields could be damaged.
Fitting Sun Shields
4. Insert sealing ‘O’ rings into antenna sockets of main housing.
5. Place both antennas in position; they are keyed to ensure correct location of each
antenna and mating of antenna connectors.
6. Secure the antennas using the captive screws and tighten to 0.8-1.0 Nm torque.

Fitting the Antenna
Fitting the FAU
The installer will first need to decide the appropriate method for installing the FAU,
see Pre-Installation.
1. Where conditions allow, mount the FAU on a pre-installed stub pole or mast, by
using the handle provided on the FAU. Typically, these situations will arise only
where the top of the pole can be reached safely and easily. Connection of cables
will then be possible after the FAU has been secured in position.
WARNING:
DANGER TO PERSONNEL
Do not install the FAU during a
lightning storm.
WARNING:
HAZARDOUS VOLTAGES
Use caution when installing or
modifying telephone lines as
hazardous voltages may be present.

FAU Installation Handbook
11
2. In situations where the top of the pole cannot be reached safely; FAU mounting
may be better achieved by mounting the FAU to the stub pole, connecting all
cables and then erecting and securing to the mast with the FAU in position.
The following procedure may need to be adapted to suit the chosen method of
installation:
1. Prepare the FAU for mounting at the top of the pole by loosely fitting the two
pole-clamps on the back of the FAU. The screw length will depend on the diam-
eter of the pole, e.g. a nominal 100 mm pole uses an 80 mm long screw, and a
nominal 50 mm pole uses a 25 mm long screw.
2. Lift the FAU over the top of the pole passing the pole through both brackets until
the top of the pole butts fully against the FAU handle/stop-plate, see below.
3. Secure the FAU to the pole by tightening the clamp bolts to 3±0.5 Nm torque.
