within the FAU once power has been
applied.
DANGER:
HAZARDOUS VOLTAGES
Avoid electrical contact with the
telephone wires, hazardous voltages
may be present.
WARNING:
DANGER TO PERSONNEL
The FAU may fall down if it is
incorrectly mounted on pole.

General
The FAU is a device to enable the end user to make and receive telephone calls via
the Globalstar satellite network. This handbook describes how to plan the
installation, fit the FAU and prepare it for use. Please read the safety information
carefully. This issue covers the residential and PABX versions of the FAU only.

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.
